May 18th, 1995, [music] a demolition crew was taking down a car dealership at 1515 Danforth Avenue in the east end of Toronto, just west of Coxwell.
The building had stood there [music] for decades.
Robertson Motors, cars in the showroom, cars on the lot, a service garage at the back with a concrete floor that had been walked [music] on and driven on and rolled across on mechanics creepers for as long as anybody in that neighborhood could remember.
The crew broke up the concrete floor.
Underneath the concrete was soil, which is what you expect.
And in the soil was a woman.
She had not fallen there.
Someone had dug a grave, laid her in it, and covered her over.
And at some point after that, a floor had been poured across the top of her, and a business had opened above [music] her head, and for the better part of half a century, people had come in off the Danforth to buy cars, while she lay 6 ft under the showroom.
She had been struck at least six times in the head with something the forensic examination could only describe as a hammer-like weapon.
Within days, her death was classified as a homicide.
And then the investigation stopped [music] almost exactly where it had started because the Toronto Police Service had a murdered woman and no idea in the world who she was.
They would not find out for another 31 years.
[music] By the time they did, she had been dead for 90 years.
The man police would eventually name had been dead for 41 of them.
And in all that time, in the entire country, there was no piece of paper anywhere with her name on it saying that [music] she was missing.
This is not a story about who did it.
Police worked that out in the end and the answer is close to the first thing you would guess.
This is a story about a woman who disappeared so completely that the disappearance itself left no mark and about what it took 90 years later to give her back her name.
And it starts on the other side of an ocean.
If you are new to this channel, we give cold cases the room they actually need, which is usually the room the people inside them never got.
Subscribe [music] because what is coming is the part of this that should have been written down and wasn’t.
Now, Aberdine, 1905.
[music] Mary Mloud Davidson was born in Aberdine in the northeast of Scotland in 1905.
In 1913, when she was 8 years old, her family immigrated to Canada.
That is very nearly the whole of what the public record holds about the first 30 years of her life.
[music] And that fact is the entire case in miniature.
We have the county she was born in.
We have the year her family got on a ship.
There is no school photograph in the file.
There is no wedding notice, no employment record, no obituary because nobody ever wrote one.
Everything else about Mary Davidson has to be reconstructed from the shape of the world she arrived into because the world she arrived into [music] did not consider her worth recording.
So consider the world.
She came to Canada in 1913, a year before the First World War, at the tail end of the great push of British immigration that had been filling the country for a generation.
She would have been a child through the [music] war and a teenager through the 1920s.
And then, right at the moment her adult life should have been beginning, the economy of the entire Western world fell in on itself.
By 1935, a quarter of the population of Toronto and its surrounding suburbs was on relief, 1 in4.
The marriage rate across the country fell by roughly 40% because people could not afford to start households.
And in 1930 and 1931, the federal government tightened the rules on who could enter Canada and deported something on the order of 25,000 unemployed immigrants.
People who had arrived exactly the way the Davidsons had arrived and who were now a budget line.
Somewhere in those years, Mary Davidson married a man named Andrew Lloyd Moffett.
They had one child together and then he left.
She was somewhere in her late 20s.
She had a child and the man who had been the household income was gone.
Here is what he left meant in Canada in the 1930s.
Because this is the machinery that made everything after it possible, and almost nobody knows it anymore.
Ontario had only had the power to grant a divorce in its own court since 1930, 6 years.
Before that, if you lived in Ontario and you wanted a legal end to your marriage, you petitioned the Parliament of Canada one marriage at a time by private statute, which was expensive enough that in practice it was a service available to wealthy people.
When Parliament finally handed the power to the Ontario courts in 1930, it also added desertion as a ground and told deserted wives that they could come to court and use it provided they had been separated from the husband for at least 2 years.
2 years plus the price of a lawyer in 1936 with a child in a city where one household in four was on relief.
For most women in her position, the law was not a remedy.
It was a waiting room with a fee at the door.
And on the other side of that ledger, for the man, there was almost nothing at all.
There was no national registry that would flag a man standing up in front of a minister to marry a second time.
There was no requirement that a husband tell any authority where he had gone.
There was no agency in the country whose job it was to go and find him.
So, the cheapest exit [music] from a marriage in 1936 was also the simplest one.
A man could walk out of a house, travel a few hundred miles, tell people he was single, and be believed because the only thing standing between him and a second wedding was the chance that somebody in the new town happened to know his face.
Andrew Moffett walked out, and at some point after that, Mary found out where he had gone.
