"At this point, it's nice to get any extra help we can," said Steve Bechtel. "We were really glad when we learned of their interest."
"We've tried for over a year to contact them, but their schedule doesn't exactly fit with ours," he said.
Amy, 25, disappeared July 24, 1997, while running in the mountains near Lander.
A six-member film crew for "Unsolved Mysteries" recently spent four days in the Lander area, interviewing Steve, other relatives, friends and searchers.
The show will feature re-enactments of the events surrounding Amy's disappearance. The re-enactments will be filmed in Utah with actors not close to the case.
"'Unsolved Mysteries' has way more experience with missing person cases than any of us," said Bechtel. "It's not just a story. They're not just looking for controversy and gossip. Their ratings are based on their success at solving mysteries. If they find somebody, their ratings go through the roof, so that's what they aim for."
The show is hosted by Robert Stack, who visited Lander a few years ago to compete in the One Shot Antelope Hunt.
The segment is expected to air either in early November or sometime in February.
The 15 months since Amy disappeared have been difficult, Bechtel said.
"I still am really frustrated that the world doesn't stop," he said. "The bills don't stop, the seasons keep changing. For me, I'm still stuck in July (of last year)."
"A lot of people are telling me to move on. Everyone's giving me advice," Bechtel said. "How do you move on when there's still no closure? We still have to keep working to find Amy ... until something is resolved."
Bechtel said he's not ready to resign himself to the idea that Amy might never return.
"It's going to take some resolution to make a step," he said. "If there was a divorce or someone was killed in an auto accident, you realize that phase of your life is over. But I still have Amy's clothes sitting in a dresser. I still have her glasses and her toothbrush in the medicine cabinet, like it's waiting for someone to come home from a trip."
Bechtel said women need to be carry pepper spray or even a gun with them and not go alone into remote areas and he worries that the perpetrator may still be in the Lander area.
"I just hope it doesn't happen to anyone else, because it's no good living through this."
