Maybe it was bath-salts from Silk Road, those cause the brain to cook a little. I remember the bath-salt zombie media blitz of 2013 where one woman dropped dead from a cooked brain however, she killed a pitbull by biting to death first. Also this one dude in Florida ate pieces of another guys face after he failed to score. Classic Satanic drug-induced homo-necrotic and necro-bestiality activity.
