I agree with you both...I'm from Miami and crazy **** happens here on a daily basis, but this was pretty wild.
I'm not sure where people come up with the "zombie" stuff, though. It is mostly described as a type of cannibalism. As my husband said, the dude was so whacked out of his mind that he probably thought the other guy's face was a chocolate sundae or something.
I wonder if it could have been LSD. I've heard that it can raise your body temp to the point where you feel like you're on fire (think hot flashes multiplied). That could explain why he took his clothes off.
But yeah, drugs are bad. Somebody mentioned bath salts...the situation with bath salts is out of control in states like Maine.
