Investigators Examine Document Posted by San Diego Mosque Shooting Suspects

Law enforcement officials are working to authenticate a 75-page document posted online that appears to detail the motivations of two teenagers accused of killing three people at a San Diego mosque. The document contains sections apparently written by the two suspects, who are identified as an 18-year-old and a 17-year-old.

It includes anti-Islamic, antisemitic, and anti-LGBTQ material along with references to accelerationism, a white supremacist ideology.

The writings include Nazi iconography, extreme misogyny, and racist sentiments about Black people and other minority groups. The authors blame the Jewish community for what they describe as the problems of the modern world and list Brenton Tarrant, who carried out the 2019 Christchurch mosque shootings, as one of their heroes.

The document also contains views hostile to President Donald Trump, with the authors describing themselves as anti-MAGA.

The attack occurred Monday at the Islamic Center of San Diego in the Clairemont neighborhood. Officials said the suspects were believed to have died from self-inflicted gunshot wounds after the shooting. A security guard was fatally shot while protecting children and staff inside the mosque. Two other men were killed outside the building.

At a briefing Tuesday, the FBI confirmed that writings had been found online. Officials said they are dedicating resources to analyze the document to understand what led to the attack and how future attacks might be prevented. The suspects are described as having been radicalized online.

Officials said the victims were at the mosque to help build community during the first day of Dhul Hijjah, a sacred period in the Islamic calendar.
