She was 41 years old. She was a licensed practical nurse at a Lawton, Oklahoma hospital who had worked the overnight shift for 8 years because the differential pay helped with her mortgage.
And because she was, by her own account, the kind of person who functioned better when the world was quiet.
On the morning of October 14th, 1986, she drove home from her shift as she did every morning, turned into her driveway on NW Maple Avenue, and did not come out of the house again.
That is not a story about a woman who was careless or unlucky or in the wrong place.
That is a story about a system that had the answer to what happened to Diane Louise Perez locked in an evidence room from 1987 onwards, and never once asked the question the evidence was waiting to answer.
And it would take 36 years, a new detective, and a phone call to a forensic lab to understand that the case had been solved from the inside for decades.
That the evidence room was, the whole time, holding the name of the man who killed Diane Perez in a sealed package that nobody had thought to open in the right way.
Before we get to what was in that package, we have to go back to Lawton.
We have to understand who Diane was. And we have to sit with the specific, clarifying fury of learning that the answer was in the building.
Lawton, Oklahoma in 1986 was a city of 80,000 in the southwest corner of the state.
A military and civilian city anchored by Fort Sill to the northeast and the Wichita Mountains to the west.
A place that had been shaped for generations by the rhythm of military cycles. Soldiers arriving, soldiers leaving, families putting down temporary roots that sometimes became permanent ones.
The civilian community that existed around and alongside the base was tight-knit in the particular way of cities that have learned to absorb change and maintain continuity simultaneously.
Diane Perez had been in Lawton since 1975 when she had moved from Tulsa with her then husband following a job transfer that had taken them south and west into a part of Oklahoma that neither of them had imagined living in.
She had stayed when the marriage ended in 1980 ended without particular drama without animosity without anything she would later describe as anything more than two people discovering that what had seemed like compatibility was actually proximity.
And that proximity, it turned out was not the same thing at all. She had kept the Lawton job.
She had kept the house she and her ex-husband had started to buy acquiring his half over 3 years through a financial arrangement that took considerable patience to execute but that gave her in the end a house that was entirely hers.
She had her nursing license by 1978 had taken the overnight shift at Comanche County Memorial Hospital because the differential pay helped with the mortgage and because she discovered in those first overnight weeks that she was constitutionally suited to the particular rhythm of a hospital at 3:00 in the morning.
The reduced staff the specific nature of the patients who were awake at that hour the way the building settled into a different mode of operation that required a different but no less demanding kind of attention.
She had been on the overnight shift for 8 years by 1986. She knew the building in the dark the way she knew her own kitchen.
She had a small house on NW Maple Avenue. She had a calico cat named Ruthie who had been her companion since 1981 and who had the temperament of a cat who had decided her household was satisfactory and had no intention of reconsidering.
She had a vegetable garden in the backyard that produced more tomatoes every summer than she could use which meant her neighbors received tomatoes regularly and without much ceremony left on doorsteps, handed over fences, pressed into service at every opportunity.
She had a sister in Tulsa named Connie who called every Thursday evening at 8:00 and with whom she had maintained for 4 years a running disagreement about a television drama they both watched and assessed differently.
Connie finding the lead character compelling. Diane finding the lead character exasperating. An argument that had no resolution and that both of them had come to understand was not about the television program at all but was simply the form their closeness had taken.
A standing joke that had outlasted any actual stakes. She was 41 years old and she was funny and precise and had seen enough in 8 years of overnight nursing to be entirely unshockable.
Which gave her a particular calm in situations that rattled other people. Her colleagues at the hospital described her as the nurse you wanted on a difficult night.
Not because she was aggressive or heroic but because she remained level while everything else tilted.
And that quality communicated itself through a ward and settled it. She was, her charge nurse said in an interview the week after she died.
The nurse that other nurses called when they were not sure what to do next.
She usually knew. When she didn’t, she said so. And that honesty was itself steadying.
On the morning of October 14th, 1986, Diane completed her overnight shift at 7:15 and drove home.
A neighbor saw her car turn into the driveway at approximately 7:40. The neighbor later said she had noticed because Diane was usually regular as a clock.
And she had glanced up from her own driveway to confirm it was Diane’s car.
And it was. By 4:00 in the afternoon, Connie had called three times and received no answer.
The answering machine had picked up each time. And Diane had not called back. Which was unusual enough that Connie had called the neighbor and asked her to go check.
The neighbor knocked on the front door. When there was no answer, she walked around to look in the kitchen window.
