Photos from the scene of a deadly shooting at a San Diego mosque

Federal authorities say the teenagers who killed three people at a San Diego mosque met online and shared a “broad hatred” toward different religions and races. Mark Remily of the FBI said Tuesday that authorities have uncovered writings by the suspects. Authorities have also recovered 30 firearms and a crossbow from two residences searched in connection to the investigation. Remily said authorities are still trying to uncover whether the shooters had broader plans.
