Appearing by video, with a tattoo resembling a pot plant on his forearm, Richard Clarke plead guilty Thursday to two counts of supplying contraband.

Clarke was sentenced to 12 months in prison and 24 months post-prison supervision to run concurrent with his current life sentence for the murder of Patrick Fitzhenry, a jury's verdict reached on Wednesday.

"So you fully understood what you were signing?" Deschutes County Circuit Judge Stephen Forte asked him Thursday.

"Yes," Clarke replied.

"Nobody's made any threats or promises to get you to sign this?" Forte asked.

"No," Clarke told him.

In May, while in the Deschutes County Jail awaiting his trial for murder, a corrections deputy noticed Clarke was acting suspicious. He quickly found out why.

"The corrections deputy opened the door to the cell, smelled marijuana, found ashes in the toilet, and a butane lighter," said Deputy DA Beth Bagley.

Clarke did not dispute what had happened, and when the judge asked him if he had anything to say for himself, he simply said: "Nothing at all."

Which is more than what he said Wednesday, when given the chance to address the family of Fitzhenry, his roommate, and the man he was just convicted of beating to death in October of 2010.

Clarke will spend the rest of his life in prison unless he's granted parole in 25 years. Fitzhenry's mother, Cheryl, told the courtroom Clarke only has one way out, and that's to ask for God's forgiveness.

"Then and only then is he going to be free from this hateful world he lives in," Fitzhenry said.

Clarke is still at the county jail for now. He'll be transferred to Coffee Creek Correctional Facility in Wilsonville in less than a week.
