BOISE -- An Idaho inmate accused in the 1983 rape and murder of an Ogden girl has been cleared for extradition by a judge.
The Idaho Department of Correction will send a letter today letting Utah authorities know they can begin making plans to pick up Gregory Seamons.
Seamons, 45, was charged in Utah a year ago with rape and first-degree murder in the slaying of 11-year-old Rebecca Lemberger.
Utah investigators say DNA evidence from the scene of the murder matched Seamons' DNA from a national database.
In a 2012 letter, Seamons acknowledged "fooling around" with the girl before her death, but he suspects his father Larry Bingham Seamons likely killed her. Larry Seamons died a decade ago.
Seamons wrote that his father picked him and a neighborhood girl up one morning, and his father said he would drive him to school first and then drop her off at another school.
"I never saw this girl again and a few days later it came out on the news that she had been killed," he wrote in the letter.
The head of the Utah State Crime Lab says it would be almost impossible for a father's DNA to be confused with that of his son.
Jay Henry has said, "Only one other person can have the exact same DNA as you, and that's a twin."
"I can't imagine that happening," he said of the possibility of a father's DNA being mistaken for the son's. "The word mix-up is not even applicable. It doesn't make sense."
Lemberger, who lived in the same neighborhood, was last seen walking to school March 2, 1983. Her body was found the next day in a shed in a field. She had been sexually assaulted, and she died from a blow to the head.
Seamons is serving a sentence of four to 11 years for an unrelated 2007 second-degree kidnapping conviction in Ada County, Idaho. He was scheduled to be released in 2017.
He is expected to arrive in Utah in a month.
