The FBI says the two people who carried out the mosque attack in San Diego met online before the attack and later left writings that express hate, according to reporting. The outlets describe the writings as containing hateful rhetoric aimed at multiple groups, including Jewish people, Muslims, and the LGBTQ+ community, as well as Black people and women. The FBI also characterizes the materials as expressing hostility toward both the political left and right. The reporting indicates that investigators are treating the materials as part of the shooters’ broader ideology and intent. While the sources focus on the online connection and the content of the writings, they do not provide additional detail here about exactly when the online contact began, what specific platform was used, or whether the authorship of the writings has been independently corroborated beyond the FBI’s account. Overall, the information presented centers on the FBI’s description of pre-attack coordination and the discriminatory, extremist language contained in the materials left behind.
