The San Diego mosque shooters were “radicalized online,” cops say — as it’s revealed they wore Nazi symbols and etched racist statements on their gear as they opened fire outside an Islamic Center, killing three people in the process.

The two teens “did not discriminate on who they hated,” law enforcement officials said in a press conference Tuesday, adding they had recovered over 30 guns and a crossbow in connection to the suspects.

A livestream video of the horrific attack, currently being probed by the FBI, shows Cain Clark with a Black Sun symbol, which is associated with Nazi Germany, square on his chest. Nazi SS commander Heinrich Himmler had the symbol inlaid into the floor of the Wewelsburg castle.

Another symbol associated with a small online neo-Nazi group, the Atomwaffen Division, can also be seen on one of the shooters’ shoulders. Atomwaffen is the German phrase for “atomic weapons.”

It’s unclear if the two teenagers claimed membership to the group.

Also seen on the handgun of one of the shooters is the statement, “race war now,” right above a swastika. Neo-nazis and white nationalists are known for promoting race wars to overthrow the government or create a white ethnostate.

The teen killers gunned down three people at the Islamic Center of San Diego on Monday. Among the dead included security guard and father of eight Amin Abdullah, who police say prevented more deaths, as well as a grocery store owner and another man.

Once back inside their vehicle, the livestream video showed Clark shoot his companion twice in the head before turning the gun on himself.

Anti-Islamic writings were also found in the suspects’ vehicle, according to a law enforcement source.

A shotgun and a gas can with an “SS” sticker on the side, which appears to represent the Schutzstaffel paramilitary group from Nazi Germany, were located at the scene where the gunmen’s bodies were discovered.

Clark and Vasquez were found dead inside a BMW from self-inflicted gunshot wounds, only a few blocks from the Islamic Center of San Diego.

The shooters’ motivations are unknown, though it appears to be a crime aimed at the Muslim faith.
