San Diego mosque shooting horror takes an even darker turn after police revealed the teen shooters were allegedly radicalized online and wore Nazi symbols during the deadly attack. Authorities say racist messages, swastikas, Atomwaffen-linked imagery and the chilling phrase “Race War Now” were found on weapons and gear connected to the suspects. The FBI is now investigating the livestreamed mosque attack that killed three people, including security guard Amin Abdullah, hailed as a hero for saving lives during the massacre.
