A search is underway in southwest Colorado for two missing boys – a 14-year-old and a 12-year-old.

The pair, from Telluride, have been missing since Sunday, when they were on an outing with their father and step-father, according to the San Miguel County Sheriff’s Office.

They were last seen on County Road 20R, also known as the Dolores River Road, between 11 a.m. and 4 p.m. near a boat ramp.

“They have no extra clothes, no food and no water,” said Aaron Ihinger, father of the 12-year-old Christopher.

Ihinger said he was rock-climbing with Eric Wright, a climbing partner, and the two boys were waiting at the trailhead, near Ihinger’s pickup truck.

The sheriff’s office described Wright as 14-year-old Danny Eberly’s stepfather.

At one point during the climb, Ihinger noticed that the truck was gone. The two men frantically climbed off the rock formation and high-tailed it back to the trail head.

“They were playing on the river, bouldering and having fun,” Ihinger recalled. “I don’t know if they took off on a joy ride or what.”

The keys were hidden in an accessible place on the truck, Ihinger said, that the pair knew about, so they could have access to the cab if needed.

When Ihinger got back to the spot — a pull-off on the county road — the truck and the boys were gone.

A cooler, which had been filled with drinks and food, was left beside the truck in a shady spot. The food and drinks were scattered about. Ihinger said his wallet, with cash and credit cards, was inside the truck.

The two men left the area on foot, looking for help, and the boys, as they went. They were eventually picked up by a passerby, a man who was bear hunting in the area, and they drove to Norwood and contacted the sheriff’s office for help about 7 p.m.

So far, the credit cards have not been used anywhere, Ihinger said. He is searching for the boys, or clues to their whereabouts, with members of the sheriff’s office.

Christopher Ihinger, 12, is about 5-feet 4-inches tall and 130 pounds, he has brown hair. Danny Eberly, 14, is about 5-feet 5-inches tall and 100 pounds with brown hair.

Christopher was wearing a black t-shirt and pants with a black and yellow baseball cap. Danny was also wearing a baseball cap.

The truck is described as white Ford F150 four-door crew cab, with Colorado license plate 801 RBH. It has a ding, about the size of soccer ball and an inch deep, on the right rear door.

If anyone sees the boys, or the truck, or knows the boys whereabouts, they should call the San Miguel County Sheriff’s Office at 970-728-1911 immediately.
