FBI: No hallucinogens found in system of face-biting suspect

(AP) — The Florida college student accused of randomly killing a couple and chewing on the dead man's face had no detectable hallucinogenic drugs in his system, according an FBI toxicology report released Wednesday.

Deputies had said when they arrived at the couple's home, they found the then-muscular former high school football player and wrestler in his underwear, making animal noises and biting Stevens' face as he pinned the man's body to the driveway.

According to court documents, one deputy ordered Harrouff off Stevens at gunpoint while another used an electric stun gun on him but he wouldn't let go.

[...] a deputy with a dog arrived and its bites enabled deputies to subdue Harrouff.

Harrouff, who had no previous arrest record, told deputies, "Help me, I ate something bad" and then admitted it was "humans" as he spit out a piece of flesh, court documents show.

According to police reports released Wednesday, Harrouff's family and friends told detectives he had been acting strangely in the days and hours before the attack.

Harrouff's parents issued a statement days afterward expressing condolences to the Stevens family and apologies to neighbor Jeff Fisher, who was stabbed while trying to rescue the couple.
