On the morning of August 4th, 1981, William Quail walked 150 ft from his front door to his daughter’s house in Cherry Hills Village, Colorado.
Sylvia hadn’t shown up for their morning coffee. She always showed up. What he found inside would haunt a tiny police department for the next 41 years.
His daughter was dead. The phone lines had been cut. The killer had pried open a bathroom window, attacked her, and vanished into one of the safest suburbs in Denver.
There were no witnesses, no suspect, and no arrest. For four decades, Sylvia Quail’s murder sat unsolved.
The only homicide Cherry Hills Village had ever recorded. A serial killer even confessed to it.
He was lying. Then in 2021, a vanilla Coke can in a Nebraska dumpster [music] changed everything.
This is the story of Sylvia Quail, the woman everyone loved, the case everyone thought would stay buried, and the 41-year road to redemption.

To understand what Cherry Hills Village lost on that August morning, you have to understand who Sylvia Quail actually was.
Because the headlines would reduce her to a victim, a case [music] number, a name on a file.
She was so much more than that. Sylvia May Quail was 34 years old in the summer of 1981.
She’d grown up in the area, graduated from Englewood High School, and worked as a secretary at an architectural firm.
On paper, that sounds like a quiet life. In practice, Sylvia [music] was anything but quiet.
She was a history buff who spent hours researching the work of her uncle, Wesley Quail, an architect whose buildings she found endlessly fascinating.
She would dig through old records, trace the story behind each structure, follow the thread of her family’s creative legacy through blueprints and building permits.
It wasn’t a casual interest. It was the [music] kind of deep sustained curiosity that tells you something about a person’s character.
She was an avid potter and not the kind who takes one class and puts a lopsided mug on a shelf.
Sylvia got genuinely good at it. Her ceramic pieces were beautiful enough that her sister Joe kept them displayed throughout her home for decades after Sylvia’s death.
Every time Joe walked through her own living room, her sister’s work was there, a reminder of what Sylvia could create when she sat down at a wheel and [music] lost herself in the process.
She was a talented cook who turned that talent into a [music] business, launching a small wedding cake company she called the Buttery.
If you got married in the Cherry Hills Village area in the late 70s or early 80s, there’s a chance Sylvia Quail made your cake.
She poured the same attention into her baking that she poured into her pottery and her research.
Everything Sylvia touched, she did with intention. But the thing people remembered most about Sylvia wasn’t what she did.
It was how she made people feel. Cherry Hills Village Police Chief Michelle Tovea speaking at a press conference 40 years after the murder described Sylvia as ambitious, vibrant, friendly, and the kind of person who lit up the room when she walked in.
Tovea said Sylvia had a lot of friends and would have given her last dollar to any one of them if they needed it.
Sylvia was fiercely close with her family. Her parents, William and Mary Quail, lived just 150 ft away from her house.
[music] Every single morning, Sylvia walked over for coffee. Not once in a while, not on weekends, every morning.
It was their ritual, the kind of thing families build their entire rhythm around without realizing how much it means until it’s gone.
She was also close with her younger sister, Joe. They talked on the phone regularly, checked in on each other, and shared the kind of bond that doesn’t weaken with age.
After Sylvia died, her family chose an inscription for her grave marker that said everything about how they saw her.
Beauty [music] scene is never lost. Sylvia Quail had her entire life ahead of her, a business she was building, art she was making, a family she saw every single morning.
And on the night of August 3rd, 1981, [music] all of it was taken from her.
Sylvia’s story is the reason this channel exists. Not just the crime, but the person behind it.
Someone who deserved to be remembered for the life she lived, not the way it ended.

To understand how a murder like this could go unsolved for 41 years, you have to understand where it happened.
Cherry Hills Village sits about 7 mi south of downtown Denver in Arapjo County. It was incorporated back in 1945, and by the early 1980s, it had become one of the most exclusive residential enclaves in all of Colorado.
The lots were enormous, often an acre or more. The streets were lined with mature trees.
The homes were set far back from the road behind long driveways and manicured hedges.
Country clubs dotted the landscape. NFL Hall of Fame quarterback John Elway would eventually call it home.
The population in 1981 hovered around 6,000 people. That’s a small town by any standard, but an especially small town when you consider the wealth concentrated in it.
This was the kind of place where neighbors waved at each other from across oversized lawns, where the biggest concern on any given Tuesday was whether someone’s sprinkler was running too long.
The Cherry Hills Village Police Department reflected that reality. It was a small force built for a community where serious crime simply didn’t happen.
Traffic stops, noise complaints, the occasional property dispute. That was the daily workload. The officers knew the residents by name.
They knew which families had lived there for decades and which were new arrivals. They patrolled wide streets where the most common call was a coyote sighting or a garage door left open overnight.
Murder investigations were not something this department had any experience with. They had no homicide unit because they had never needed one.
No cold case squad, no forensic specialists on payroll. When something went wrong in Cherry Hills Village, it was usually the kind of thing that could be resolved with a phone call or a knock on a neighbor’s door.
