The two young men who killed three people at a San Diego mosque on Monday published a conspiracy theory-filled manifesto whose primary focus was on Jews, calling them the “universal enemy.”
The manifesto’s contents also suggest they may have had additional plans to target Jewish institutions.
Authorities have identified Cain Lee Clark, 17, and Caleb Liam Vazquez, 18, as the shooters who killed a security guard and two members of the Islamic Center of San Diego. The two livestreamed the attack before both were found dead in a car by apparent suicide, blocks away from the mosque.
The three killed at the mosque were Amin Abdullah, 51, Mansour Kaziha, 78, and Nadir Awad, 57.
Jewish leaders across the country and in San Diego widely condemned the attack.
The 74-page manifesto, which contains a section written by each shooter, reveals a wide-ranging hatred rooted in white Christian nationalist ideas, including Great Replacement Theory, and fueled by the two teenagers’ own social alienation. Among the other groups attacked in the document are Muslims, women, Black people, gay and transgender people, and immigrants.
But the shooters’ deepest resentment seemed reserved for Jewish people.
‘The universal enemy’
The manifesto listed previous antisemitic shootings at the Tree of Life synagogue and Chabad of Poway among the teens’ many sources of inspiration, calling the assailant in the latter incident a “saint.” It called the Jews “the children of Satan.” It denied the Holocaust as a “complete fabrication.” Vazquez called Adolf Hitler his hero; in his section, Clark wrote out the Fourteen Words, a neo-Nazi declaration.
“Everyone has their own idea of who is to blame for all the wrong in the world,” Vazquez wrote in a section titled “The Universal Enemy.”
He printed his answer to the question four times in a row in all capital letters: “It’s the Jews.”
Authorities have said the shooters met online before realizing they both lived in the San Diego area, without specifying the platform where they met.
But the document’s cover pages also provided a clue to their radicalization, bearing the insignia of Atomwaffen Division, a neo-Nazi group that emerged during the first Trump administration.
Atomwaffen members are part of a network of mostly online extremist groups that subscribe to “accelerationism,” the idea that forcing societal collapse through an all-out race war is the only way to restore white supremacy and save civilization. The idea is propounded by a white nationalist named James Mason, author of a book called Siege that both shooters cited.
“Though officially I was not a part of any groups or organizations there are many I support, I would even go so far as to say I did it for Atomwaffen Division, Terrorgram, The Base, and North Korea,” Vazquez wrote.
Atomwaffen members have been convicted in previous antisemitic murders. In 2019, one named Samuel Woodward lured a gay and Jewish college student named Blaze Bernstein to an Orange County park before stabbing him to death. Woodward, who was 20 at the time, is now serving a life sentence, and Atomwaffen fractured into other groups in the years after his arrest.
Secondary targets
Whereas the shooters were unsparing toward Jews in the manifesto, with Vazquez calling them the “most evil creature in the world,” they espoused mixed feelings about Muslims in the document before they killed three. “I don’t hate Muslims, at least not really,” Vazquez wrote. “What I hate is the religion of Islam itself and them invading my country.”
He added that Islam “is completely contradictory to both Western morals and values and Christianity.”
But he wrote only three paragraphs about Islam and Muslims — about one page — before the section ends with the word “unfinished” in brackets.
Clark appeared more committed to the eradication of Islam in his writing. Muslims and Jews, he said, “must be isolated and exterminated.” Yet he, like Vazquez, wrote several pages denigrating Jewish people.
The shooters did not state why they ultimately targeted a mosque. Vazquez wrote their plan was to “cause as much death and destruction” as fast as possible with a “diverse” selection of targets. The document provides lines for listing three separate locations, but none of them are filled out.
“All locations were surveyed and mapped out to the best of our ability,” he wrote.
