TWENTYNINE PALMS, Calif. (AP) — The U.S. Marine Corps says a person who was surrounded by military police responding to reports of an active shooter on a California Marine Corps base has suffered a self-inflicted gunshot wound. Spokeswoman Capt. Nicole Plymale says no one else was injured early Tuesday at the Marine Corps Air Ground Combat Center in Twentynine Palms. She says shots were reported on the base around 6:30 a.m. and military police cordoned off the area about two hours before the person fired the shot and was transported to a medical facility. The vast Twentynine Palms base is located in the desert 125 miles east of Los Angeles.
