An active-duty airman stationed at Travis Air Force Base, California, will be charged with first-degree murder for allegedly killing a sheriff’s deputy and wounding two other law enforcement officers, according to the Associated Press.

Staff Sgt. Steven Carrillo assigned to the 60th Security Forces Squadron, according to the Air Force. Carrillo arrived at Travis Air Force Base on June 28, 2018.

Carrillo is accused of ambushing deputies that had been pursuing a van that pulled into a driveway at his home on Saturday, the Associated Press reported. The deputies were attacked by gunfire and explosive devices after getting out of their vehicles.

Sgt. Damon Gutzwiller, of the Santa Cruz County Sheriff’s Office, was fatally wounded in the exchange of fire. Another deputy was wounded by either the gunfire or shrapnel and then hit by a vehicle as Carrillo tried to get away.

Carrillo was arrested after allegedly trying to carjack a vehicle. He was shot while being arrested and treated for non-life-threatening injuries.

The Associated Press is reporting that Carrillo’s wife, who was also in the Air Force, was found dead in a South Carolina hotel in May 2018. Local officials and the Air Force Office of Special Investigation concluded she died by suicide.
