The alleged shooter in Montreal on Monday has been identified as Seth Scott Hatfield, 25, from Lethbridge, Alta.
His name was released by the Quebec coroner on Tuesday, a day after he allegedly exchanged gunfire with police outside a Hilton hotel in the Côte-des-Neiges district.
The coroner has also identified the two other people killed — Mohamed Lamine Benredouane, 34, a Montreal police officer, and Michel Mizrahi, 68, a bystander caught in the crossfire.
Montreal police Chief Fady Dagher says officers were met with gunfire after responding to a 911 call Monday morning about a person with a gun at the hotel. Witnesses described hearing up to 40 gunshots.
Lethbridge Police said Tuesday morning they were conducting a high-risk search at a home along Lemoyne Crescent.
The police force also said they had evacuated several neighbouring residences and were asking members of the public to avoid the area due to the possible presence of weapons.
Multiple Quebec media have reported that the gunman wrote a manifesto, which they said expressed hatred toward women and calls for more violence.
As well, a police spokesperson in British Columbia has said police forces across that province were warned of the possibility of an anti-police manifesto linked to the Montreal shooting. Staff Sgt. Lindsey Houghton with the Surrey Police Service said the information was issued Monday afternoon by an intelligence-sharing unit operating out of the RCMP B.C. headquarters.
On Tuesday in the Côte-des-Neiges district, some members of Montreal's Jewish community gathered around the scene of the shooting to mourn Mizrahi, who was working in a nearby business. Local residents appeared to be visibly shaken and emotional, as police maintained a perimeter around the crime scene.
Stuart Nutik, who lives nearby and is a member of the Jewish community, said he was at home when a neighbour warned him there was an active shooter near the synagogue he attends.
"I couldn't believe it," he said. "Thank God my friend told me, so I stayed home."
Nutik described the shooting as a tragedy and said the neighbourhood was struggling to process what had happened. "For the whole community this is not normal," he said. "It's a tragedy. I hope God will give strength to the people involved."
Another local resident, Lia Gunthridge, said she was pushing her three-year-old son in a stroller near a playground in the park near where the shooting took place, when she heard gunshots.
"We like to go there to relax. It's such a nice space," she said. "But we left quickly when we saw the police. It didn't seem safe."
She returned Tuesday morning without her son to pay her respects to the victims. "Knowing that such a tragedy took place so close to where I play with my child, it just feels too close," she said.
Quebec's police watchdog is investigating the shooting, while Quebec provincial police have launched a parallel criminal probe.
Montreal Mayor Soraya Martinez Ferrada also visited the neighbourhood on Tuesday, saying that Montrealers should feel safe in their city, despite the tragedy.
