"Unsolved Mysteries" has decided not to come to Leavenworth County today to tape a story on the mysterious disappearance of high school senior Randy Leach.
The prime-time television show is delaying its arrival to conduct additional research into Leach's disappearance, researcher Chip Selby said.
"The story has been put on hold for now," Selby said. "We're investigating claims made by Lee Harper and all the other stuff going on. We're trying to see if there's any truth to any of this stuff."
The taping may be postponed for one or two months, Selby said.
Harper is Harry Lee Harper, who initially identified himself as Terry Martin, an investigative journalist, to news reporters in August.
Harper said he has uncovered evidence that Leach was killed by a Satanic cult in Leavenworth County. He alleged the group killed dozens of people and dealt drugs with impunity for years. Leavenworth Sheriff Herb Nye has said Harper's allegations are false.
Leach was a 17-year-old Linwood High School senior when he disappeared at an April 1988 graduation party. Interest in his disappearance reignited in August when Leavenworth County law enforcement officials questioned three men and then released them.
Leach's mother, Alberta, said she and husband, Harold Leach, are disappointed that "Unsolved Mysteries" has put off coming to Leavenworth County.
"We want them out here, if it means getting something to help find Randy," she said. "They're all we've got going for us.
"We're just sitting and waiting, like we have for the last five years. It's about all we can do."
Meanwhile, the Kansas Bureau of Investigation is continuing to investigate how records from the Leavenworth County sheriff's office on the Leach investigation apparently were leaked to Harper.
The KBI investigation, requested by Nye, could take "at least a couple of weeks" to complete, special agent George Schureman said.
