It wasn't bath salts

The naked Florida man who chewed off the face of a homeless man was not high on bath salts after all. At least that's what theMiami-Dade CountyMedical Examiner Department is saying.

Investigators say the only thing they found in 31-year-old Rudy Eugene's system was marijuana---nothing else!

So now the question is what could have driven a seemingly normal guy to eat another man's face off?!
