Austin Harrouff, a 19-year-old FSU student, is accused of murdering married couple John Stevens and Michelle Mishcon as they sat in the garage of their Tequesta, Florida home. The 19-year-old was dubbed the “cannibal killer” by the media after he allegedly stabbed the couple to death, biting one of his alleged victim’s face and abdomen while making animal noises, and then stabbing the couple’s neighbor who was attempting to save their lives.WATCH: Father Of Frat Boy Dubbed 'The Cannibal Killer' Describes What He Calls Son’s ‘Abnormal’ Behavior Before The Attack
