An Air Force sergeant has been arrested and is facing murder charges for the death of one police officer and the wounding of two in an ambush that involved several Improvised Explosive Devices (IED), last Saturday in California.

Sergeant Damon Gutzwiller, a deputy with the Santa Cruz County Sheriff’s Office, was killed during the incident. Another deputy and a California Highway Patrol officer were injured.

They were responding to a call about a suspicious van that contained weapons and bomb-making material. They located the vehicle and began following it. When it stopped in a residential area, the police officers dismounted and began investigating. At that moment, they were ambushed.

Sergeant Steven Carrillo, an Airman assigned to the 60th Security Forces Squadron out of Travis Air Force Base, has been arrested. He was also wounded during the exchange of fire following up to his arrest.
