Family had called Antioch, California, police to help with Angelo Quinto's mental crisis and erratic behavior.
CASSANDRA QUINTO COLLINS: What-- what-- what happened?
CAT SANDOVAL: In California, 30-year-old Navy veteran Angelo Quinto's handcuffed body lies lifeless in a pool of blood.
CASSANDRA QUINTO COLLINS: I-- not that I know of. Come on, go and take him. Take him, please.
- Use the Narcan?
CASSANDRA QUINTO COLLINS: Please, please.
CAT SANDOVAL: His mother begs the officers and paramedics to get him the medical help he needs.
ISABELLA COLLINS: There's no good reason why he is not alive today.
CAT SANDOVAL: The family has filed a wrongful death claim, saying Antioch, California police officers put a knee to Quinto's neck for nearly five minutes. He died in the hospital three days later.
CASSANDRA QUINTO COLLINS: I just trusted them so much, that even to this day, you know, I feel so guilty.
ANGELO QUINTO: Trying to keep my mind clear, trying to keep myself healthy.
CAT SANDOVAL: In December when his sister Isabella Collins called 911 to help deal with Quinto's mental crisis and erratic behavior, she didn't expect this.
CASSANDRA QUINTO COLLINS: Oh, my god.
- How could this happen to somebody who did not resist, did not pose a danger?
CAT SANDOVAL: Quinto was taking modafinil, which helps with sleep disorders. The Antioch Police Department has yet to release an official cause of death, or the names of the officers involved. They didn't respond to Newsy's requests for comment, but the family's private autopsy suggest the cause of death was asphyxiation.
BEN NISENBAUM: It's hard to believe that they used it In this case after George Floyd, or that any officer would use it. You think that every police department would tell their officers never do this.
CAT SANDOVAL: Quinto's family describes him as a creative artist, but they now hold guilt over whether they should have called 911 and trusted the cops in the first place.
ANGELO QUINTO: I don't think people understand that I'm just pretty damn normal.
CASSANDRA QUINTO COLLINS: I lost a child, and now I have this other kid who is suffering, and who is blaming herself for what had happened.
CAT SANDOVAL: Before the officers arrive, Cassandra Quinto Collins and said she was holding her son in a bear hug to calm him, and then officers took over. Quinto's final words were to the officers, "Please don't kill me." For "Newsy," I'm Cat Sandoval.
