A 30-year-old Antioch man died after an officer pressed his knee on the back of the man’s neck while he was suffering a mental health crisis, family members told KTVU Wednesday.

The family of Angelo Quinto is planning to file a legal claim against the Antioch Police Department on Thursday, following the Dec. 23 episode that left Quinto unconscious and bloody. Quinto was pronounced dead at a hospital three days later.

"He said ‘Please don’t kill me. Please don’t kill me,’" Quinto’s mother, Cassandra Quinto-Collins told KTVU, describing her son's last words. "I was there. I was watching them. I trusted them. I though they know what they’re doing."

The family is searching for answers as police are under heightened scrutiny around the nation, following high-profile killings like the death of George Floyd, who died after an officer in Minnesota put his knee on Floyd’s neck.

Antioch police have released almost no information about the case. In a statement Thursday, Lt. John Fortner said the investigation is still open.

He said the department is working with the local district attorney’s office and the coroner’s office.
