OAKLAND — Four people have been indicted on conspiracy charges related to the May 31 burglary of a gun store in Hayward, in which prosecutors say nearly 30 guns were stolen, according to court records unsealed Monday.

The indictment names as defendants Dashawn Taylor, Anthony Craft Jr., Tyronza Hampton Jr., and a fourth person whose name is still sealed because he or she has not been arrested. Prosecutors allege the four conspired to steal 27 guns from Richardson Tactical.

The four were identified in part thanks to surveillance footage from store, though prosecutors say nine people participated in the burglary. Authorities matched one defendant’s tattoos to those seen on one of the burglars’, and screen-shotted Instagram pictures of another defendant posing with two guns that appear to be the same type as two of the stolen weapons.

In a written statement, Northern District U.S. Attorney David Anderson — whose office filed the charges — suggested the nine burglars took advantage of protests elsewhere in the Bay Area in response to the killing of George Floyd by Minnesota police officers.

“This burglary occurred on a night when Hayward and many other cities in the Bay Area and across the country were experiencing civil unrest and protests,” Anderson said. “My office stands in support of all Americans exercising their First Amendment rights to peaceable assembly and speech.  But we will also investigate and seek justice for those who use the cover of lawful protests to break the law.”

Taylor was arrested a week after the burglary, after a vehicle he was a passenger in crashed while, “fleeing the scene of a shooting” in Oakland. Police found a gun on him that had been stolen from Richardson Tactical, the criminal complaint alleges. Authorities later reportedly identified him as a burglar who’d pulled his mask down in front of a surveillance camera.

The evidence against Craft includes Instagram pictures of him pointing two pistols at a camera, which federal authorities screen-shotted off of his Instagram account, the complaint alleges. The guns were identified as the same types of pistols stolen from Richardson Tactical, including one — a P365 SAS model — which authorities wrote is new to the market and not yet in wide circulation.

Hampton, meanwhile, was identified by his hand tattoos, which authorities allege match tattoos of one of the burglars. He was also identified as the owner of a gold Buick sedan that was captured on surveillance footage driving up to the burglary and leaving afterwards.
