Alexandre Bissonnette watched videos of mass murders before Quebec City mosque attack, court hears

The man convicted of killing six men inside a Quebec City mosque on Jan. 29, 2017, spent hours searching online for videos and references to mass murders in the weeks before he gunned down the worshippers, it was revealed Friday at a court hearing.

Alexandre Bissonnette, 28, also entered online search terms for mass murderer Dylann Roof 201 times between Jan. 1 and Jan. 29, 2017 — the day of the attack. Roof killed nine people at a South Carolina church in 2015.
