KEY POINTS

  • Military police at Twentynine Palms Marine base in California responded to multiple shots fired on base grounds around 6:30 a.m. Tuesday
  • The base remained on lockdown for two hours as military police and base personnel searched for the shooter
  • The suspected shooter, said to be a marine, was hospitalized after he turned his gun on himself and sustained two self-inflicted wounds

A suspected gunman in an active shooter situation at the largest Marine base in the U.S. was hospitalized Tuesday for two self-inflicted gunshot wounds. The alleged shooter turned his weapon on himself after a two-hour-long standoff with military police and Southern California police.

Authorities have not released the name of the suspect but confirm he was a marine and that there were no other reported injuries.

The shooting unfolded at the Marine Corps Air Ground Combat Center, in Twentynine Palms, a city in San Bernardino County. Military police were notified of an active shooter on base grounds around 6:30 a.m. Tuesday after several shots were heard. The base entered lockdown and civilians were ordered to remain inside while police and base personnel searched for the shooter.

“Silence your cell phone. Run, hide, fight. Help is on the way,” an alert message to base residents shared on Twitter said.

Regular updates were also provided by the Marine Corps on Twitter.

The San Bernardino County Sheriff’s Department said it was notified of the active shooter situation shortly after the initial alerts went out. However, the base later told the department a shooting had taken place, but there was no active shooter.

“We have not been requested to assist them,” department spokeswoman Cindy Bachman told reporters around 8 a.m.
