TACOMA, Wash. -- Tacoma Police Department officials say a robbery suspect was fatally shot by an off-duty officer Wednesday night.

Spokesperson Loretta Cool said the off-duty officer was driving when he spotted a woman being robbed at S. 56th and S.Tacoma Way. The officer stopped, got out of his car, and notified the robbery suspect he was an officer.

Cool says the suspect ran from the scene around the corner, where his truck was parked. When citizens nearby tried to stop the suspect, the suspect pulled out a gun and the citizens backed away. At that point the officer caught up to the suspect and again identified himself, but the suspect didn't stop. The officer fired one shot at the suspect when the suspect was inside his truck.

The suspect managed to drive around the corner before stopping his vehicle at S. 56th and S. Tacoma Way. He was transported to a hospital. Tacoma police later confirmed the suspect died.

"Someone lost their life over a cell phone. I don't understand why people are doing the things that they are doing," said an onlooker.

Reverend Abigail Vizcarra Perez was at a coffee shop when she heard a woman, the robbery victim, scream.

"Everybody just really wanted to help, and we really didn't want it to end this way," said Vizcarra Perez. "I am feeling sad for the officer, for the young man's family, and that girl."

The robbery victim was not seriously hurt.

The Pierce County Medical Examiner's Office identified the man as Jason Galvaiz, 40.

The off duty officer is on standard administrative leave.
