DENVER—Rejecting an insanity defense, a Colorado jury on Monday convicted a man diagnosed with the severe mental disorder schizophrenia of first-degree murder in a 2021 mass shooting at a grocery store in the city of Boulder that killed 10 people including a police officer.
Ahmad Al Aliwi Alissa, 25, had pleaded not guilty by reason of insanity. The jury instead found the Syria-born man, guilty in Boulder District Court on 10 counts of first-degree murder.
