A U.S. Air Force sergeant accused of ambushing Santa Cruz County deputies is also believed to be the gunman who shot a federal officer in Oakland, a law enforcement source confirmed Thursday, linking the extraordinary tragedies that may have been spurred in part by extremist, anti-law enforcement views found in the dark corners of social media.

The explosive claim connecting the cases comes the same day that Steven Carrillo, 32, was charged with 19 felonies, including murder, attempted murder, explosives charges and carjacking after the deadly rampage Saturday afternoon that terrorized the mountain community of Ben Lomond, where Carrillo grew up and lived with his father.
