POWAY, CA — An 18-year-old wanted for various weapons violations in San Diego County was arrested Saturday in Oklahoma, authorities said.

Cameron Johnson fired a rifle in an open field Tuesday near Hidden Valley Drive and Birch Lane in Poway, according to the San Diego County Sheriff’s Office. Johnson, who was dressed in military-style fatigues, was in possession of a rifle that did not have a serial number when he was contacted by deputies.

“At this point, Johnson ran from deputies into an area with dense vegetation,” sheriff’s Lt. Colin Hebeler said. “Despite an hours-long search involving deputies, sheriff’s ASTREA (helicopter) and sheriff’s K-9s, Johnson was not located.”

Deputies found firearm parts without serial numbers and body armor when they served a search warrant at Johnson’s home, Hebeler said.

Johnson was wanted on suspicion of negligent discharge of a firearm, possession of an un-serialized assault rifle and violation of a gun violence restraining order, Hebeler said. The San Diego Superior Court issued a warrant for his arrest Thursday.

Johnson was located and arrested Saturday in Oklahoma City. He is expected to be booked into Oklahoma County Jail and returned to San Diego, Hebeler said. He is expected to face charges of illegal possession of an assault weapon and six counts of illegally possessing a firearm, ammunition, gun parts and magazines in violation of a gun violence restraining order.