Detective Constable Michael Kelly of the Toronto Police Service would summarize the next part 90 years later in six words.
She obviously came to Toronto.
If this is already sitting badly with you, hit the like button because that reaction is the only thing anyone gave her for 90 years, then stay with me because the next part is the part with almost nothing in it.
And I want to be honest with you about why.
There is no scene here.
There is no witness statement.
There is no timeline with clock times in it.
There is no neighbor who heard raised voices.
No landl.
No newspaper paragraph about a Scottish woman last seen on a particular street.
Every true crime instinct you have is reaching for that material right now.
And I am not going to give it to you because it does not exist and making it up would be the single easiest thing in the world to do.
Here is what does exist.
Police established that Andrew Moffett, having abandoned Mary, had married a woman in the Toronto area.
That second wife did not know there was a first one.
Mary came to Toronto.
And then, as Kelly put it, we surmised that some form of confrontation occurred which resulted in her death [music] and burial.
Investigators placed that at approximately April of 1936.
They got there from historical records, [music] from interviews with family members, and from what the burial site itself could tell them.
It is [music] an estimate built out of documents, not a date anyone wrote down at the time.
And there is one more thing the record establishes which is the [music] condition that made all of it possible.
The Danforth in 1936 was a young street.
The Blore Vioaduct had only opened in 1918 and before that there was no easy way to cross the Dawn Valley north of Gerard.
So the whole stretch [music] east of the river built up fast through the 1920s and kept building through the depression.
And what it built up into was an automobile street.
Ford put an assembly plant on the Danforth in 1921.
Garages, service bays, tire shops, and car lots ran along it for miles, and Robertson Motors was one of them, which means that on the Danforth in 1936, a man with a shovel behind a garage was the most ordinary site the street had to offer.
Ground got dug there.
Ground got filled, leveled, and paved there.
Nobody looked twice at turn soil behind a tire business because turn soil behind a tire business was what that street was made of.
What happened next is documented in detail because it happened in 1995.
Demolition workers at Danforth and Coxwell broke through the concrete floor of the automotive garage building on the Robertson Motors property.
And in the soil beneath that concrete floor, they found the skeleton of a woman.
The forensic examination put her between 20 and 30 years old at death.
Mary Davidson would have been 30 or 31.
And the examination established two things that decided everything afterward.
The first is that she had been intentionally buried.
That is a precise finding and it does a lot of work.
She was not dumped, not hidden under debris, not dropped into a hole that already existed.
Somebody made a decision, found a shovel and dug.
That takes time and it takes a place where you will not be interrupted.
And it means that whoever did it had access to that ground and confidence about that ground.
The second is the cause of death.
At least six blunt force injuries to the head from what the examiners described as a hammer-like weapon.
That is the phrase you use when the bone tells you exactly what a thing did and nothing at all about what the thing was.
The weapon was never recovered.
[music] It was never going to be.
Everything the ground had to say, it said in the first week, and then it stopped because a skeleton in 1995 could tell you a woman’s approximate age and how she [music] died and that someone had buried her on purpose, and it could not tell you her name.
For the next 31 years, she did not have one.
So, the city gave her a substitute.
They called her the Danforth Lady.
[music] If this case is getting under your skin the way it should, subscribe now because the next stretch is 31 years long and it is where most of the damage gets done.
Then we will come back to the man who dug the hole.
In 1995, police [music] did what you do when you have a face and no name.
They built the face.
We were unable to identify her at that time.
We created a composite image of [music] her, released it to the public in 1995, Kelly said.
The image went out to the media.
It went onto a Toronto Crimestoppers poster under the name the case had acquired, asking anyone who recognized her to call, and people did call, a lot of them.
We got a lot of tips come forward, a lot of people saying, “My mom, my aunt, [music] my sister went missing in the 1940s.
This could be her.
None of those ultimately panned out.
Read that again and notice [music] the decade.
The 1940s, every one of those families was working from the same assumption the investigation was working from, which was that a woman found under the floor of a mid-century car dealership had gone into the ground somewhere around the middle of the century.
That is a completely reasonable inference.
It [music] is the inference anyone would make.
This seemed small at the time, a working range rather than a conclusion.
[music] The kind of thing you write in pencil at the top of a file.
Mary Davidson had been in that soil since 1936.
Every family who picked up the phone was searching the wrong 10 years.
So, the tips came in and the tips were eliminated.
And the composite image of a woman who had never been photographed looked out of a poster at a city that did not recognize her because the people who would have recognized her were already dead.
The case was not forgotten.
