Authorities were looking for a shooter in Tempe on Sunday morning northeast of Mill Avenue and Baseline Road.
No suspect information was immediately available as residents were asked to remain indoors while police on foot and in the air searched the area throughout the morning.
At about 4 a.m., officers were patrolling near Second Street and Minton Drive when they heard multiple shots fired and found a man in a backyard who had been shot and killed, said Tempe police spokeswoman Detective Lily Duran.
People were inside the home when the shooting occurred and told police that the shooter had fled the area on foot, Duran said.
It was not clear if the shooter was alone, or the relationship between the shooter and the victim.
The Maricopa County Sheriff’s Office was asked to assist with a helicopter, along with a K9 unit from Tempe police, Duran said.
Anyone with any information on the shooting or anyone who sees or hears anything suspicious is asked to call 911.