And here’s the detail that makes Sylvia’s case even more striking. Before August 4th, 1981, there had never been a recorded homicide in Cherry Hills Village.
Not one. In the entire history of the town, going back to its incorporation in 1945, no one had ever been murdered there.
Sylvia Quail’s killing wasn’t just a crime. It was the first of its kind in a place that had defined itself by its [snorts] safety.
The idea that someone could cut a phone line, pry open a window, and commit an act of horrific violence in a neighborhood where people didn’t even lock their doors at night that shattered something in Cherry Hills Village that would take decades to repair.
And it fell to a police department that had never handled anything like it. The last time anyone heard Sylvia Quail’s voice was around 11:00 on the night of August 3rd, 1981.
She was on the phone with her sister Joe. They talked the way they always did.
Nothing unusual, nothing alarming. Joe would later remember it as a perfectly normal conversation. They said good night and hung up.
Sometime between that phone call and the early hours of the following morning, someone came to Sylvia’s house on South Ogden Street with the intention of getting inside.
The approach was methodical. The killer started with the phone line. An exterior wire ran along the outside of the house, and the intruder grabbed a garden hose from the yard, threw it over the line, and used it to pull the wire down.
The disconnected line was later found draped across the hood of Sylvia’s brown 1974 Corvette parked outside.
Investigators noticed black marks on the garden hose where it had scraped against the phone wire.
Inside the house, the living room phone cord was also cut. Sylvia had no way to call for help.
Then the killer tried to find a way in. A small hole was cut into the screen of one of the bedroom windows, but the attempt to enter through that window failed.
So the intruder moved to the bathroom. There, the window screen was pried off entirely, removed from the frame, and carried more than 50 ft into the tall weeds behind the house.
Pry marks were visible on the bottom of the wooden window frame where a tool had been used to force it open.
Once inside, the killer attacked Sylvia in her living room. The violence was extreme and deliberate.
She was shot once in the top of her head with a 22 caliber bullet.
She was stabbed three times in the upper back, the wounds penetrating her heart and both lungs.
She was strangled with red marks consistent with finger pressure found on her neck and [music] throat.
She was sexually assaulted. Sylvia fought back. Her hands were covered in blood and several of her fingernails were broken and damaged.
She did not go quietly. A bloody kitchen knife was found near her body. The coroner determined that the primary cause of death was blood loss from the stab wounds.
The gunshot wound was listed as a secondary cause. When William Quail walked over to his daughter’s house the next morning and she didn’t answer the door, he let himself in.
What he found was beyond anything a father should ever have to see. His daughter was on the living room floor.
A bloody white towel had been placed over her face. William called 911 just before 8:00 in the morning.
The dispatch logged his call as a report of a woman down. Cherry Hills Village police arrived at the house on South Ogden Street within [music] minutes.
And the case that would consume their department for the next four decades had officially begun.
The Cherry Hills Village Police Department had never processed a murder scene [music] before. This was a department built for a town of 6,000 people where the worst thing that usually happened was a broken fence or a car [music] driving too fast through a residential street.
Now, they were standing in a living room where a young woman had been beaten, stabbed, shot, and killed.
But they rose [music] to the moment. Detectives and evidence technicians worked to the scene meticulously, ultimately collecting approximately 140 [music] individual pieces of evidence from Sylvia’s home.
Every surface was documented. Every item that could be relevant was bagged, tagged, and preserved.
The garden hose with the black marks, the pride window frame, the severed phone lines, the kitchen knife, the white towel.
Fibers from the orange area rug where Sylvia had been found. The problem was that none of it pointed to a specific person.
There were no usable fingerprints that led anywhere. No footprints outside the bathroom window, no murder weapon beyond the kitchen knife, which appeared to have come from Sylvia’s own kitchen.
Whoever did this had come prepared and left almost no trace of their identity behind.
Investigators canvased the neighborhood, knocked on doors, and interviewed everyone in Sylvia’s life. Friends, co-workers at the architectural firm, clients from the buttery, acquaintances, anyone who might have had a reason to know her schedule or know when she’d be home alone.
They went door to door through those wide, quiet streets, asking the same questions over and over.
Did you see anything unusual last night? Did you hear anything? Did you notice a car that didn’t belong?
Did anyone mention Sylvia recently? Nobody had seen anything. Nobody had heard anything. And that was the cruel irony of the neighborhood itself.
The very features that made Cherry Hills Village feel safe. The large lots, the generous setbacks from the road, the thick hedges and mature trees.
Those same features meant that a crime happening inside a house in the middle of the night could go completely unnoticed.
You could scream in your living room and your nearest neighbor 100 yards away behind a row of elms would never hear it.
The investigation consumed the department. Officers who had never worked a homicide were suddenly learning evidence preservation protocols and forensic terminology on the fly.
They consulted with larger agencies in the Denver metro area. They followed every lead, no matter how thin, and watched each one dissolve, into nothing.
2 years later, in 1983, forensic technicians returned to the preserved evidence with an alternate light source, a tool that can reveal biological material invisible to the naked eye.
