A former boxer who competed in the 2008 Olympics was arrested Wednesday for allegedly threatening a mass shooting at a Florida gym, the Miami Herald reports. According to the New York Daily News, 39-year-old Azea Augustama was working as a personal trainer at BOXR Gym in Miami when he was kicked out earlier this month after an alleged argument. Police say Augustama called them on Tuesday in an attempt to get his belongings from the gym after being issued a trespass warning, then posted an Instagram photo of Parkland shooter Nikolas Cruz. He allegedly wrote that he was "considering shooting" people for being kicked out of his gym and "saying I touched a girl," and that he was "willing to shoot with an actual gun or [bazooka]." Police say he then drove to a local pawn shop to put a deposit on an AK-47 rifle. Augustama was detained at the pawn shop before he could take possession of the gun. He was charged with two felony counts of issuing written threats to commit a mass shooting and one felony count of threatening to kill. Augustama, who was born in Haiti and moved to Florida when he was a child, finished his boxing career with a 20-3-0 overall record and 12 knockouts. He last fought in 2017.
