Authorities say a fight led to one roommate shooting another Sunday at a home near Phoenix. 

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.

Officers responded and took Penton into custody without incident.

Garofalo was pronounced deceased on scene.

Just two days before the murder, Penton appears to have posted a threat on a social media account connected to his name.

Gilbert police said while they cannot confirm the account is Penton's, they "are looking into the possibility."

Penton has been arrested and was booked into Maricopa County (Arizona) Jail on murder charges.

Police are still investigating what exactly happened the moments before the shooting.
