CRESCENT CITY, Calif. — A Northern California mixed-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 and mayhem charges.

Jarrod Wyatt of Crescent City agreed to a plea deal in which he will serve 50 years to life in prison, Del Norte County prosecutors said. His official sentencing is scheduled for Oct. 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. “We saved Taylor’s family the agony from reliving the incident at the trial.”

Wyatt’s attorney, James Fallman, said his 29-year-old client didn’t want to testify at trial and he didn’t want his family to testify.

“We looked for an agreement that would at least give him the opportunity to be paroled someday,” Fallman said. “As bad as 50 years to life sounds, it’s better than life without the possibility of parole.”
