Man arrested for fatally shooting roommate after fight: Gilbert Police 08/22/2016 3:54 pm PDT Comments KNXV via KNXV: GILBERT, Ariz. -- (KNXV) -- Authorities say a fight led to one roommate shooting another Sunday at a home near Chandler Heights and Higley roads. Officers say 21-year-old Zachary Penton called police and told them he shot his roommate, 41-year-old Daniel Garofalo, after some sort of altercation. Garofalo was pronounced deceased on scene. Penton was taken into custody without incident. He is being held on suspicion of second-degree murder. Just two days before the murder, Penton appears to have posted a threat on a social media account connected to his name. "I need to move out of my place before I viciously murder my roommates," Penton allegedly posted on Twitter the night of August 19. Gilbert Police said while they cannot confirm the account is Penton's, they "are looking into the possibility." Bond was set at $750,000 for Penton at his initial court appearance Monday. Penton told police he scuffled with Garofalo after being told to move out and he feared for his safety before shooting him.