On the orange area rug from Sylvia’s living room, they found what they described as potential foreign material.
It was a discovery that would become the most important piece of evidence in the entire case.
But in 1983, the technology to fully analyze it didn’t exist yet. DNA profiling was still in its infancy.
The material was documented, carefully preserved, and stored alongside the other 139 pieces of evidence from the scene, waiting for science to catch up.
One thing was clear from the beginning, though. This was not a crime of opportunity.
The phone lines were cut before entry. That alone was significant. Someone had taken the time in the dark to locate the exterior phone wire, find a garden hose, throw it over the line, [music] and pull it down.
That’s not something a person does on impulse. That’s [music] planning. That’s someone who has looked at this house before and identified how to isolate the person inside.
Multiple windows were tested before one was forced open. The bedroom screen was tried first.
A hole cut into it, but the window itself didn’t give. So, the intruder moved to the bathroom and removed the screen entirely, prying the frame with a tool.
The screen was then carried more than 50 ft away and hidden in tall weeds.
That’s not the behavior of a panicked burglar. That’s someone covering their tracks in real time.
Whoever killed Sylvia Quail had planned [music] this. They had come to her house knowing she was alone and they had taken deliberate, methodical steps [music] to make sure she couldn’t call for help and that their point of entry would be [music] harder to spot.
That level of premeditation meant the killer either knew Sylvia, knew her routine, or had surveiled her home beforehand.
But without a suspect to match that theory to, it remained exactly that, a theory.
And then [music] in 1983, the investigation took a sharp turn that would cost it an entire decade.
[music] His name was Odis Elwood Tulle. If you follow true crime, you’ve probably heard of him.
Tulle was a drifter, an arsonist, and a serial killer who roamed the country with his companion Henry Lee Lucas throughout the late 70s and early 80s.
Together, the two men confessed to hundreds of murders across dozens of states. Law enforcement agencies from coast to coast [music] were lining up to close their open cases using Tulle and Lucas as convenient answers.
In 1983, Tulle told investigators from the Colorado Bureau of Investigation that he had murdered Sylvia Quail.
He provided details about the area around her home, describing trees and hedges near the property with enough specificity that investigators took the confession seriously.
The Arapjo County District Attorney’s Office formally charged Audis Tulle with firstdegree murder in the death of Sylvia Quail.
For the Quail family, it must have felt like the beginning of an answer. Two years of silence, of not knowing, of walking past their daughter’s empty house every single day.
And now, a man had confessed. He’d been charged. Justice, [music] however imperfect, seemed to be arriving.
But there was a problem. Tulle was already in custody in Florida for other crimes, and the logistics [music] of bringing him to Colorado for trial proved complicated.
The charge sat open year after year. The firstdegree murder charge against Otis Tulle remained on the books in Arapjo County, but no trial was ever scheduled.
And here’s what that open charge did to the investigation. It froze it. With a suspect already identified and formally charged, there was no institutional urgency to keep looking.
The evidence sat in storage. The interviews slowed and then stopped. New cases came in.
Officers were reassigned. The quail file migrated from the active pile to a shelf because as far as the system was concerned, the case was functionally solved.
They had their man. They just hadn’t tried him yet. Meanwhile, the real killer was out there living freely.
And for all anyone knew, he could have been just a few miles away the entire time.
A decade passed. Then in 1993, DNA technology had advanced far enough to test the biological material found on the orange area rug [music] against Otis Tool’s genetic profile.
The results were definitive. Tulle’s DNA did not match the evidence from the crime scene.
He had not been in Sylvia Quail’s home. His confession was a lie. Arapo County District Attorney Bob Gallagher dropped the charges.
10 years. A full decade of the investigation’s life had been consumed by a false confession from a serial killer who made a hobby of claiming crimes he didn’t commit.
Tulle and Lucas had done this across the country, offering confessions that allowed police departments to close cases without doing the actual work of solving them.
And Sylvia Quail’s case had fallen into the same trap. Tulle died in a Florida prison in 1996.
He was never [music] tried for Sylvia’s murder because he had nothing to do with it.
The real killer was still out there. And the Quail family was right back where they started.
If this story is hitting you the way it hit me when I first researched it, take a second to drop a like on this video.
It helps more people find these cases and that matters especially for the ones that almost stayed buried.
After the tool charges were dropped in 1993, the quail case entered the quietest and most painful phase of its life.
There were no new leads, no new suspects, and no new technology capable of telling investigators who had left that biological material on the orange area rug.
In 1995, the Cherry Hills Village Police Department took a step that wouldn’t pay off for years, but would eventually become the foundation of everything.
They cut out the seaman stained section of the orange rug and submitted it to the Colorado Bureau of Investigations Crime Lab for DNA analysis.
The technology had improved since the early8s and CBI was now capable of extracting a usable genetic profile from degraded biological evidence.
5 years later in 2000, the lab succeeded. They developed a complete male DNA profile from the rug sample.
