Online Radicalization Ties Teens to San Diego Mosque Attack, FBI Says

Investigators say two teens, Cain Lee Clark (17) and Caleb Liam Vazquez (18), were radicalized online before killing three people at the Islamic Center of San Diego and then taking their own lives; a manifesto and writings found in their belongings indicate broad religious and racial animus. About 30 guns and a crossbow were recovered from the suspects’ homes, and a security guard who confronted them and two mosque members were killed; authorities are investigating the incident as a hate crime. The victims—Mansour Kaziha, 78; Nader Awad, 57; and Amin Abdullah—were praised for their actions, and a vigil is planned as the community processes the tragedy.
