The gunmen involved in the tragic attack at the Islamic Center of San Diego left behind a disturbing manifesto filled with hateful ideology. Reports indicate that both suspects, 17-year-old Cain Clark and 19-year-old Caleb Vasquez, may have crafted this 75-page document before their fatal actions.
This manifesto conveys an alarming vision of chaos, advocating for a race war and societal breakdown. It intertwines a variety of extreme ideologies, encompassing anti-Trump, anti-liberal, and other prejudiced sentiments, rooted in deep-seated grievances and nihilism.
Law enforcement believes they possess a genuine copy of this manifesto, which features symbols linked to Nazi ideology, such as the Black Sun and references to the violent group Atomwaffen. Online profiles associated with Clark further display Nazi motifs, including imagery of Hitler.
One disturbing assertion, attributed to Clark, reveals a dismissal of both left and right ideologies, showcasing contempt for all sides. Additionally, the authors draw inspiration from notorious figures like Ted Kaczynski and Timothy McVeigh.
Reports indicate that the manifesto venerates Brenton Tarrant, the 2019 Christchurch mosque shooter. The authors reportedly dubbed their document after him, labeling him “Saint Terrant” and considering his livestreamed attack a model to follow.
Witnesses describe a shocking normalcy preceding the attack. Jennifer Du, a neighbor, recounted seeing Clark just a day prior, while another resident expressed disbelief at the family’s connection to such a horrific act.

The shooters were not “right or left” politically.
They were Nazi Bolsheviks who blamed “capitalism” and “Trump” for our “joke” of a “democracy” and wanted to burn down the system. pic.twitter.com/7IIQR92VYq