That profile was uploaded to KOTUS, the FBI’s [music] combined DNA index system, a national database containing millions of DNA profiles from convicted offenders, [music] arrestes, and forensic evidence from unsolved cases across the country.
No match. The DNA profile sat in cotus like a letter with no return address.
It belonged [music] to someone. It proved that an unknown male had been present at the scene of Sylvia Quail’s murder, but without a matching profile in the system, it couldn’t tell investigators who person.
The killer’s genetic code was sitting in a federal database waiting. And every time a new [music] offender’s DNA was entered into the system, every time a new arrest kit was processed in a crime [music] lab somewhere in the country, the system would automatically run a comparison against all the unmatched profiles, including the one from the orange area rug in Cherry Hills Village.
Year after year, the answer came back the same. No match found. And while the DNA waited in its digital holding pattern, time took its toll on the people who needed answers most.
William Quail, the father who had walked 150 ft to find his daughter’s body on that August morning, died in 1999.
He was buried without ever knowing who killed Sylvia. 18 years he had lived with that morning.
18 years of walking past her house. 18 years of mornings without the coffee ritual that had anchored every single day of their family’s life.
When he died, the case was still cold and the DNA profile in Cotus was still waiting for a match that hadn’t come.
About 10 years later, around 2009, Mary Quail also passed away. Sylvia’s mother, the woman who had raised her, who had lived just 150 ft away, who had surely heard sirens pulling up to her daughter’s address on that August morning in 1981.
[music] She had spent nearly three decades watching investigators come and go, watching new detectives take over the case and introduce themselves, [music] watching technologies change and promises get made.
And she died without ever learning who had done this to [music] her daughter. The two people who had suffered the most from Sylvia’s murder, [music] the parents who discovered her body and spent every remaining year of their lives waiting for a name, never saw [music] justice.
William died before the DNA was even extracted from the [music] rug. Mary died before genetic genealogy was a tool any police department had ever used.
That fact sits at the [music] heart of this story, and it’s the kind of cruelty that no sentencing hearing, no matter how cathartic, can ever undo.
But the case was not abandoned. Sylvia’s sister, Joe Hammet, and her husband, remained in Cherry Hills Village.
They stayed in contact with the police department. They called, they asked, they reminded the investigators that someone was still waiting.
And the Cherry Hills Village Police Department, small as it was, never fully let go of the case.
This was the one thing the department got right through every setback, [music] every false lead, every decade of silence.
Officers retired and new ones took their places, and each incoming detective was told about the Quail case.
Each one reviewed the file. Each one understood that this was unfinished business. The department couldn’t solve it, not with the tools they had, but they could keep it alive, and they did.
In 2013, the 18th Judicial District, which handles prosecution for Arapjo County, launched a dedicated cold case unit.
The Quail case was one of the files they picked up. [music] Fresh eyes, fresh resources, a renewed commitment to the cases that other people had given up on.
Chief Michelle Tovea would later say that the folks who came before her, other detectives across the years, always kept this case on the front burner and never gave up on it.
For a department of its size, that persistence was remarkable. Most small town police agencies would have let a case like this fade into the archives.
Cherry Hills Village didn’t. For 20 years, the DNA profile in Cotus waited for its match.
And for 20 years, it didn’t find one. But the people who were supposed to care about it never stopped caring.
And that made all the difference when the right technology finally arrived. In 2019, something shifted.
Metro Denver Crimestoppers, the nonprofit organization that funds and promotes tips on unsolved crimes, entered into a partnership with a Denver-based forensic genetic genealogy firm called United Data Connect.
UDC had been co-founded by Mitch Moresy, the former district attorney of Denver, and it specialized in a relatively new investigative technique that was transforming cold cases across the country.
The concept behind forensic genetic genealogy is both brilliant and painstaking. Traditional DNA matching, the kind used in COTUS, works by looking for an exact match.
If the suspect’s DNA is already in the system, you get a hit. If it’s not, you get nothing.
It’s like searching a phone book for a specific number. If the number isn’t listed, the phone book can’t help you.
Forensic genetic genealogy takes a completely different approach. Instead of looking for the exact person, it looks for their relatives.
Genealogologists upload the crime scene DNA to open-source consumer genealogy platforms, the same databases that millions of ordinary Americans use to trace their ancestry and find longlost cousins.
When the DNA finds partial matches, third cousins, fourth cousins, people who share a distant ancestor with the unknown suspect, the genealogologists begin building a family tree.
Branch by branch, connection by connection, they work backward and forward through generations, using public records, vital statistics, obituaries, and census data to fill in the gaps.
Eventually, the tree narrows to a single person who fits the profile. Someone who is the right age, lived in the right area, and sits at the exact intersection [music] of every genetic branch.
UDC had recently used this approach to solve a cold case in Jefferson County, Colorado.
After that success, a young DNA analyst at the firm suggested that Moresy reach out to Cherry Hills Village detective Lenny Abida, who was still working the quail case.
Moresy [music] made the call. In January of 2020, Cherry Hills Village cold case detectives and investigators from the 18th Judicial District formally brought Sylvia Quail’s case to the partnership.
