Bath Salt...this drug has had several incidents before. This particular guy was arrested previously in Miami, for attacking his mother.
It took 3 tasers to get his ass down, he wasn't on drugs then.
But these particular drugs heat up your body temperature. Apparently it feels like your insides are melting. That's why he took of his clothe. The growling is also a symptom of these drugs.
You don't feel pain.
One dude was walking naked on the street when he got hit by a cab, according to the police report. He gave the cops a hell of struggle who trying to help him severely injuring one of the cop's hand. That dude survived.
But this story freaked me out. Think about it, a naked dude pins your ass down and chews your face off, eyeballs, nose down to your chin. No fucking zombie, a human did that, a human who probably wouldn't have done that if he wasn't on some drug.
I prefer Machete.
