APACHE JUNCTION, Ariz. -- The red car left behind at the First Water Trailhead of the Superstition Mountains belongs to Kenny Clark of Gilbert, last seen on the trails Sunday morning.
When Roy Triebel heard about search on TV, he realized he and his girlfriend were two of the last people to see Clark.
"I'm like, that red car was in the parking lot!" said Triebel."It was just all starting to add up."
He said they saw Clark around 9:30 a.m. Sunday.
"We stopped and talked to him for about two to three minutes," he said. "I asked him where he was going and I said, 'Where you headed to?' and he said 'Oh, I just want to see how far I can get.'"
Triebel said the 56-year-old was covered in sweat and alone, and when they parted ways, he couldn't help feeling concerned.
"On the way back, I told my girlfriend I really want to go back and tell that guy to turn around and we talked about it the whole way back."
His gut feeling was right. Clark never came home, and search and rescue crews combed the trails to find him.
"We've done that search and nothing has come up," said Officer Chris Hegstrom with Maricopa County Sheriff's Office. "So now we're going to spread that search out a little bit. We're going to take those trails but go off the beaten path.
Triebel wants to help to bring Kenny Clark down from the mountain, like he wishes he'd done Sunday morning.
Clark's wife Heather spoke to 3TV off camera, and said she believes Kenny had about a gallon of water with him that day.
She also said Clark knew he was expected to pick up his grandson. S
Search teams from Pinal and Maricopa counties say they'll continue searching until Clark is found.