The crime scene DNA, the same profile that had sat unmatched in Cotus for two decades, was sequenced and uploaded to two consumer genealogy databases, Family Tree DNA and GED Match.
Almost immediately, the system began returning partial matches, distant relatives of the unknown male whose DNA had been found at the scene of Sylvia’s murder.
Morrisy would later describe the process to CBS [music] Colorado. We started to then get connected people that were related to the individual that we were looking for.
The team used DNA, newspapers, [music] public records, vital statistics, and genealological databases to map out who these distant relatives were, how they were connected to each other, and where the branches of their family tree [music] intersected.
The tree grew to more than 3,300 people, 3,300 names, all connected to the unknown man who had been in Sylvia’s living room on the night she was killed.
By April of 2020, UDC’s [music] top genealogologist had followed the branches far enough. Every line of the family [music] tree converged on a single person of interest.
His name was David Dwayne Anderson. [music] Anderson was living in Koad, Nebraska, a small town of about 4,000 people in the central part of the state.
He was employed at a manufacturing company in nearby Goththingberg. He had a wife and children.
He had been living what appeared to be a completely ordinary life for decades. But when investigators pulled his criminal history, the picture changed.
In 1981, at the age of about 21 or 22, David Dwayne Anderson had been living in Englewood, Colorado.
That’s just a couple of miles south of Cherry Hills Village, just a couple of miles from Sylvia Quail’s house on South Ogden Street.
And his record from that era told a very specific [music] story. Colorado Bureau of Investigation records showed a long, detailed arrest history.
Between 1981 and 1986, Anderson had been arrested for at least eight home and business burglaries across the Denver metro area.
He operated across jurisdictions, hitting homes and businesses in Arvvada, Arapjo County, Adams County, Jefferson County, Englewood, [music] Federal Heights, and Logan County.
In at least two of those burglaries, he wore gloves to avoid leaving fingerprints. And in one home burglary, his method of entry was to remove a window screen and toss it into the yard before prying the window open.
The same method used to enter Sylvia Quail’s bathroom on the night she was killed.
The bathroom screen had been removed and carried more than 50 ft away. The window frame showed primarks from a tool.
It was the same signature. His first recorded contact with law enforcement in the Cherry Hills Village area was a traffic charge back in 1976, which meant he had been familiar with the community and its streets for at least 5 years before the murder.
In June of 1981, just 2 months before Sylvia’s murder, Anderson was arrested twice for burglary, once in Arvvada and once in Arapjo County.
The man was [music] actively breaking into homes in the Denver suburbs during the exact period when Sylvia was killed 2 months after the murder.
In October of 1981, [music] Jefferson County deputies arrested him for yet another burglary, and he received a 3-year state prison sentence.
After his release, the burglary arrests continued through 1986, and in 1988, he was charged with escape.
His last known Colorado arrest was in 1989, after which he eventually relocated to Nebraska.
The pattern was clear. Anderson was an active serial burglar who operated across the Denver metro area, who lived near the victim, who used the same entry techniques found at the crime scene, and whose criminal activity bracketed the exact time period of the murder.
But a pattern is not proof. To confirm that David Dwayne Anderson was the man whose DNA was found in Sylvia Quail’s home, investigators needed his DNA, and they needed to get it without tipping him off.
On January 18th, 2021, United Data Connect investigator Robert Fuller made the drive to Koad, Nebraska.
Koad is a small town of about 4,000 people in Dawson County, roughly 230 mi northeast of Denver along Interstate 80, the kind of place where a stranger sitting in a parked car gets noticed.
Fuller had to be careful. He positioned himself near Anderson’s apartment complex and waited. The goal was straightforward, but required patience and a bit of luck.
They needed Anderson’s DNA, and they needed to get it without his knowledge. If Anderson discarded anything that might carry his biological material, Fuller would collect it from the trash.
Under established legal precedent, once a person places garbage in a public dumpster, they’ve abandoned it.
Anyone can take it. Hours [music] passed and then Anderson cooperated without knowing it. He walked out of his apartment carrying two black trash bags, crossed the parking lot to the dumpster behind the complex, tossed them in, and went back inside.
Fuller waited until Anderson was out of sight, then moved to the dumpster and recovered both bags.
Back at his vehicle, he went through the contents with the precision of someone [music] who understood that everything depended on what he found.
He was looking for anything that Anderson’s lips, hands, or saliva might have touched. Bottles, cans, food containers, utensils, anything with a surface that might hold DNA.
He identified 15 items worth testing. Among them were a vanilla Coke can, a Great Value water bottle, a bottle of spiced rum, and a Michelob Ultra beer bottle.
Ordinary garbage. The kind of things millions of Americans throw away every day without a second thought.
But one of those items was about to close a 40-year-old murder case. Each item was individually bagged and sealed.
2 days later, on January 20th, Fuller drove to a travel stop in Sterling, Colorado, [music] where he met a Colorado investigator and handed off the evidence.
