Ahmad Al Aliwi Alissa was convicted by a jury of 10 counts of murder at a Colorado supermarket. His defense team had argued he was mentally ill.

A jury has reached its verdict in the trial of Ahmad Al Aliwi Alissa, who is accused of killing 10 people in a March 22, 2021, massacre at a King Soopers grocery store in Boulder, Colorado. Alissa pleaded not guilty by reason of insanity to all charges.

The jury trial hinged not on whether Ahmad Al Alissa opened fire but whether the mentally ill man understood the difference between right and wrong.
