Now prosecutors have released startling images which show the 19-year-old student being handcuffed and taken away by police and with his mouth agape.

In one particularly chilling picture, it looks like he has something stuck on his teeth.

There are also photos of a bloody knife and pair of scissors and images showing splatters inside the house.

Another picture was taken in the garage where Mishcon's body was found, reports the Mail Online.

The grisly images were released after court documents revealed Harrouff spat a chunk of flesh out of his mouth when speaking to officers.

He then admitted it was 'human'.

Harrouff reportedly told deputies, "Help me, I ate something bad" admitting it was "humans".

It was then he spat out the piece of flesh, court documents show.

He then pleaded with officers to kill him, saying: "shoot me now, I deserve to die."

Police have told how when they arrived at the tragic couple's home, they found the accused sitting in his underwear making animal noises and biting John Stevens' face.

Despite using an electric stun gun on him the muscly student wouldn't let go of Mr Stevens.

It was only when he was bitten by a police dog that he could be overpowered.

Ms Mishcon's body was then found.

According to police reports, the former college footballer had been acting strangely in the run up to the attack.

His mother told police he claimed to have superpowers and thought there were demons in the house.

Harrouff's father, Wade Harrouff, told investigators they had gone for a walk the afternoon before the killings and came across two turtle shells. He said his son pulled out a knife and said something was going to happen.

He said he convinced his son to put away the knife, which was later found near the victims.

After a bizarre family meal at a nearby sports bar, where Harrouff tried to eat cooking oil, he walked the four miles to the couple's home.

The crime reports details a brutal attack, with blood found all over the couple's driveway and their bodies displaying major wounds.

Both were pronounced dead at the scene.

The court was also told on Wednesday the Florida college student had no detectable hallucinogenic drugs in his system, according an FBI toxicology report.

Nellie King, Harrouff's attorney, said Wednesday that her client is mentally ill.

Harrouff has pleaded not guilty to first-degree murder and other charges. He could face the death penalty if convicted.

Prosecutors declined comment.
