A MARTIAL artist accused of ripping out his friend’s heart and removing his tongue while the two were on hallucinogenic drugs has pleaded guilty to murder.

Jarrod Wyatt agreed to a plea deal, in which he will serve 50 years to life in prison, prosecutors said.

His official sentencing is scheduled for October 4.

Wyatt pleaded guilty to first-degree murder involving mayhem in the March 21, 2010, death of his sparring partner, 21-year-old Taylor Powell, prosecutors said.

“The earliest he’ll be able to see a parole board is 2062,” District Attorney Jon Alexander said.

When police arrived that day at a home at the mouth of the Klamath River, they found Wyatt naked and covered in blood.

He told the officers, “I killed him,” and said he had cut out Mr Powell’s heart and tongue, according to court documents.

The officers found Mr Powell’s body on the couch of the Requa home.

His chest was cut open, and his heart, tongue and the skin of his face were gone, court records said.

His heart was found charred in a wood-burning stove.

An autopsy determined the organs had been removed while Mr Powell was still alive, the documents said.

Witnesses say the two had ingested hallucinogenic mushrooms before the attack and believed they were involved in a struggle between God and the devil.

Wyatt had entered pleas of not guilty and not guilty by reason of insanity, prompting psychiatrists to evaluate his mental competence.

In May, a judge ruled Wyatt was competent to stand trial.
