An armed woman was shot and killed and a companion was wounded early Saturday during a confrontation with Tucson police officers answering a call from a woman threatening suicide, officials say.

The incident started about 1:15 a.m. when officers went to a house in the 2600 block of East Silver Street after a woman called 911 saying she had a gun and intended to commit suicide. She also told the dispatcher other people were with her in the house near East Grant Road and North Tucson Boulevard, Sgt. Chris Widmer said in a news release.

A woman holding a gun and a man were standing outside the front door when the first three officers arrived.

“As the officers made contact with them, the female brandished the gun. All three officers fired their duty weapons at the female,” Widmer said in the news release.

Both the woman and the man with her were struck.

The woman died at the hospital and the man was said to have injuries that are not life threatening. None of the officers was injured.

Both the shooting and the circumstances that led to the officers using their weapons is being investigated, which is standard procedure, Widmer said.
