The search is on for 62-year-old Richard "Dick" Martin, of Corbin, who was last seen riding his red A.T.V. behind his home, Monday morning, in the Bee Creek area, near Laurel Lake.
"It's been nerve wracking. There's been no word, no nothing," said Tammy Jackson, Martin's sister-in-law and family spokesperson.
More than 24 hours of searching by land and air and there's still no sign of Martin, and search crews say things are getting trickier in the dense Daniel Boone National Forest.
"The trails are wet, water all over them, and it's muddy," described Ricky Fore, the Major of the Rescue squad.
"It makes it rougher for us, especially when the fog rolls in," added Danny Moses, Director of Whitley County Emergency Management.
Even more dangerous, Martin battles crippling arthritis, a reason why his family says he typically never rides alone. This time he did because his family said he was wanting to clear his mind.
"Going on his four wheeler kind of took his mind of his pain," said Jackson, adding that Martin was always sure to come back in before dark.
Searchers have worked hour after hour scouring trails, searching for clues, and even tracing Martin's cell phone, but no luck thus far.
"We haven't [found any clues] and that's very unusual. Normally, we'll find something to go on," said Moses.
"It's pretty difficult," said Fore of the search, "we try to find the path that he's [Martin] been taking, and all of the other four wheelers going in and out covers his trail. So it's kind of hard to track him that way."
As time slips away, so does the family's hope for some shred of good news.
"We wish he would just walk in through the back door and tell us what happened," admitted Jackson.
Still Martin's family and the searchers refuse to call it quits. They will resume the tracking process around 10 a.m. Wednesday and they hope to have more resources.
