A California Navy veteran died after a police officer knelt on his neck for nearly five minutes in December 2020, his family alleges in a lawsuit.

The sister of Angelo Quinto, 30, called law enforcement on Dec. 23 after he was purportedly experiencing a mental health emergency, according to a lawsuit filed by the family against the city of Antioch, California. A pair of officers restrained Quinto, placed him on the floor, and one of the policemen knelt on his neck for around five minutes while the veteran “started bleeding from his mouth,” the suit alleged, adding that “at no time while being restrained did Mr. Quinto resist physically or verbally.”
