OGDEN -- Formal paperwork has been filed to begin the process of returning Gregory L. Seamons to Ogden to stand trial in a cold-case murder and rape police say were solved by DNA testing.
Seamons, 45, is charged with rape and murder in the 1983 death of 11-year-old Rebecca Lemberger, of Ogden.
Seamons has been an inmate at the Idaho State Correctional Institution in Boise since 2007 following a conviction for second-degree kidnapping. He is scheduled to complete his sentence in December 2017.
In letters to the media since he was formally charged Sept. 28 in 2nd District Court in Ogden, he has proclaimed his innocence, saying the DNA is likely that of his late father.
That scenario was called virtually impossible by the Utah State Crime Lab, which conducted the DNA testing of Seamons.
An "Interstate Agreement on Detainers," dated Nov. 29, has been sent to Idaho prison officials signed by Weber County Attorney Dee Smith and 2nd District Judge Ernie Jones to attest to the charges against Seamons and document the evidence against him.
A copy was formally added to Seamons' case file in 2nd District Court on Monday.
In the IAD, Smith agrees "that immediately after trial is completed in this jurisdiction I will return the prisoner directly to you or allow any jurisdiction you have designated to take temporary custody."
The 14-page document includes no time frame for Seamons' transport to Ogden for arraignment on the charges, and Smith, in an interview, said no schedule has been given by Idaho officials.
"He's an inmate in Idaho, and we're taking the steps necessary to have him sent here for prosecution."
Normal extradition is more complicated for Seamons because he's in prison, Smith said, and likely has a hearing before Idaho penal authorities to complete the process.
Seamons faces a sentence of life in prison in Utah if convicted of raping and killing Lemberger. She was last seen at 8 a.m. March 2, 1983, when she left home to walk to Edison Elementary School at 935 E. 1050 North. She never made it to school.
The next day, Lemberger's body was found in a shed in a field west of 729 N. Mountain Road in Ogden.
She had been sexually assaulted and died as a result of blunt force trauma to the head.
Ogden police say Seamons' DNA matches evidence from the crime. Seamons was 15 and lived in Lemberger's neighborhood at the time of her death, detectives say.
