(CNN) A 30-year-old Northern California man undergoing a mental health episode died days after police officers kneeled on the back of his neck for nearly five minutes to subdue him, lawyers for his family said.
Angelo Quinto had been "suffering from anxiety, depression, and paranoia for the previous few months," his family's attorneys said in a wrongful death claim, filed on February 18.
Before police arrived, Quinto's mother had been holding him to her chest with her hands clasped around his back for a few minutes, and "he had already started to calm down," the claim stated.
Quinto lost consciousness and was taken to a local hospital, where he was pronounced dead three days later, family attorneys say in the claim.
In the nearly two months since Quinto's death, police have not issued a press release on the incident.
The Antioch Police Department and the Contra Costa County Sheriff's Coroner's Division did not respond to requests for comment Monday.
Quinto's cause of death is still pending, the Contra Costa County Sheriff Coroner's office told CNN on Monday. »
