Hilton, 61, is scheduled to appear before Superior Court Judge Bonnie Chessher Oliver at 1 p.m. today. Law enforcement officials have said they were told Hilton would plead guilty in exchange for a life sentence.
The guilty plea, if entered, would come less than a month after Hilton was arrested and charged in the death of 24-year-old hiker Meredith Emerson, who was abducted from the Byron Herbert Reece Memorial Trailhead on Jan. 1. Authorities believe she was killed by blunt force trauma to the head on Jan. 4 in the Dawson Forest Wildlife Management Area.
Hilton led authorities to her decapitated body on Jan. 7, after prosecutors from Union County and the U.S. Attorney's office agreed not to seek the death penalty against him.
Hilton remains a suspect in murders in North Carolina and Florida but has not been charged in either case.
