Twentynine Palms: Person hospitalized with self-inflicted gunshot wound after reports of active shooter at base, Marines say

TWENTYNINE PALMS, Calif. (KABC) -- A person was hospitalized with a self-inflicted gunshot wound Tuesday morning after military police responded to reports of a possible active shooter at the Marine Corps Air Ground Combat Center in Twentynine Palms, the Marine Corps said.

"The individual is currently being treated and will be transported to a medical facility," the Marines said in a statement. Whether the unidentified person is a civilian or member of the military is unclear.

No other injuries were immediately confirmed as a shelter-in-place order was lifted at the sprawling base in San Bernardino County.

Gunshots were reported about 6:30 a.m. and the area was cordoned off, the news release said. The self-inflicted gunshot wound occurred about two hours later.

Before the person was hospitalized, a spokesperson for the San Bernardino County Sheriff's Department said in an email to ABC7: "It's my understanding there is an incident they are working and they are not requesting our assistance," referring to the Marines. The sheriff's spokesperson said he was told by the Marine Corps that "it's not an active shooter."

An investigation is underway.

About 8,500 people live on the massive base that covers 600,000 acres.
