A California surfing school owner was charged Wednesday with killing his two young children with a spear gun in Mexico because he believed they would become monsters, authorities said. Matthew Taylor Coleman, 40, of Santa Barbara is facing a federal charge of the foreign murder of U.S. nationals, the U.S. attorney’s office said in a statement. Coleman was detained at the border checkpoint, where during an interview with an FBI agent “he explained that he was enlightened by QAnon and Illuminati conspiracy theories and was receiving visions and signs revealing that his wife, A.C., possessed serpent DNA and had passed it on to his children,” according to the affidavit.
