Thursday, December 11, 2008, Catherine DAVIAU 27 years old, a young woman without history was found dead in her apartment in the Rosemont neighborhood during an intervention of the Montreal Fire Department at her home located on 5th Avenue following a call to the "911" of a neighbor who had noticed the fire. Following the discovery of the body, Montreal firefighters appealed to the SPVM. During the stage cover, the police quickly realized that the young woman had been murdered. Catherine DAVIAU was found on the bed of her room, she bore signs of violence. The investigators of the Major Crimes section of the SPVM suspect that the attacker started the fire to hide his crime.

During the investigation, the police learned that that day Catherine DAVIAU had worked all day in a company on the West Island of Montreal as she has done for a few years. After her shift at around 4:30 pm, she left her job and drove home on the highway 40 to East. Given the heavy traffic on that day, police believe she would have arrived home about an hour later. The investigation also revealed that the victim had used his cell phone shortly after 5:30 pm to communicate with an acquaintance.

A neighbor called the "911" around 7:07 pm. When the firefighters arrived all the exits were closed and locked, suggesting that the victim had let in the attacker and that there had been no escape. 'breaking in.

Given the likely arrival of the victim at home and the time of the "911" call, the aggressor's window of opportunity was a little over an hour .

As part of the SPVM investigation for several years, the family, neighbors, friends and acquaintances Catherine DAVIAU were met by the police, but, to date, no solid line of inquiry has been identified to elucidate the gratuitous murder of this young woman without history, brutally assaulted, inside her home in the Rosemont neighborhood

Cold case: Police hope public can help them solve 2008 murder | CTV News
''Montreal police are asking for the public's help to solve a cold case.

In December 2008, while investigating a fire in Rosemont, police found the body of 26-year-old woman Catherine Daviau inside.

The fire had broken out in Daviau’s home in a triplex on 5th Ave. near Masson St.

Her body showed signs of violence and that she was sexually assaulted.

They suspect the killer tried to hide the murder by lighting the apartment on fire.

Police now believe whoever committed the crime knew Daviau and let them into the apartment because there were no signs of forced entry.

The attack occurred shortly after she would have gotten home from work.

Police say they found some DNA at the scene, but were unable to match it with anyone in their DNA bank.''

Does anyone know of the DNA banks are country specific? Montreal isn't that far from the US border - I wonder if it would match a US DNA sample.

''The Montreal police department has also tried phenotyping twice, which can take an unknown suspect's DNA and use it to predict their ancestry and physical traits such as hair, eye and skin colour.

In 2018, the SPVM tested DNA evidence found at the apartment of Catherine Daviau to develop a composite photo of what the suspect might look like.

The 26-year-old was sexually assaulted and killed in her Rosemont apartment in December 2008. The assailant then set her apartment on fire. The photo was shared with Daviau's inner circle but not made public. The case remains unresolved.''

The two cases the SPVM had phenotyped were outsourced to American companies, but Quebec's forensic lab says it will be able to do testing in-house next year.'

Does anyone know of the DNA banks are country specific? Montreal isn't that far from the US border - I wonder if it would match a US DNA sample.

This 48 year old cold case is very recent, the perp is from the US and that is where his grave was located and disturbed to get his DNA.

Meurtres non résolus: le SPVM annonce qu'il possède de l'ADN dans deux dossiers

'On their new page of unsolved murders, Major Crimes investigators also recall the circumstances of the murder of Catherine Daviau committed in her apartment on5th Avenue, in the Rosemont district in December 2008. The 27-year-old woman was sexually assaulted and murdered, before the suspect tried to cover up the crime as arson. The police had already announced that they had the killer's DNA.

"These are cases with very strong physical evidence. We think we can solve them, we just don't have the names that go with them. We just need to get out the lucky number that will allow us to make a match. We are just missing the last piece of the puzzle," says Commander Rozon.

Investigators involved in the various unsolved murder cases will soon post videos on the SPVM website.

All the families of the victims have been notified and have given their consent.'

''Montreal police say they’ve solved the cold case of the 2008 murder of Catherine Daviau.
At a news conference Wednesday afternoon, police said it was Jacques Bolduc who killed Daviau Dec. 11, 2008 in her Rosemont—La Petite-Patrie apartment. Daviau was 26 years old.''
''Bolduc and Daviau didn’t know one another before the crime, Dupont said. His name had never come up in investigations before the laboratory finding.
Since Bolduc is dead, no trial will take place.''

Montreal police solve 2008 cold case murder of Catherine Daviau, using genetic genealogy to ID killer

Montreal police have solved a nearly 17-year-old cold case. The SPVM announced Wednesday that they solved the murder of Catherine Daviau, a 26-year-old woman killed in her home in the Rosemont–La Petite-Patrie borough in Dec. 2008. Police say the DNA of Jacques Bolduc, who died of natural causes...

''Police confirmed Bolduc was not a relative of the victim and he reportedly contacted Daviau a few days before the murder, after she had listed her car on an online classifieds site.''

have they said what he was in prison for?

From the article:

“Police say the DNA of Jacques Bolduc, who died of natural causes in 2021 at the Archambault Institution, where he was serving a sentence for two robberies and attempted murders, matches that of what was collected on the scene.”

Catherine Daviau was found dead in her Rosemont apartment in December 2008. Seventeen years later, through genetic genealogy, Montreal police say they solved the cold case. Police say the murderer was Jacques Bolduc, a man who died in 2021 at the Archambault Institution in Sainte-Anne-des-Plaines, Que., where he was serving time for other crimes.

Criminal Jacques Bolduc
'He has already taken a child hostage with a gun, stolen a truck to escape from the penitentiary and shot three innocent people, two of whom were shot in the head and miraculously survived. A violent recidivist deemed irredeemable, Jacques Bolduc has just been sentenced to an extremely rare indeterminate sentence, reserved for the worst criminals in the country.'

''According to the Crown psychiatrist, Dr. Louis Morissette, the offender has an antisocial personality disorder with narcissistic traits and possibly borderline traits. He does not suffer from any mental illness and is not a psychopath.''

 

[AndrewM71]

So he was in prison for attempted murder but his DNA wasn’t on file? I thought providing a sample was a standard component of any sentence for a violent crime.

''Suzanne Marchand, director general of the Laboratoire de sciences judiciaires et de médecine légale, Quebec's forensic lab, said they were able to build a DNA profile of a male suspect in 2008 but it didn't match any profiles on the national genetic database.
Over the years, more than 100 DNA samples were analyzed and compared to Bolduc's. Marchand said they began searches in genetic genealogy in 2021.

In August 2025, the lab was able to scientifically confirm that the DNA collected at the crime scene was that of Jacques Bolduc.''