On June 30th, 1998, the Discovery Channel Canada series exhibit A, Secrets of Forensic Science, hosted by Graham Green, devoted an entire episode to her, 23 minutes of national television.
They called it the Danforth Lady.
That episode is still watchable today, and [music] it describes her as a 50-year-old murder mystery, which tells you how the timeline was still being understood.
And then it went quiet for 24 years.
Now the structural failure in this case is not corruption and it is not incompetence.
It is something rarer and in some ways worse.
It is an [music] absence.
There was no missing person report to match her against.
There was no husband ringing a police station to say his wife had not come home.
There was no file anywhere in Canada with the words Mary Moffet and the word missing on the same page.
And the reason is the reason this whole case exists.
She was a married woman whose husband had deserted her who had then left wherever she was living in order to go and find him.
A woman who leaves to find someone is expected to be gone.
Whoever was waiting on word from her would have had every reason to assume she had found him or had not found him and had started again somewhere.
There was no system in 1936 that would have noticed the difference between a woman who moved and a woman who was killed.
You would think somebody eventually would have asked.
Nobody did.
So the file went dormant in a property room in a city that had built over her twice.
And the man who put her there had been dead since 1985.
Now, [music] pay close attention to this next part because it explains everything that happened after it.
Andrew Lloyd Moffett [music] did not run.
That is the thing to hold on to.
He did not flee the country in April of 1936.
[music] He did not go underground, change his face, live in a rooming house under a false name in a city where nobody knew him.
He stayed.
He married a woman in the Toronto area while he was still legally married to Mary.
And that second wife had no idea.
And in 1936, there was no mechanism on earth that was going to tell her.
And he went into business on the Danforth.
Police established that Andrew Moffett operated a tire business on the property adjacent to the one where Mary was buried.
Not in the neighborhood, not down the road, adjacent.
He ran a business and handled customers and made a living and went home at the end of the day next door to the ground he had put his wife into.
He did not go into hiding.
He went into inventory.
Think about what that takes.
Not nerve exactly.
Something flatter than nerve.
He had to drive past it and park beside it and order stock and pay rent and talk about the weather with whoever ran the garage next door.
Standing on ground he had dug himself and filled in himself.
From there, the pattern repeats.
Kelly told reporters that Moffett ultimately married four women and had children with three of them, four households, three sets of children.
And at some stage, he took a new name entirely, Drake Lloyd Cummings.
And under that name, he lived in the United States and he lived in Vancouver.
And in 1985, he died.
Run the arithmetic because the arithmetic is the whole act.
Mary Davidson was killed in approximately April of 1936.
Andrew Moffett died in 1985.
That is 49 years of ordinary life afterward.
49 years of marriages and children and moving vans and new cities under at least two names while she lay under a concrete floor a few feet from the tire shop.
And he died in 1985, which means he missed the demolition crew by 10 years.
He was never questioned.
He was never looked at.
Nobody ever knocked on his door because until 1995 there was no crime.
And until 2026, there was no victim.
Everything about him looked completely normal from the outside.
That was not a disguise.
That was the point.
Now, let me tell you about the 31 people.
In the summer of 2022, the Toronto Police Service counted up its open files of long-term unidentified human remains and narrowed the count to the cases where DNA material was still available to work with.
The number came to 31.
So they named the project after the number.
Project 31.
They describe it as a humanitarian initiative [music] and that word is doing real work because these are not cases that [music] make anyone’s numbers look good.
The project was built around 31 cases involving [music] in the service’s own phrase long-term unidentified deceased people for whom DNA material is readily available.
It was underwritten by a grant of $2.5 million from the Ontario Ministry of the Solicitor General, money earmarked specifically [music] for investigative genetic genealogy work.
The services homicide and missing persons cold case unit runs it.
Detective Sergeant Steven Smith oversees it.
Detective Constable Michael Kelly [music] and Detective Constable James Atkinson are among the investigators working the individual files.
Not all 31 need genealogy.
10 of them were resolved the straightforward way after the office of the chief coroner uploaded DNA profiles for the unidentified dead into the national DNA datab bank.
The national police database run by the Royal Canadian Mounted Police.
Sometimes a profile goes in and something comes back.
Genealogy is what you reach for when nothing does.
And it is the tool that has cracked six of the rest.
And when it works, this is what it looks like.
In 2021, human remains were found near Downsview Park in the north end of the city.
They belonged to Willard Du Duval, an indigenous man in his 70s who had been reported missing in 2018.
Genealogy led investigators to his niece Michelle Den, who is Onida [music] and who had an ancestry profile in a database for the oldest reason there is, which is that she had been looking for family.
