Diana Showman was 19 and living in San Jose, California, when she died on the morning of August 14, 2014. Diana, who had bipolar disorder, made a 911 call saying she had an Uzi and threatened to harm her mother and brother if police did not respond. She was alone in the house and not armed with a firearm; she was holding a spray-painted power drill that resembled a gun.

Officers arrived and ordered her to drop the object. The county District Attorney cleared Officer Okuma, finding she reasonably feared for her life and did not know the object was a drill. Diana’s parents, Jim and Vickie Showman, disagreed with that conclusion and pressed for better crisis-intervention training.

The family later reached a settlement with the City of San Jose focused on improving police training and response to mental-health crises rather than on monetary compensation, and they have since worked to advocate for non-lethal options and improved dispatcher-officer communication. Does anyone have information about Diana’s case or the reforms that followed?
