Nikolas Cruz, the troubled 19-year-old who has been charged with the premeditated murder of 17 people at his former high school in Parkland, Florida, told authorities that “demons” gave him instructions on how to commit one of the deadliest mass shootings in U.S. history. Investigators told ABC News that Cruz said he heard voices in his head described as demons as he gunned down his victims Wednesday at Marjory Stoneman Douglas High School which he had attended from Jan. 13, 2016, to Feb. 8, 2017.

In arrest records published by The New York Times, Cruz admitted to being the school shooter and said he entered the school campus armed with an AR-15 “and began shooting students that he saw in the hallways and on the school grounds.” He said he also brought additional loaded magazines to the school which he kept hidden in a backpack until he began his attack. When the students started running after he began his attack, Cruz discarded the AR-15 and a vest with additional magazines to blend in with the crowd and eluded police until he was arrested without incident in the nearby Coral Springs neighborhood.
