(AP) — Federal authorities say a U.S. airman killed a federal security officer outside a federal courthouse in Northern California.
Air Force Staff Sgt. Steven Carrillo was charged with murder and attempted murder in the killing of federal officer Dave Patrick Underwood during a night of violent protest in Oakland on May 29. Underwood died from gunshot wounds and another federal officer was critically injured in the drive-by shooting outside the Ronald V. Dellums Federal Building.
Carrillo separately faces state charges in the fatal shooting and ambush of a Santa Cruz County sheriff’s deputy and the wounding of four other officers on June 6.
Carrillo is expected to enter a plea to the state charges on Wednesday.
