Peterson loses single-cell privilege

Peterson told WRAL News that he had too many stamps and too much peanut butter and orange juice in his cell and was in violation of prison rules.

Those infractions earned him a move to the prison's dormitory housing.

Peterson was convicted in 2003 of murdering of his wife, Kathleen. She was found dead in a pool of blood at the bottom of a staircase in the couple's home on Dec. 9, 2001.

He has maintained she died in an accidental fall.
