At 1AM on a November night in 2016, a family in Loxahatchee, Florida awoke to a real-life nightmare. It was a horrific scene; screams to call 911, a young man dying in his bedroom. From the house emerged three survivors: a distraught mother, her boyfriend and the best friend. But it was a fourth person, they claimed, who had made their way inside the locked house in the middle of the night, committed the murder, and escaped.
