Sean Michael Albert, 19, waived his preliminary hearing and is now in detention, according to court filings.Using a slur for LGBTQ people, he said 100 people "will die, Cya there!""After providing three possibilities of why the FBI would want to speak with him (none of which involved illegal activity), Albert responded that it was probably because '[he] made a post online that may be perceived as a mass shooting threat,'" the criminal complaint against Albert read.According to FBI interviews with Albert's apartment manager, the security manager at Full Sail University and Albert's roommate, Albert had "a history of violence and a pattern of concerning behavior.""In particular, it is assessed that Albert has rapidly progressed from making controversial statements online, to confrontation with classmates and peers in online spaces, as well as direct confrontation with people outside of his university," the complaint read."
