FLAGSTAFF, Ariz. - Coconino County Sheriff's Office deputies shot and killed an armed man in a standoff near Doney Park east of Flagstaff.

The man has been identified as 31-year-old Mark Nelson.

Police said Nelson's mother called 911 just before 10 p.m. Friday reporting Nelson was armed and suicidal behind the home.

Coconino County Sheriff's Office, Flagstaff Police Department and the Arizona Department of Public Safety all arrived at the area and tried to convince Nelson to surrender his gun, according to CCSO.

Police said Nelson drove his truck to the front of the home and got out of the truck with a high-powered rifle.

After more negotiation, Nelson pointed the gun at himself, then at officers, which is when CCSO deputies shot him, according to CCSO.

He was transported to Flagstaff Medical Center and pronounced dead.

CCSO said the shooting is under investigation by a multi-agency team.

This is the most recent in a series of officer-involved-shootings in the state.

Phoenix police officer David Glasser was shot and killed in the line of duty earlier this week.