Cherry Hills Village evidence technicians took custody of the items and submitted them to the Colorado Bureau of Investigation for DNA analysis.
9 days. That’s how long it took. On January 29th, 2021, CBI delivered the results.
The male DNA profile developed from the vanilla Coke can was a match, not a partial match, not a probable match, a definitive match to multiple items of evidence from Sylvia Quail’s body and residence.
Anderson’s DNA matched evidence recovered from carpet fibers on the orange area rug where Sylvia’s body had been found.
The same rug where forensic technicians had found potential foreign material back in 1983 using an alternate light source.
The same rug that had been cut and submitted to Sebean in 1995. The same evidence that had produced the Kotus profile in 2000 that sat unmatched for two decades.
All of it pointed to the same man, a man who had been living quietly in Nebraska while the evidence waited for science to catch up.
Anderson’s DNA also matched evidence collected during Sylvia’s autopsy. It matched a swab taken from Sylvia’s body.
And the white towel that the killer had draped over Sylvia’s face, the same towel that William Quail had moved to cover his daughter when he found her that morning, contained a mixed profile of Sylvia’s blood.
And Anderson’s biological material. The forensic picture was complete. Anderson had been there. He had left his DNA on the victim, on the rug, on the towel.
There was no innocent explanation for that pattern. 40 years of waiting. A family tree of 3,300 names.
3,300 people who were not suspects, but whose genetic connections formed a map that led branch by branch to a single apartment complex in a small Nebraska town.
And it came down to a soda can in a dumpster. On February 10th, 2021, law enforcement officers arrested David Dwayne Anderson near Koad.
He was booked into the Dawson County, Nebraska Jail. He waved extradition to Colorado. Two weeks later, on February 25th, Cherry Hills Village Police Chief Michelle Tovea and Mitch Moresy stood before cameras at a press conference and announced the arrest.
Torea described Sylvia for the public, many of whom had never heard her name before.
She called Sylvia ambitious, [music] vibrant, friendly. She said Sylvia was the kind of person who lit up the room when she walked in and would have given her last dollar to anyone who needed it.
For the first time in 40 years, the public got to hear about who Sylvia Quail actually was, not as a victim, but as a person.
Moresy, who was himself the father of a young woman close to the age Sylvia had been when she died, became visibly emotional at the podium.
He described what William Quail must have experienced on the morning of August 4th, 1981.
Walking those 150 ft, opening his daughter’s door, finding her on the living room floor, Morrisy told the press that he couldn’t imagine as a father of a young woman about the same age having a morning like that, the way she had been left after being brutalized and killed.
His voice broke as he said it. Here was a former district attorney, a man who had spent decades in the criminal justice system who had seen the worst of what people do to each other.
And he couldn’t hold it together when he thought about what Sylvia’s father had walked into.
For Joe Hammet, Sylvia’s sister, the arrest was the moment she had spent four decades waiting for.
She and her husband were still living in Cherry Hills Village. They had never moved away from the community where Sylvia had been killed.
They had never stopped asking the police department if there was anything new. And now after all those years be after watching both of her parents die without an answer, Joe finally had a name.
David Dwayne Anderson was charged with two counts of firstdegree murder. The first count alleged that the killing was committed after deliberation.
The second alleged felony murder, meaning the killing occurred during the commission of another serious felony.
Because the crime took place in 1981, Anderson would be prosecuted under the sentencing laws that were in effect at that time, not under current Colorado statutes.
That legal distinction mattered enormously. Under 1981 law, a firstdegree murder conviction carried a sentence of life in prison with the possibility of parole after 20 calendar years.
Under current Colorado law, first-degree murder carries life without the possibility of parole. Anderson, by virtue of having committed the crime 41 years earlier, would face a significantly more lenient maximum sentence than a killer convicted today.
When investigators first questioned Anderson, he told them he didn’t know Sylvia Quail. He said he had no idea how his DNA ended up at the scene.
But by the time the case went to trial, his defense attorneys had shifted to a different strategy entirely.
In their opening statements, they told the jury that Anderson and Sylvia had engaged in consensual sex.
They didn’t explain how or when this alleged relationship had occurred. They didn’t present evidence of it, but they offered it as an alternative explanation for the DNA.
The defense also pointed to another man, Sylvia’s on andoff boyfriend, Pete Roma, whose DNA had reportedly been found on a knife at the scene.
The defense argued that police had ignored the most obvious suspect from the very beginning.
They painted a picture of a flawed investigation, one that had been so eager to accept Otis Tool’s false confession that it had failed to scrutinize the people closest to Sylvia.
One of Anderson’s defense attorneys told the jury that the original investigators had gotten caught hook, line, and sinker by Tool’s lies, and that their fixation on the serial killer had blinded them to a suspect who had been right in front of them the entire time.
It was a strategy designed to create reasonable doubt, not by disproving the DNA because the DNA was essentially irrefutable, but by offering an alternative story for how it got there.
If the jury believed that Anderson and Sylvia had been intimate at some point, then the DNA at the scene didn’t necessarily prove he was the killer.
