A Camp Pendleton Marine was arrested Friday and another is sought in the killing of a fellow Marine found shot to death in an Orange County ditch last week, authorities said.
Lance Cpl. Christian Carney, 21, was removed from the camp's brig, where he was jailed Thursday night, and handed over to Orange County Sheriff's Department homicide detectives. He was arrested on suspicion of killing Pvt. Stephen Serrano, 20, a native of El Dorado in Northern California. Serrano was shot once in the torso.
Pvt. Alvin Reed Lovely, a 20-year-old Texas native suspected of being an accomplice, has been AWOL from his unit since April, said sheriff's spokesman John McDonald. He is believed to be driving a 2002 black Nissan Sentra and to still be in Southern California, McDonald said.
Investigators declined to give a motive for the killing, but McDonald said early speculation about a love triangle is not true.
