OGDEN -- Gregory L. Seamons wasn't initially on police radar as a potential suspect in the 1983 rape and slaying of 11-year-old Rebecca Lemberger, an Ogden detective said Tuesday.
However, now that police have obtained DNA evidence linking Seamons, 45, to the crime, they want help from his associates or former classmates regarding his whereabouts around the time Lemberger was beaten to death.
"Maybe they have been holding on to (information) for the last 30 years that always was curious to them," Ogden Police Detective Sgt. Tim Scott said.
Anyone with information about Seamons, who was 15 at the time of Rebecca's slaying, is asked to contact the lead investigator in the case, Ogden Police Detective Richard Childress, at 801-629-8348.
About a half-dozen people have come forward to provide police with a timeline for Rebecca, from her disappearance March 2, 1983, when she left home to walk to Edison Elementary School at 935 E. 1050 North, and the discovery of her body the next day in a shed west of 729 N. Mountain Road in Ogden.
"We've got an idea of everything the victim did," Scott said.
Rebecca died as a result of blunt force trauma to the head. The autopsy also determined she had been sexually assaulted.
A candlelight vigil for Rebecca will be held at 7 p.m. Friday at Ben Lomond Cemetery, 526 E. 2850 North, North Ogden.
Although there were a number of suspects during the initial police investigation, Seamons wasn't considered a person of interest at the time the crime was committed, Scott said.
The homicide was considered a cold case until July 2011, when 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 Rebecca's neighborhood at the time of the crime.
Ogden police have obtained an arrest warrant for Seamons for the first-degree murder and rape of Rebecca.
Authorities will also investigate whether Seamons may be a suspect in other local unsolved crimes, Ogden Police Lt. Scott Conley has 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 from prison in 2017.
It hasn't been determined whether Seamons will waive or fight extradition from Idaho to Utah to face charges in Rebecca's slaying.
"We don't have a concern about him walking out of prison (in Idaho)," said Scott, adding that police are patiently awaiting Seamons' extradition.
