Alexandre Bissonnette, 27, was identified as the person who opened fire at the Quebec Islamic Cultural Center, according to a source with the Royal Canadian Mounted Police and a Quebec City court clerk.

Bissonnette faces six counts of first-degree murder and five attempted murder charges, according to the verified Twitter account of the Quebec Royal Canadian Mounted Police. He was a student at Laval University in Quebec City, according to the school.
Goodale, speaking to reporters at an Ottawa news conference, said the attack was one that would have been difficult to prevent. The terror threat level remains unchanged, he said. Witnesses said the mosque gunman fired indiscriminately into the crowd of worshipers, which included men, women and children.
Laval officials said they “strongly and unreservedly denounce the unacceptable and terrible acts” at the mosque.
Bissonnette, who was a student in the university’s school of social sciences, has been barred from any study or research activities until the end of the current judicial process, the school said.
