The killing Monday angered and saddened Passmore’s family and raised questions about whether officers could have done things differently. It came as many police departments nationwide have changed the way they respond to certain calls, including those involving mentally ill people — in response to outcries over police killings.

Police body camera videos showed part of what happened after officers arrived at Passmore’s home in Wallingford, Connecticut. The man’s girlfriend had called 911 shortly after 2:30 a.m. to report he had shot himself in the face in their bedroom.

The state inspector general’s office, which investigates all police shootings in Connecticut, said the officers spoke to Passmore for about nine minutes.
