[Ed. – AP report here. The federal officer was Pat Underwood. Carrillo, an Air Force sergeant stationed at Travis, is a Raven. Sickening. Something else going on there, obviously. He was carrying around homemade pipe bombs. Deputy Gutzwiller, who was 38, leaves behind a pregnant wife and 2-year-old son.]
The U.S. Air Force sergeant suspected of killing a Santa Cruz County deputy is now believed to have had a hand in the killing of a federal officer in Oakland.
Steven Carrillo was arrested on Saturday after authorities say he opened fire and deputies in Ben Lomond, killing Sergeant Damon Gutzwiller.
As Dan Noyes and the ABC7 News I-Team have been reporting, the FBI was investigating whether Carrillo had been involved in a shooting that killed a security officer at the Oakland Federal Building last month.
