The FBI says two reclusive teens accused in a San Diego mosque shooting met online and bonded over an extreme, conspiratorial worldview. At a news conference, the agency said investigators are combing a manifesto connected to the suspects and examining its contents as part of an ongoing effort to understand their motivations. According to the FBI’s remarks, the materials include white supremacist rhetoric and alleged references to Nazi ideology. Authorities also continue investigative and law-enforcement actions at properties connected to the suspects, including raids by police. The FBI’s statements frame the case around online contact between the two individuals and the ideological themes described in the manifesto being reviewed. Details about how and when the individuals became radicalized, the full extent of their plans, and the specific contents of the manifesto have not been fully laid out in the provided reports. The investigation continues as agencies assess evidence, pursue additional leads, and work to establish an accurate timeline of events.