She called the police. Diane Perez was found inside her home. She had been strangled.
She had been there since the morning. There was no sign of forced entry. The front door lock had been engaged.
But the back door, which opened onto a small yard that was accessible from an alley behind the property, was unlocked.
The investigation was led by Detective Sergeant Pete Oberly of the Lawton Police Department. He was 48, a veteran detective who had worked the city for 22 years.
And he approached the Perez case with the methodical intensity that a homicide without obvious motive and without forced entry demands.
The absence of forced entry meant either Diane had let someone in, which she was careful enough not to do with strangers, or someone had a key or access through the unlocked back door, which anyone familiar with the property might have known about.
Oberli developed a list of persons of interest and worked through it systematically. He identified a man named Vernon Harold Meeks, 53 years old in 1986, a recently terminated employee of an HVAC company that had serviced Diane’s house twice in the previous year.
He had been on the property. He would have known the back door. He had, according to a former co-worker, made comments about Diane during a service call that the co-worker had found inappropriate and had noted to a supervisor, who had documented it.
Oberli interviewed Meeks in November 1986. Meeks was cooperative and unconcerned in a way that Oberli found professionally irritating without being able to act on.
He provided an alibi for the morning of October 14th. His wife confirmed he had been home.
The alibi was a spouse’s confirmation with no external corroboration. Here is what happened next, and this is the part of this case that takes the longest to process.
In January 1987, a routine collection of Meeks’s biological material was made in connection with a separate minor investigation that was subsequently dropped.
The material, a biological sample collected and tested for a matter that was resolved without charge, was logged and placed in the Lawton Police Department evidence storage.
It was logged correctly. It was preserved correctly. It was associated by case number with the minor investigation rather than with the Perez homicide.
Because at the time of its collection, it had not been associated with Diane’s case at all.
The biological material from Diane’s home and the biological material from Meeks’s 1987 collection sat in the same evidence facility in separate envelopes for 35 years.
The Perez case material was submitted to CODIS in 1996 when the national database was established and again in 2003 when the database expanded.
No match because Meeks’s 1987 sample had never been submitted to CODIS. It was in the building.
It was in the same building. Nobody had drawn the line between the two envelopes.
Oberle retired in 1998. He handed off the case with a note that said Meeks, Vernon was never eliminated.
The spousal alibi is weak. Oberle died in 2011 without seeing the case resolved. By 1998, the case had been reviewed three times without resolution and been listed as inactive.
Oberle retired that year handing the file to a detective named Pete Stansel who reviewed it comprehensively and identified the same problem Oberle had faced.
The physical evidence was insufficient. The alibi was weak but had two confirmations and nothing new had arrived to reopen the question.
Stansel resubmitted the CODIS profile in 2003 after the national database expanded. No match. Meeks’s wife died in 2005.
He had retired from HVAC work in 2003 after a knee injury made the physical demands of the job difficult to sustain.
He had a pension from a union he had been part of for 20 years.
He attended a local church. He had a brother in Texas who came to visit occasionally.
He was, to the neighbors on his Lawton Street, a widower of advancing age who kept his property tidy and whose lights went out early.
Nothing about him, from the outside, announced itself. Nothing from the outside ever does in these cases.
That is what makes them difficult. And that is why the inside, the evidence room, the archived sample, the cross-reference not yet made, matters so much.
Connie Shepherd, who had been Diane’s Connie her whole life, and who had resumed her maiden name after her own divorce in 1994, called the Lawton Police Department Cold Case Unit every year in October, the month of the anniversary.
She had been doing this since 1990. She always asked the same questions. Had the evidence been fully analyzed?
Had every person of interest been fully eliminated? Was there anything new? She was always told yes.
Sometimes the yes was more detailed than others. Sometimes the detective she reached had clearly read the file recently and could speak to it with specificity.
Sometimes the detective she reached was clearly covering a colleague’s phone and was working from general reassurance.
She was told yes for 32 years. The answer, the real, complete, full answer, was sitting in an evidence room in the same building from which she was receiving the reassurances, in a sealed envelope correctly logged and correctly preserved and attached to a case number that had never been cross-referenced to Diane’s homicide investigation.
It was there. It had had there since 1987. Connie called every October and was told yes.
And the evidence sat 12 feet from the detective’s desk. And nobody connected the two.
Every case on this channel is built on the belief that the evidence room should not be the last place anyone looks.

Now, let’s get back to Diane. Detective Corporal Marcus Webb joined the Lawton Police Department Cold Case Unit in 2021 with a specific mandate.
