2020 boogaloo murders

In late May and early June 2020, two ambush-style attacks occurred against security personnel and law enforcement officers in California. The attacks left two dead and injured three others.

The attacks began on May 29, when a drive-by shooting occurred in front of a federal courthouse in Oakland, resulting in the death of a security officer contracted with the Federal Protective Service. Over a week later on June 6, Santa Cruz County sheriff's deputies were shot at and also attacked with improvised explosive devices; one of them died as a result.

U.S. Air Force sergeant Steven Carrillo was arrested soon after the second attack. A second suspect, Robert Justus, surrendered to authorities five days later. The FBI indicated that Carrillo was associated with the boogaloo movement, a loosely organized American far-right anti-government extremist movement whose participants say they are preparing for a second American Civil War. Carrillo used the George Floyd protests as a cover to attack police officers, according to the FBI. A white van owned by Carrillo contained a ballistic vest with a patch bearing boogaloo symbolism. Carrillo is alleged to have written "boog" and the phrase "I became unreasonable" (a popular meme among boogaloo groups) in his own blood on the hood of a vehicle he hijacked. According to federal authorities, the suspects were motivated by the boogaloo movement's ideology, and allegedly intended to spread its extremist views and start a civil war.
