TEQUESTA, Florida — The FBI analysis of blood from Austin Harrouff, the suspect in the cannibal-style attack and killings near Tequesta, Florida shows no evidence of him being under the influence of Flakka or bath salts at the time of the incident, according to a statement from his attorney.

The tests have been at the center of the investigation into the double murders.

Harrouff is accused of killing John Stevens and Michelle Mischon at their home inĀ August.

The first deputy on scene found Harrouff biting the face of Stevens.

Authorities also released extremely graphic crime scene photos. One shows Stevens in a pool of blood with several gashes on his body. Another shows a trail of blood in the driveway along with a beer bottle and sunglasses, blood spatters on plastic containers in the garage, and a pair of scissors.

Many of the photos are too graphic to show on television.

Other photos show a bloodied Harrouff in handcuffs.

Investigators asked the FBI to test the blood to see if Harrouff was on any drugs at the time of the attack.

Attorney Nellie King writes in the statement the findings “refute statements made early on in the investigation by Martin County Sheriff William Snyder, who suggested Austin Harrouff had ingested such drugs at the time of the attack on August 15, 2016.”

The toxicology tests did show evidence of ethanol, or alcohol, but did not identify a source of it.

“Harrouff may have ingested solvents or some other toxic solution when he was in the couple’s garage, liquids which could have contained alcohol and which shed light on Harrouff’s severe medical injuries, including damage to his esophagus and internal organs,” said King.

Documents showed Harrouff told deputies at the scene he ate “humans.”

The 19-year-old FSU student has been charged with two counts of first-degree murder and one count of attempted murder for attacking a neighbor who tried to intervene.

King said family members said Harrouff showed signs of a mental health disorder weeks before the incident. His mom called 911 in the hours before the attacks to say he claimed to have super powers.
