Authorities provide an update on the fatal shooting at an Islamic center in San Diego. The attack occurred on Monday and results in three deaths. According to the FBI, investigators say the two teenage attackers were radicalized online and did not limit their targets based on whom they hated, indicating the motive was not confined to a single group. Multiple sources report that the 17- and 18-year-old assailants first met online, where they exchanged and adopted white supremacist views. Investigators also point to writings attributed to the attackers as part of the radicalization picture. The attackers carry out the shooting at the mosque before taking their own lives shortly afterward. The outlets describe the development of details as the investigation continues, including how the online interactions contributed to the attackers’ beliefs and connection to the violence. The FBI’s account is based on the ongoing review of information collected in the case.