When Toronto police telephoned her in January of 2026, she assumed it was a scam.
In 2008, a man was found dead under a subway bridge near Blur Street East and Parliament.
He was believed to be unhoused.
The man who found him was unhoused, too.
His death was not suspicious, and nobody could put a name to him for 17 years.
Genealogy eventually narrowed his origins to one specific region of Europe.
A bulletin went out to online community groups from that region, and he turned out to be a man from Portugal.
He was the ninth person project 31 identified.
His family were told and they were given the location of his grave.
Not one of those cases ended in an arrest.
That is not what the project is for.
The Danforth lady was selected in 2022 in the very first group.
Think about what that decision actually was.
In 2022, a Toronto detective looked at a file containing a woman killed before the Second World War [music] with no suspect who could be charged, no living witnesses, no possibility of an arrest, no chance of a trial, and no outcome that would ever appear in a clearance rate [music] and assigned at laboratory time and a genealogologist and a budget.
There was nothing at the end of that file except a name.
They sent it to Texas.
Anyway, if you have been on the fence about this channel, that decision is [music] why this one is worth your like.
Now, here is how they did it and how close it came to not working at all.
To understand what happened next, you have to understand what [music] investigative genetic genealogy actually is because almost everybody gets it [music] wrong.
Conventional forensic DNA is a lock and key.
You take a profile from your evidence, you compare it to profiles held in a police database, and either the key is already in the drawer or it is not.
For a woman who died in 1936, nobody’s key was ever in that drawer, and nobody’s key ever would be.
Every person who could have been a direct match to Mary Davidson died decades before the technology existed.
Investigative genetic genealogy does something structurally different.
Instead of looking for her, it looks for everybody who shares pieces of her.
You read hundreds of thousands of individual markers across the [music] genome, then compare that pattern against public genealogy databases [music] built by ordinary people researching their own families.
You are not looking for a match.
You are looking for third cousins and fourth cousins and the descendants of the descendants of somebody’s great aunt.
Then a genealogologist takes those scattered partial relatives [music] and builds family trees backwards until the trees intersect.
And the intersection is a person.
[music] It does not need her to be in a database.
It needs her family to have [music] kept having children.
And it is worth being clear about why the ordinary route was never going to work here.
The National DNA Datab Bank holds well over half a million profiles.
It is a genuinely large database.
It is also by design a database of people convicted of offenses [music] plus crime scene samples plus missing persons and the relatives who reported them.
Every one of those categories is made of people who existed inside a modern record system.
Mary Davidson left that system in April of 1936 [music] and never re-entered it.
You could have run her against every entry in that datab bank every day for 30 years and got nothing back because she was never the kind of person it was built to hold.
In 2022, Toronto investigators submitted the evidence to Oram, a private forensic laboratory in the Woodlands, Texas, which uses a process it calls forensic grade genome sequencing to pull usable profiles out of material that standard methods cannot touch.
The first submission failed.
There simply was not enough human DNA of sufficient quality in it to build a profile.
So the scientists went back to the skeletal remains and extracted again and again.
Each attempt recovered only small quantities of severely degraded human DNA.
Kelly explained why.
Because of the nature of how long the remains had been in the ground, some other bacterial issues and contamination, it made very difficult for us to get a good DNA sample to work with.
59 years in soil.
Every bacterium in that ground had spent six decades taking her apart and then they found the one piece that had held.
There is different parts of our anatomy which are more resistant to forms of bacterial contamination or degradation.
So, we were able to obtain a segment of bone from her that was actually able to yield a perfect, nice, clean, fully robust DNA profile for her.
One segment of bone.
After 90 years, after the hammer, after the grave, after the concrete, after the bulldozers, after 31 years in an evidence locker, there was still one piece of Mary Davidson that knew exactly who she was.
The usable profile was obtained in November of 2024.
Then the genealogologist took over, and the first thing the family trees told them was a direction.
The initial genealogy indicated Scottish ancestry originating in the Aberdine area, a laboratory in East Texas working from a fragment of bone out of a Toronto parking lot pointed at the county where she was born.
From there, it was follow-up investigation out along the branches [music] until it produced living people who might be related to her.
One of them provided a sample.
Other ran it through a rapid relationship test, comparing that relative’s profile directly against hers.
And on July 27th, 2026, the Toronto Police Service announced that the Danforth lady was Mary McCloud Moffett, born Davidson of Aberdine, Scotland.
Kelly’s summary of it was blunt.
Without investigative genetic genealogy, this never would have been solved.
