Two teenagers behind the killing of three people in an attack at a mosque in San Diego met online and bonded over a "broad hatred" of different religions and racial groups, U.S. authorities said Tuesday as details emerged about the deadly assault.
Mark Remily of the FBI said during a news conference that authorities have uncovered writings by the suspects. Authorities declined to specify what ideologies or views were expressed by the shooters.
Authorities have also recovered 30 firearms and a crossbow from two residences searched in connection with the investigation.
Remily said authorities are still trying to uncover whether the shooters had broader plans.
Hours before Monday's attack, police were racing to find the two teenagers who would ultimately be deemed responsible.
