Nazism-fueled gunman: prior restraining order foreshadowed San Diego mosque attack
Caleb Vazquez, 18, and an accomplice killed three men at the San Diego Islamic Center in a hate-fueled attack tied to online white-nationalist extremism; 15 months earlier Chula Vista police sought a gun-violence restraining order against Vazquez’s father after concerns he idolized Nazis and mass shooters, with firearms moved out of the home to storage; Vazquez had been in mental-health treatment and had 5150 holds, and investigators say the attackers were radicalized online and left extremist writings; the attackers died by self-inflicted wounds, and a security guard helped save others.