To conduct a comprehensive audit of all physical evidence in connection with unsolved homicides from 1980 to 2000.
Cross-referencing every archived sample against every CODIS submission from the same cases to determine whether any evidence had been collected but never submitted.
It was a bureaucratic task. It was the right bureaucratic task. In March 2022, Webb identified the discrepancy.
The Meeks 1987 biological sample, correctly logged, correctly preserved, never submitted to CODIS, never connected to the Perez homicide investigation, was sitting in the evidence facility.
Webb submitted it for CODIS comparison in April 2022. The result came back in 6 weeks.
The 1987 Meeks sample matched the 1986 biological evidence from Diane Perez’s home. Vernon Harold Meeks was 89 years old.
He was in a nursing care facility in Lawton. He was in frail health. Webb obtained a confirmatory DNA sample through a swab collected at the care facility with the assistance of medical staff.
The match was confirmed in August 2022 by the Oklahoma State Bureau of Investigation. On September 19th, 2022, Meeks was charged with the first-degree murder of Diane Louise Perez.
He was 89 years old and in a nursing facility. His attorney entered a not guilty plea on his behalf.
He died in the care facility on December 3rd, 2022, before the case went to trial, never having spoken publicly about what he had done.
The case has been closed as a solved homicide with a deceased perpetrator. Connie, who was 83 years old when Webb called her in September 2022, sat in her Tulsa home and listened to the explanation of what had happened, that the sample had existed since 1987, that it had been in the evidence room, that the cross-reference had never been made until now, that 35 years of her annual October calls had been answered with yes when the full answer was, “We have it, but we haven’t connected it yet.”
She was quiet for a long time. Then she said, “Diane deserved better than 36 years.”
She said it without anger. She said it the way people say things that are simply finally true.
The Lawton Police Department issued a formal statement acknowledging the evidence management failure that had allowed the 1987 sample to remain unconnected to the Perez case for 35 years.
A new evidence cross-referencing protocol, requiring that all biological samples collected from persons of interest in active homicide investigations be submitted to CODIS regardless of the investigative context of collection, was implemented in January 2023.
It is called the Perez protocol within the department. Diane Perez had a calico cat named Ruthie and a Thursday evening phone call with her sister about a television program they never agreed on.
And they had been not agreeing about it for 4 years with no signs of either of them changing their position.
Which was exactly the point. She had a house she had been paying down for 6 years and a vegetable garden that produced more tomatoes than she could use.
And a night shift calm that settled a ward and a whole life that was entirely, specifically, irreducibly hers.
The overnights. The neighbor’s glance confirming the regular return. The coffee maker timer set for a morning that was supposed to follow.
She drove home from her shift on a Tuesday morning and turned into her driveway on NW Maple Avenue and the neighbor looked up and confirmed it was her car and it was.
And then everything stopped. The answer to what stopped it was in the same building where the detectives were receiving Connie’s annual calls and telling her yes.
Two envelopes. One cross-reference that was not made. One protocol that did not yet exist.
Now the protocol exists. It is named for Diane. That is the least and also the most that the department could do.
And they have done it. And it is on record. And other women in other evidence rooms in other cities may eventually be the reason the protocol matters beyond its name.
Meeks has not spoken. He has not confessed. He died in a care facility having never offered an explanation.
Whatever he knew about what he did on the morning of October 14th, 1986, he kept.
But what he could not keep, what no one can keep in the end, once the right technology arrives, was the biological evidence he left behind in Diane’s house.
That outlasted him. It outlasted 36 years and three storage moves and a digitization program and a series of detectives who told Connie yes and meant it as best they could.
It waited. It was there. It was always there. The answer to what stopped it was in the building.
It was in a sealed envelope in a correctly logged, correctly preserved, correctly stored evidence system.
And it took 35 years and a detective with a cross-referencing mandate to draw the line between two envelopes that should have been connected in 1987.
It was not connected. Now it is. The name is on the file. The case is closed.
What does it mean to have the answer in the same room as the question for 35 years?
What does proper evidence storage mean when the storage is correct but the connection is never made?
And what do we do with the knowledge that 36 years of October phone calls from a woman in Tulsa were answered with a yes that was not quite the whole truth?
Leave those questions in the comments. They belong to Diane and to Connie and to the Perez protocol, which is the least the department could do and also exactly the right thing to do now.
36 years, two envelopes, one line that should have been drawn in 1987. Subscribe if you believe that cross-referencing matters.
The next case is in the description. Thank you for watching.