And if the jury believed that another man with a violent history towards Sylvia had been overlooked, then maybe the real murderer was someone else entirely.
The first trial began on March 1st, 2022 before Arapjo County District Judge Darren Vale.
The prosecution laid out the DNA evidence, the burglary pattern, the window screen entry method, the criminal history, and the geographic proximity.
The defense countered with the consensual sex theory and the alternative suspect. The jury deliberated for 5 days.
5 days of the Quail family sitting outside a courtroom 41 years after the murder, waiting for 12 strangers to decide whether the man they’d been told was responsible would be held accountable.
The jurors could not reach a unanimous verdict. On March 8th, 2022, Judge Vale declared a mistrial for Joe Hammet.
It was another blow in a lifetime of blows. 41 years of waiting. And when the moment finally came, when 12 people sat in a room with all the evidence in front of them, they couldn’t agree.
The system that was supposed to deliver the answer her parents never lived to receive had stalled again.
Imagine sitting outside a courtroom for 5 days knowing that the man who killed your sister is sitting inside and waiting for a verdict that never comes.
That’s where Joe Hamit was in March of 2022. But the 18th Judicial District Attorney’s Office was not finished.
They announced almost immediately that they would retry the case. Prosecutors Grant Gkabauer and his team went back to work [music] reviewing the transcripts from the first trial, refining their presentation of the evidence, and preparing to put everything in front of a second jury.
Dropping the case was never a consideration. They had the DNA. They had the match.
They had the pattern. They just needed 12 people to agree on what it all meant.
In late June of 2022, David Dwayne Anderson went before a jury for the second time.
The prosecution built its case around the same pillars, but tighter, sharper, with the benefit of having seen what had given the first jury pause.
The DNA was irrefutable. Anderson’s genetic material had been found on the victim’s body, on the rug beneath her, and mixed with her blood on the towel covering her face.
His criminal history showed a pattern of residential burglaries using the exact same entry method found at the crime scene.
He had been living 2 miles away at the time of the murder. His arrest history bracketed the date of the killing with burglary charges 2 months before and 2 months after.
The prosecution connected every dot and left no room for an innocent explanation. On June 30th, 2022, the second jury returned its verdict.
Guilty on both counts of first-degree murder. Deputy District Attorney Grant Graco addressed the press afterward.
He said that for more than 40 years, the defendant had carried with him a dark secret, a secret that was finally revealed during this trial.
District Attorney John Kelner speaking publicly about the conviction said that when the 18th Judicial District first started its cold case unit in 2013, this was a case most people said would never be solved.
He added that time and science march on. And he finished with a message directed at anyone who believed they had escaped accountability for a violent crime.
For any killer who thinks they got away, Kelner said, “Know that we are still coming for you.
The sentencing was set for August 4th, 2022. That date was not chosen at random.
It was the 41st anniversary of Sylvia Quail’s murder. The same calendar date on which William Quail had walked 150 ft and found his daughter on the living room floor.
The same date on which Cherry Hills Village had recorded its first and only homicide.
41 years later, in the same county where the crime had occurred, the case would finally close.
In the Arapjo County courtroom, where two juries had heard the evidence, where the first had failed to agree and the second had convicted, Judge Darren Vale imposed the maximum sentence available under 1981 law, life in prison with the possibility of parole after 20 calendar years.
Anderson’s first parole hearing is scheduled for March of 2041. He will be in his 80s.
At sentencing, prosecutor Grant Grabauer spoke about the asymmetry of what had happened. He said Anderson went on to live his life as if everything was normal.
He got to experience marriage and kids. And then Gross Gabbau said what everyone in that courtroom was thinking.
Sadly, Sylvia never got to experience those things. [music] Anderson had gotten 41 years of freedom.
41 years of waking up, going to work, eating dinner, watching his children grow. Every one of those years was a year Sylvia [music] didn’t get.
Every one of those years was a year her parents spent in anguish. Then Joe Hammet stood up.
Sylvia’s younger sister, the woman who had been the last person to speak to Sylvia alive, the woman who had stayed in Cherry Hills Village for four decades and never stopped asking the police what they knew, stood before the man who had murdered her sister and read her victim impact statement.
She told the courtroom that Sylvia’s murder had turned her family’s world upside down. She said Anderson had lived for the last four decades without giving his crime or her sister a second thought while her family had suffered irreparable mental and emotional anguish during the time of uncertainty.
And then Joe said something that nobody in that courtroom expected. She said she had found it necessary to forgive David Dwayne Anderson, but she added, “He needs to bear the consequences of his actions.”
Outside the courthouse after the sentencing was complete, Joe spoke to reporters. Her words were simpler this time.
He needs to pay the consequences for what he’s done, she said. And he did today.
The weight of what was gained and what was lost on that day is impossible to fully measure.
Sylvia’s parents, William and Mary Quail, the two people who had carried the heaviest burden of not knowing, never saw the arrest, never saw the trial, never saw the sentencing.
