OAKLAND — Steven Carrillo, the U.S. Air Force sergeant who allegedly murdered a Santa Cruz deputy earlier this month, has now been charged with a second deadly ambush of federal officers a week earlier — alongside a second man who allegedly drove the drive-by shooting van — in attacks that authorities say were driven by Carrillo’s extremist, anti-law enforcement views and ties to a group that believes the second American Civil War is coming soon.

During a Tuesday press conference, the Northern District U.S. Attorney’s office announced it was charging Carrillo with assassinating Federal Protective Services Officer Patrick David Underwood, who was shot and killed in Oakland on May 29. Federal prosecutors made the announcement at the Ronald V. Dellums Federal Building, just yards away from where Underwood and his partner — who was shot but survived — were fired upon from a white van, in what authorities have described as “an ambush.”
