"Even if it's one tiny little piece, that might be the only thing we'll need," said Casey Lee, a sister of Amy Wroe Bechtel.
Lee, her sister, Jenny Newton, and Fremont County Sheriff's Investigator Dave King were scheduled to appear this morning on the "Geraldo Rivera Show" along with relatives of three other missing people.
Bechtel has been missing since July 24, when she went jogging along the Loop Road in the Shoshone National Forest near Lander.
Lee said the show would focus on people who have been missing from one to 18 months.
"Obviously it was incredibly tragic to be there with other people going through the same thing, and on the other hand, in a horrible sense, it was comforting to know that we were not alone," Lee said. "What was really interesting was seeing the different stages of family trauma that people are in, depending on how long their loved ones have been missing."
Meanwhile, the reward offered through the Amy Wroe Bechtel Recovery Fund for information leading to closure of the case has been doubled to $100,000 thanks to the efforts of her brother's employer, SHL Aspen Tree President Brooks Mitchell of Laramie.
Bechtel's brother Nels Wroe said Mitchell put up $25,000 of his own money toward the reward and recovery fund, and Aspen Tree's parent company SHL matched it.
Wroe said this month he will launch a pledge drive in an attempt to raise up to $500,000 for the fund.
King said on Monday, he flew over the search area near where Bechtel's car was found, but saw no sign of the 25-year-old woman. He said the snow cover would allow him to see signs indicating a body.
King said during taping of the show, Rivera questioned him about the role Steve Bechtel, Amy's husband, may have played in her disappearance.
Steve Bechtel, 27, has not cooperated with federal and local law enforcement authorities since early August, when, he said, an FBI agent accused him of killing his wife.
Bechtel has vehemently denied any involvement. King said he told Rivera that Bechtel's refusal to cooperate with authorities do not prove anything.
"That doesn't mean we think he did it, that doesn't mean I'm accusing him of anything, but if anyone is holding up the progress of the investigation, it's Steve," King said.
King said investigators plan to return to the search area in the spring, but said there has been no progress in the case.
He said he hoped the appearance on national television could spur a flow of calls to his office.
"The biggest thing it would accomplish is it would introduce this case to people who have never known Amy Wroe Bechtel," he said.
