Police have arrested an 81-year-old Southern California man, Prince King, who they allege has been a “serial slingshot shooter” victimizing his neighbors for nearly a decade.

Azusa police responded to a “quality of life issue” on North Enid Avenue and discovered that dozens of residents had been targeted by a slingshot shooter over the past nine to ten years. King allegedly broke windows and windshields, and nearly hit people with his slingshot.

Police executed a search warrant at King’s home on Thursday, finding ball bearings and a slingshot, and subsequently arrested him. According to Lt. Jake Bushey of the Azusa police, the investigation began after the first slingshot incident but only recently identified King as the suspect. Detectives linked most of the ball bearings to King’s backyard or a nearby neighborhood.

Police have not identified a motive beyond “malicious mischief.” While the shots were not random, the specific targets remain unclear. Some commenters on the police department’s Facebook post reported their car windows being shot out but couldn’t confirm if King was responsible.

King’s next court date is scheduled for Tuesday.
