A 46-year-old man died Friday in an officer-involved shooting in Mesa, police said.

Police responded just before 5 p.m. Sept. 29 to the 1000 block of East 9^th Drive to a report that a man was trying to kill himself.

A caller phoned police to let them know the man was in a running vehicle with a hose attached to the tailpipe. Fumes were filtering into the car.

The caller detached the hose, and the man got out of the car, police reported.

Officers arrived and tried to talk to the man, but they said he refused and showed them a knife.

“He began walking towards officers and refused to stop. This is when the officer-involved shooting occurred,” police said in a release.

Life-saving measures failed, and the man was pronounced dead.

Four officers were involved, and none of them were injured.
