TORONTO -- The man responsible for Toronto's deadly 2018 van attack is seeking to appeal his conviction on 10 counts of first-degree murder and 16 counts of attempted murder.

Alek Minassian filed a notice of appeal to Ontario's top court this week.

He argues, among other things, that the trial judge “misapprehended” expert evidence and made unreasonable findings of fact related to declining to find him not criminally responsible.

Minassian was sentenced last month to life in prison with no chance of parole for 25 years.

Eight women and two men died on April 23, 2018, when Minassian deliberately drove a rented van down a busy sidewalk.

Another woman died more than three years later from injuries suffered that day.
