KPBS News San Diego reports that battalion sergeant major at the Marine Corps' San Diego boot camp was arrested last week after his spouse reported months of abuse, according to a restraining order filed Tuesday.

Sgt. Maj. Gerardo Trevino was arrested by Naval Criminal Investigative Service (NCIS) agents Sept. 11, the Marines said in a statement. NCIS confirmed Trevino remains confined in the brig.

But neither would say why Trevino was arrested, both citing the ongoing NCIS investigation.

Stars and Stripes reports that Trevino was arrested days after his wife alleged he hit and punched her during an argument, according to a statement filed in a San Diego court.

In a domestic violence restraining order filed Tuesday in San Diego Superior Court, Trevino's wife alleges that the sergeant major had been controlling and abusive for months, hitting, punching, and, in one incident last month, strangling her until she 'passed out.'

Trevino, originally from Texas, enlisted in the Marine Corps in 2004 and conducted deployments to Iraq and Afghanistan. He assumed his position at Marine Corps Recruit Depot San Diego in June 2023, according to his official Marine Corps biography, which has since been removed.

Trevino has been placed in pretrial confinement, said Darwin Lam, a spokesman for NCIS, who also confirmed that agency is conducting “a thorough investigation” into Trevino per Task and Purpose.

His military awards include the Meritorious Service Medal, Navy Commendation Medal in lieu of second award, Navy and Marine Corps Achievement Medal in lieu of fourth award, and the Military Outstanding Volunteer Service Medal.

He is among several senior enlisted leaders who have been fired recently, including Army Sgt. Maj. Jaime I. Rubio; Command Sgt. Maj. Harold “Ed” Jarrell; Command Sgt. Major Veronica E. Knapp; and Command Sgt. Maj. Matthew Carlson.