William had died in 1999. Mary around 2009, both before the DNA genealogy technology that solved the case even existed.
Joe Hammet saw it. She carried the family’s grief into that courtroom and she carried it back out.
And the sentencing fell on the exact anniversary of the crime, 41 years to the day.
A symmetry so precise it felt less like coincidence and more like the universe finally catching up.
Anderson’s legal fight didn’t end with his conviction. His defense team appealed, challenging the legality of how investigators had obtained his DNA.
The core question was this. [music] Did the Fourth Amendment require police to obtain a warrant before pulling someone’s trash out of a dumpster and testing it for DNA?
Anderson’s attorneys argued that it did. They contended that a person who throws away a soda can does not does not intend to surrender their genetic information to the government.
DNA contains the most intimate biological data a person possesses. It reveals ancestry, health predispositions, family relationships.
Tossing a vanilla Coke can into a dumpster, the defense argued, is not the same as consenting to have your entire genetic code analyzed by law enforcement.
In August of 2026, a divided Colorado Court of Appeals ruled against Anderson in a 2:1 decision.
Judge Craig Welling wrote the majority opinion holding that neither the US Constitution nor the Colorado Constitution required investigators to obtain a warrant before collecting Anderson’s discarded trash.
Judge W Eric Cun concurred with the result but wrote a separate opinion expressing deep reservations.
[ __ ] said he was mindful of the tremendous potential for abuse inherent in such personal information residing in the hands of the government or indeed a private actor.
He urged legislators to continue focusing on privacy concerns as DNA technology continued to evolve.
Judge Timothy J. Shutz dissented outright. Shutz wrote that a person who discards a soda can does not intend to give the government the keys to their genetic code.
He argued the solution was simple. Police should just get a warrant. The split decision captured a tension that extends far beyond this single case.
Forensic genetic genealogy has solved hundreds of cold cases across the country. It has identified the Golden State Killer.
It has given names to unidentified victims who lay in unmarked graves for decades. It has brought closure to families who had given up hope.
But the same technology that finds killers also maps the genetic connections of millions of people who have committed no crime.
Every time a consumer uploads their DNA to an ancestry database, they make it possible for investigators to identify not just themselves, but their parents, their [music] siblings, their cousins, and their children.
For the Quail family, the question was never complicated. The technology gave them something that 41 years of traditional investigation could not.
It gave them the name of the man who killed Sylvia. It gave them a trial.
It gave them a verdict. Whether the rest of society can accept the tradeoff, privacy for justice, is a question that courts and legislators will be debating for years to come.
David Dwayne Anderson’s case will be one of the precedents they cite when they do.
On the morning of August 4th, 1981, a father walked 150 ft to check on his daughter because she hadn’t come for coffee.
William Quail did not live to see the man responsible for his daughter’s death identified.
He died in 1999. Neither did Mary Quail, who passed away around 2009. The parents who carried the deepest wound never received the answer they spent their remaining years waiting for, but Joe Hammet did.
Sylvia’s younger sister was there when the arrest was announced. She was there through the mistrial.
She was there when the second jury came back with a guilty verdict. She was there on August 4th, 2022 when the judge handed down the sentence on the exact anniversary of the murder.
[music] And she was there to stand in front of the man who killed her sister and tell him that she forgave him while also insisting he faced the consequences of what he had done.
Sylvia Quail was more than the worst thing that ever happened to her. She was a potter whose ceramic pieces her sister kept for decades.
She was a baker who started a wedding cake business because she loved making beautiful things for the most important day of people’s lives.
She was a history buff who spent hours tracing the work of her architect uncle.
She was the kind of person who, in the words of the police chief who would eventually help bring her case to its close, lit up the room when she walked in.
She was a daughter who never missed morning coffee. Not once until the morning she couldn’t.
The inscription on her grave reads, “Beauty seen is never lost.” Her family chose those words because they wanted [music] the world to remember Sylvia for who she was, not for what happened to her.
And after 41 years of a case that everyone thought would stay buried, after a serial killer’s false confession and a DNA profile that waited two decades for a match and a soda can in a Nebraska dumpster, that inscription turned out to be true.
The beauty of Sylvia’s life was not lost. It was carried forward by a sister who never stopped asking, by a police department that never stopped working, and by a technology that didn’t exist when the crime was committed, [music] but arrived just in time to answer the question that had haunted Cherry Hills Village for four decades.
David Dwayne Anderson is currently held at Sterling Correctional Facility in Colorado. His conviction was upheld by the Colorado Court of Appeals.
His first parole hearing is scheduled for March of 2041. Cherry Hills Village Police Chief Michelle Tovea, reflecting on the decades of work that brought the case to this point, said it best.
This was truly a team effort that spanned the course of almost 40 years. Folks that came before me or other detectives still kept this case on the front burner and never gave up on it.
They didn’t give up. Joe Hammet didn’t give up. And because none of them gave up, Sylvia Quail’s name is no longer attached to an unsolved case file.
It’s attached to a conviction. If Sylvia’s story stayed with you, share this video with someone who cares about these cases.
