Air Force sergeant charged in California shooting

An Air Force sergeant already jailed in the ambush killing of a California sheriff’s deputy was charged Tuesday with murdering a federal security officer outside the U.S. courthouse in Oakland the night of a sometimes violent protest last month.

In announcing murder and attempted murder charges, federal authorities alleged Staff Sgt. Steven Carrillo had ties to the right-wing anti-government “boogaloo" movement and that the plot to target law enforcement officers was hatched during an online chat among the group members.

Federal security officer David Patrick Underwood, 53, was killed the night of May 29 and his partner was wounded as they guarded the Ronald V. Dellums Federal Building in Oakland while a large and raucous demonstration over the police killing of George Floyd was under way nearby.

Carrillo and an accomplice parked a white van near the courthouse and Carrillo fired an AR-15-style rifle at the guard station where Underwood and his partner were located. Officials said Carrillo used the protest as cover for the crime and for his escape.

Carrillo's attorney, Jeffrey Strotter, did not immediately respond to a telephone message seeking comment.

Officials also charged the alleged getaway driver, Robert Alvin Justus, Jr., with aiding and abetting the murder and attempted murder. Justus turned himself into the FBI on Thursday while they had him under surveillance.

Carrillo separately faces state charges in the June 6 fatal shooting of Santa Cruz County sheriff’s Sgt. Damon Gutzwiller and the wounding of four other officers in Ben Lomond, an unincorporated community outside the beachfront city of Santa Cruz south of San Francisco. Authorities have said that Carrillo, a leader in an elite military security force, ambushed the officers.

Carrillo is being held without bail in jail in Monterey County. He is expected to enter a plea to the state charges next month.

Federal authorities said Carrillo is part of the “boogaloo” movement, whose anti-government adherents derived the term from the panned 1984 movie “Breakin’ 2: Electric Boogaloo” and use it as a code word for a second U.S. civil war.

Another derivation of “boogaloo” is “big luau” and Hawaiian garb is common among members' clothing. Officials found a American flag-like patch on Carrillo's bulletproof vest that depicted an igloo and a Hawaiian-style print, themes commonly associated with the movement.

Carrillo also wrote, using his blood, phrases associated with the movement onto a vehicle he had carjacked before he was taken into custody following the killing of the Santa Cruz deputy. The gun used in Underwood's slaying also was used in that attack.

Authorities do not believe the Oakland attackers coordinated to make attack plans with three Nevada men who had plotted to spark violence during recent protests in Las Vegas and also identify with the “boogaloo” movement.
