21-year-old Zachary Penton has been arrested after telling police that he shot and killed his 41-year-old roommate, Daniel Garofalo, in Arizona.
According to Penton’s call with police, the shooting occurred after the two were involved in a dispute. When police arrived, Garofalo was pronounced dead on the scene.
Upon further investigation, officials found out that this murder came two days after Penton allegedly posted a threatening message to his Twitter account.
“I need to move out of my place before I viciously murder my roommates,” wrote Penton.
Police have still not verified whether or not the tweet was sent from Penton. This tweet, as well as other tweets that speak to the living situation with his roommate, have since been removed from his account.
Penton and Garofalo lived together for two months before the shooting occurred. Penton, who did not personally know Garofalo, moved into the 41-year-old's home. Penton said to police officials that Garofalo often made deadly threats.
According to an official record documenting the incident, “Zachary stated the homeowner entered Zachary's bedroom, told him he was going to kill him if Zachary did not move out of the house and tackled Zachary to the bed.”
During the scuffle, Penton grabbed a Glock 17 that he owned and kept under his bed. He fired it at Garofalo and hit him in the chest. However, police also noted that it appeared that Garofalo also suffered one gunshot wound to the head.
Before this incident, Penton made several Twitter posts about guns and weapons in general.
Penton is being held at the Maricopa County Jail on a $750,000 bail.
