These shocking crime scene photos show the 'cannibal' frat boy moments after he allegedly attacked a couple at random and chewed the dead man's face - but a toxicology report has revealed he had no hallucinogenic drugs in his system at the time.
Austin Harrouff is accused of beating and stabbing John Stevens, 59, and his 53-year-old wife Michelle Mishcon outside their home in Jupiter, Florida, on August 15.
The dramatic images – showing the 19-year-old covered in blood, handcuffed on the ground and with his mouth hanging open – were released by state prosecutors along with court documents which went into detail about what happened on the night.
It comes as an FBI toxicology report released on Wednesday revealed that Harrouff had no hallucinogenic drugs in his system at the time of the attacks – only a trace amount of marijuana.
Martin County Sheriff William Snyder had previously speculated that Harrouff may have been on flakka or bath salts.
The synthetic drugs have been linked to causing paranoia, nightmarish visions and periods of super-human strength - but they weren't detected in the Florida State University student.
