The 29-year-old gunman who was identified as Faisal Hussain was behind an attack that killed two people and injured 13 others in Toronto. He suffered from psychosis and depression, his family has said. He died on Sunday after a brief exchange of gunfire with the police.

“Our son had severe mental health challenges, struggling with psychosis and depression his entire life,” his family said in a statement to CBC News. The family also said that the interventions of professionals were not successful.

Hussain's family expressed condolences to relatives of the victims and said it was "utterly devastated" by the loss of life.

Woman and girl dead, 13 other people injured

The Ontario Special Investigations Unit (SIU), which looks into incidents involving police which result in death, said a post-mortem examination on the suspected shooter is scheduled for Tuesday. The suspect, armed with a handgun, opened fire at 10 p.m. on Sunday on a stretch of Danforth Avenue filled with restaurants and family-friendly attractions in an area of east Toronto known as the Greektown neighborhood, the SIU said.

A 10-year-old girl and 18-year-old woman have been confirmed dead and 13 others are injured after the killer mowed people down with a handgun in the Canadian city. Local politician Nathaniel Erskine-Smith confirmed the 18-year-old victim was Reese Fallon, a recent high school graduate who planned to study nursing.

The rampage came just three months after a van struck and killed 10 people in Toronto in an apparent attack directed toward women.

"We do not know why this happened," Toronto police chief Mark Saunders told the reporters on Monday, adding he would not speculate about the gunman's motive.

"It's way too early to rule out anything."

Toronto International Film Festival event canceled

“In light of the tragedy that occurred last night in Toronto and out of respect for those affected, TIFF is canceling its scheduled press conference tomorrow, July 24th,” TIFF brass said in a statement.

“Instead, the film announcements will go out via press release at 10 am. The Toronto Danforth area is the gold standard of our city’s vibrancy and we stand with our fellow Torontonians in condemnation of this violence.”
