A 14-year-old girl with a learning disability went missing. Military police found her in Camp Pendleton barracks 2 weeks later.

• A 14-year-old girl went missing on June 9 and was later found by military police in Camp Pendleton barracks.
• Military authorities and a human-trafficking task force are now investigating the case.

A 14-year-old girl whose family says she has a learning disability went missing for two weeks until she was discovered by military police at the Marine Corps base Camp Pendleton, according to the San Diego County Sheriff's Department.

Military authorities have since taken an active-duty Marine with Combat Logistics Battalion 5 into custody, a military spokesperson confirmed to KTLA. San Diego's human-trafficking task force is also investigating the incident, along with the Naval Criminal Investigative Services, the sheriff's department told Insider in a statement.

It's unclear if that Marine has been criminally charged or released from custody. Military representatives did not immediately provide a statement to Insider.

A woman who identified herself as the girl's aunt, Casaundra Perez, posted a TikTok video that quickly went viral, alleging her niece was raped at the Camp Pendleton military barracks.

"They're trying to cover it up and place the majority of the blame on her. However, the reality is the whole facility allowed this to happen," Perez said in her video. "The security looked her in the face and allowed this man to bring a minor onto the base, where he proceeded to have sex with her. Due to her age, she could not have given this consent."

The sheriff's department told Insider in a statement that the girl ran away from her grandmother's Spring Valley home on June 9, and was ultimately reported missing on June 13. The statement said her grandmother waited several days before calling police because her granddaughter "had previously run away before, but always returned home quickly."

Authorities logged the 14-year-old girl's information into multiple missing persons databases and proceeded to investigate the girl's disappearance. On June 28, military police at Camp Pendleton located her and returned her to her grandmother, the statement said.
