A cannibalistic double-murderer from Florida could end up walking the streets again — without ever going to trial. Former Florida State University fraternity member Austin Harrouff, 25, was deemed not guilty by reason of insanity Monday after randomly hacking John Stevens and his wife Michelle Mischon to death with a machete in 2016. Deputies said they found Harrouff kneeling over Stevens and gnawing on his face, noting that he spit out pieces of flesh before being taken into custody.
