A Tucson man is being held on $750,000 bond in connection with the stabbing death of his father Friday night on the city’s southwest side, officials said.

Brian Gene Harmon, 32, is accused of stabbing to death Phillip Harmon, 56, said Deputy Dawn Barkman, a spokeswoman for the Pima County Sheriff’s Department.

Deputies from the Green Valley District responded Friday to a 911 call from a house at 6404 W. Pinto Road, Barkman said. A member of the Harmon family had called the emergency line to request an ambulance following an altercation, she said.

When officials arrived they found Phillip Harmon dead outside his house and discovered that Brian Harmon had left the scene, Barkman said.

Witnesses said Brian Harmon and his father had been involved in a physical altercation, Barkman said in a press statement.

Pima County Sheriff’s deputies arrested Brian Harmon on Saturday, when he returned to the West Pinto home, Barkman said. He was charged with first-degree murder and failure to comply with a court order related to a charge of driving under the influence in Nogales, Ariz.

The police do not have a motive for the stabbing, Barkman said.