Now, here is what a name buys you and what it does not.
There is no arrest in this case.
There is no charge, no arraignment, no courthouse, no judge, no jury, no verdict, and there never will be.
Andrew Lloyd Moffett died in 1985 and the law does not prosecute the dead.
What police did instead was name him publicly as the primary suspect in Mary’s homicide.
That is a police conclusion, and it is worth being exact about what stands behind it.
It rests on historical records, on interviews with family members, and on evidence recovered from the burial site.
It has never been tested by a defense lawyer.
No witness has ever been cross-examined on it.
Andrew Moffett was never questioned in his life about a crime nobody knew had happened, and he has no opportunity to answer it now.
Give that its full weight.
The April 1936 date is an inference.
The confrontation is, in Kelly’s own careful word, a surmise.
If this had gone to trial in 1937, it would have been a circumstantial case.
And then set beside it the things the circumstances do not explain away.
He abandoned her.
He married again in Toronto bigamously and kept it from her.
She came to Toronto looking for him.
She was buried deliberately with a shovel and ground immediately adjacent to the business he ran.
And he spent the rest of his life in two countries under another man’s name.
There is one more thing a name buys.
Police went and spoke to the families of the other three women.
We have been able to have discussions [music] with those family members as well.
Kelly said, “Obviously, this begins and ends [music] with a very sad, difficult tale to hear about.
But for some family members, it answers a few questions.
Some of those questions had been waiting a very long time to be asked.
The complication in this case [music] is not a corrupt prosecutor or a crooked lab.
It is the technique itself.
Investigative genetic genealogy works by reaching into genetic data that ordinary people uploaded [music] in order to find their own cousins and using it for a purpose those people did not have in mind.
That is not a fringe objection.
Ontario’s office of the information and privacy commissioner has issued formal guidance on police use of it and privacy advocates in Canada have been calling for firm guard rails around it for years precisely because it is so effective.
Both things are true at once.
The tool that raises legitimate questions about consent and genetic privacy is the same [music] tool that took a woman who had been an anonymous set of bones since 1995 and gave her back the name her mother gave her.
Neither of those facts cancels the other.
And anyone who tells you it is simple is selling something.
As for the other 30, as of April of 2026, 21 of the 31 people in Project 31 were still unidentified.
Investigative genetic genealogy had been the tool that cracked six of the solved ones.
And Mary was not alone on the day she got her name back.
The Toronto Police Service announced two identifications on July 27th.
The second was Paty Flora Lagard, whose badly burned body was found in the passenger seat of a car on Highway 401 on April 22nd, 2004, and who had gone unidentified for more than 20 years.
She was born in Ontario in 1962.
[music] Her parents came from Baron’s River, First Nation, and Long Lake, 58 First Nation.
She had two children.
Detective Sergeant Steven Smith of the Homicide and Missing Persons Cold Case Unit put it plainly, “After decades without answers, we have been able to restore the identities of Mary Davidson and Paty Lagard, provide information to their families, and uncover important facts about the circumstances surrounding their deaths.
Restore the identities, not solve.
Restore.
We opened on a concrete floor and a [music] date as though this were a story about a building.
It never was.
That floor was poured to make a patch of East Toronto ground.
Completely ordinary.
And it worked.
It worked for 59 years.
Cars sat on it.
A business ran above it.
Thousands of people crossed it without a thought.
Which is exactly what concrete is for.
But here is the other thing that floor did.
It held her in one place.
She was never scattered, never moved, never lost.
The thing that hid Mary Davidson from the world is the same thing that kept her whole enough that 90 years later, there was still one segment of bone in that ground that could say her name out loud.
She was born in Aberdineer, Scotland in 1905.
She was 8 years old when she stood on a ship and watched [music] Scotland go.
She grew up Canadian in the worst decade this country has had.
She was somebody’s daughter.
She was somebody’s mother once to one child.
Nobody wrote down what she did for a living.
Nobody wrote down what she looked like.
Which is why in 1995 a police artist had [music] to guess at her face and put the guess on a poster.
Nobody wrote down her voice or whether she still had Aberdine in it after 23 years in Canada.
She was 30 years old, maybe 31.
She found out where her husband had gone and she went there, which is the bravest thing in this entire story and nobody has ever written that down until now.
Her name is Mary McCloud Davidson and she deserves to be remembered for who she was, not just for how her story ended.
If she stayed with you, subscribe and send this to one person because [music] for 90 years, the total number of people saying her name was zero.
And that number only goes up if we keep saying [music] it.
We go again next week.
