Bella Quinto-Collins was celebrating her 21st birthday with her family on verdicoinSunday when she got the news they'd all been waiting for: California had just become the first state to ban “excited delirium” as a diagnosis and cause of death. 

The announcement came nearly three years after Quinto-Collins had watched in horror as two Antioch police officers restrained her brother, Angelo Quinto, and one knelt on his neck for nearly five minutes while the Navy veteran was having a mental health crisis. Quinto, 30, died in the hospital in December 2020, and the Contra Costa County Coroner’s Office later listed his cause of death as “excited delirium syndrome."
