OGDEN -- Weber County Attorney Dee Smith said it is up to Idaho authorities when an inmate will be extradited for the 1983 sexual assault and beating death of an 11-year-old Ogden girl.
An arrest warrant for first-degree aggravated murder and rape was issued Friday in Ogden's 2nd District Court for Gregory L. Seamons, 44, in the slaying of Rebecca Lemberger.
Lemberger was last seen walking to school on March 2, 1983, but she never arrived. Her body was found the next day in a shed in a field. She had been sexually assaulted and died from a blow to the head.
DNA evidence taken from the scene of the murder matched with Seamons' DNA from a national database last year, Smith said.
Seamons is currently serving a sentence of four to 11 years for a 2007 second-degree kidnapping conviction in Ada County, Idaho. He is scheduled to be released in 2017.
"We had to reopen the case, track down witnesses, talk to family members and neighbors," Smith said Monday. "Investigators talked with multiple witnesses in three different states. We tied all of the pieces together."
Seamons could challenge extradition by demanding a court hearing. No Utah court date has been set yet, but Smith said he hopes "it moves forward in the near future, pretty quickly."
He added, "Idaho is aware of the charge. He's their prisoner, so they're going to have to decide when they plan to release him."
Police also plan to investigate whether Seamons could be a suspect in other local unsolved crimes, according to Ogden Police Lt. Scott Conley.
The homicide remained unsolved until July 2011, when Ogden Police Detective Richard Childress received a letter indicating that a match had been made by the National DNA Index System between DNA evidence from the crime scene and Seamons, an inmate at the Idaho Correctional Institution south of Boise.
Childress researched Seamons and his personal identifying information through Ogden police databases, which placed him in Ogden and living in the girl's neighborhood at the time of the crime.
