Man who warned Twitter he might kill his roommate is arrested two days later for murder

An Arizona man who tweeted about killing his roommate was arrested two days later, after allegedly murdering the other man. Police said 21-year-old Zachary Penton called them on Sunday to say he had shot his roommate after an altercation at the home they shared in Gilbert, a Phoenix suburb.

Penton was taken into custody and booked on murder charges at Maricopa County Jail. The victim, 41-year-old Daniel Garofalo, was pronounced dead at the scene. Officers also recovered the handgun thought to have been used in the shooting. With the investigation ongoing, attention has focused on a Twitter account apparently attributed to Mr Penton.

On Friday, the 21-year-old wrote that he might “viciously murder” his roommates unless he moved out of the home. In a separate post, he suggested that at least two of the people he lived with had got into a drunken brawl after one of them was stung by a bee.

Police told ABC15 they were “looking into the possibility” that the Twitter account did indeed belong to Mr Penton.
