A woman armed with a handgun was shot and killed by police and a companion was wounded early Saturday morning.

Tucson police officers answered a 911 call at about 1:15 a.m. from a woman who said she had a gun and intended to kill herself, Sgt. Chris Widmer, spokesman for the Tucson Police Department, said.

The woman, who was calling from a home in the 2600 block of East Silver Street near East Grant Road and North Tucson Boulevard, told the dispatcher other people were with her in the house, Widmer said.

Officers John Malovich, Alex Samorano and Jesus Maldonado were the first to arrive at the home and saw a man and a woman standing outside the front door.

“When the female observed the officers approaching, she removed a gun she had in a holster on her hip and began to raise the weapon up,” Widmer said. “She was given several commands to drop the gun, but she refused to comply. All three officers fired their duty weapons at the female.”

Both the woman and the man were shot by officers. They were transported to a local hospital where the woman, 24, died of her injuries. Her name has not yet been released.

The 27-year-old man suffered a non-life-threatening wound to his arm, Widmer said.

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

Malovich has been with TPD for 14 years; Samorano has worked for the department for five years; and Maldonado has been an officer for just over a year, Widmer said.
