Michael Cook, 39, was sentenced to 40 years in prison for the 2005 shooting at a South Phoenix mosque, Maricopa County Attorney Andrew Thomas announced Sunday.
Cook shot a mosque member who was working as a security guard when he was asked to leave the property on Oct. 18, 2005.
From his car, Cook shot the unarmed victim five times at close range and then fled the scene.
Cook believed his mother was being mistreated by the leadership at the mosque.
Cook was convicted on July 26, 2007, of attempted second-degree murder, drive-by shooting, five counts of aggravated assault, and misconduct involving weapons.
Cook was also sentenced for possession of marijuana for sale, a crime that happened after the shooting.
