Online viewers watched the San Diego mosque attack as it happened, recordings show

CBS News analysis shows multiple viewers watched the San Diego Islamic Center attack live via a Signal livestream, with a Discord user recording and sharing the feed; one viewer urged others to alert police, though it’s unclear if anyone did. The two teen gunmen died by suicide after killing a third victim, and some watchers appeared to be overseas. Discord preserved related data for investigators, while authorities and experts note how online platforms enable such violence.
