A man turned himself in to Tucson police detectives Friday afternoon at his attorney's office in connection to a shooting at a west side bar.

Mark Walck, 51, was arrested and faces three counts of aggravated assault, said Sgt. Chris Widmer, a Tucson Police Department spokesman. He said the gun used in the shooting also was recovered at the attorney's office.

Walck was booked into the Pima County jail.

Officers were called just before 12:30 a.m. Friday to Famous Sam's, 2320 N. Silverbell Road, near West Grant Road, where they found a man with multiple gunshot wounds, said Widmer.

The man was taken to a local hospital with life-threatening injuries.

Widmer said Walck and a friend became involved in a fight with the victim. He said during the fight Walck pulled out a handgun and shot the victim.

Walck ran away and left his vehicle at the restaurant and bar, said Widmer.
