Police says a 21-year-old Arizona man fatally shot his father then turned the gun on himself after they argued about the son doing the dishes.

Mesa police found Aaron Farinacci (fehr-ihn-AH'-chee) blocks from his parent's house with a gunshot wound to his chest. He was in critical condition Tuesday.

Police say the incident began just after 6 p.m. Monday when Aaron Farinacci argued with his father, Jeffrey Farinacci, then ran into his parent's bedroom and locked the door. Jeffrey Farinacci got a key and unlocked the door, and his wife then heard two shots. She told police her son pointed the gun at her as she went to investigate.

Police say Aaron Farinacci had gotten his father's handgun from the nightstand.

Jeffrey Farinacci died at the hospital.
