New details are coming to light in the aftermath of the deadly shooting in Montreal that left three people dead in the city’s Côte-des-Neiges neighbourhood on Monday.
Here’s what we know.
Alleged shooter went to University of Lethbridge
The alleged shooter has been identified as Seth Scott Hatfield, a 25-year-old man from Lethbridge, Alta., according to the Quebec coroner’s office. The man’s name is the same as that which appears on a manifesto that was allegedly found inside a hotel room near the scene of the shooting.
In a statement, the University of Lethbridge confirmed that Hatfield was a student and that the university is cooperating with the police.
“Violence, such as the actions that occurred yesterday, has no place in our society. The University also strongly condemns the views and ideologies that have been attributed to the shooter in media reports,” the statements reads.
According to the university’s website, a student matching the name of the alleged shooter appears on the Dean’s honour list for philosophy for the winter 2026 program.
The coroner has also confirmed the identities of the other two people who were killed: 34-year-old Montreal police (SPVM) officer Mohamed Lamine Benredouane, of Laval, and Michel Mizrahi, 68, of Montreal, who was an innocent bystander.
The release of the names comes as CTV News confirms that Lethbridge police in Alberta are assisting the Quebec police watchdog, the Bureau des enquêtes indépendantes (BEI), in its investigation into the shooting.
Police also conducted a high-risk search of a home on Lemoyne Crescent in Lethbridge.
“As a precautionary measure, due to the possible presence of weapons, several neighbouring residences have been evacuated,” Lethbridge said Tuesday.
The police force also said it evacuated several neighbouring residences and was asking members of the public to avoid the area.
Provincial police working with BEI
Quebec provincial police are assisting the BEI in its investigation. The Sûreté du Québec (SQ) said it is conducting a criminal investigation into Monday’s events in relation to the shooter, including his movements, his motive, and the sequence of events that led to the tragedy.
An SQ spokesperson said their investigation is in its preliminary stages and did not have any public information to release on Tuesday morning.
The BEI, meanwhile, is leading the investigation into the actions of the Montreal police officers.
Slain officer hailed as a hero
The Montreal police officer killed in Monday’s shooting is being praised as a hero on Tuesday.
At a press conference on Tuesday morning, Stéphanie Valenzuela, the borough mayor of Côte-des-Neiges–Notre-Dame-de-Grâce, said Lamine Benredouane went to school in the neighbourhood that he served.
“Many of my friends many people in my network knew him personally so much to the point that this morning when I woke up, on my social media, there were flashback pictures of him from high school with close friends and family members, so it’s very personal. It hits very close to home and it’s just really devastating,” Valenzuela said, overcome with emotion.
“It was an act of heroism that I can’t highlight further and I just want his family and his loved ones to know that we are with them and we mourn with them.”
‘You can feel the pain’: Montreal mayor
Speaking at Tuesday’s press conference, Montreal Mayor Soraya Martinez Ferrada said she expressed her condolences to some officers who were holding the perimeter at the scene and that " you can feel the pain" they are feeling after the tragedy.
“Yesterday, people were in a mode of survival. Of course, you don’t feel that pain, but you feel it today. Some people didn’t show up at work this morning because they are scared, and we need to be there for all Montrealers,” she said.
Her priority over the coming weeks is to assure residents that Montreal is a safe city and that collectively, everyone needs to work together to prevent similar tragedies.
She also raised concerns about people becoming desensitized to violence after several videos showing graphic content from the shooting spread all over social media.
“How can we accept that?” the mayor said, following her tour of the community where the tragedy happened.
“As a society, we need to be respectful and make sure we are also prevailing around the dignity of the police officer that we saw yesterday, and the family that actually had to see those images.”
Pornhub parent company releases statement
On Tuesday, some windows were still shattered at the offices of Aylo, the parent company of Pornhub and other major pornography brands.
The manifesto that was found in a nearby hotel room that bears the same name as the alleged shooter attacks the porn industry, likening pornographic content to a twisted substitute for real intimacy. The document frames watching pornography as an activity done in isolation because certain men are otherwise excluded from romantic and sexual partnerships.
In a statement issued on Tuesday, Aylo expressed its condolences to the victims.
“Although our city has been struck by this tragedy, we would like to express our gratitude to the emergency services who courageously protected us and ensured that none of our staff were physically injured during yesterday’s events,” the company said.
It added that it was aware of media reports suggesting a possible link between the shooting and Aylo and Pornhub.
“The investigation is ongoing; we will not speculate on the motives nor disclose any unconfirmed information,” the company added.
