A Tri-State Care Flight helicopter transported at least one person to a regional medical facility Saturday afternoon after a motorcycle crash on U.S. Highway 550 near Bondad.
Authorities on Tuesday did not give a condition report on the person or people injured.
A motorcyclist from Gunnison was riding behind the motorcycle involved and witnessed the collision. Daryl Cunningham said the man driving the motorcycle ahead of him was driving north just past the New Mexico border when he was cut off by a dark-colored sport utility vehicle turning onto the highway near the intersection with County Road 310.
The motorcyclist hit the driver-side passenger door of the other vehicle and flew about 30 feet, said Cunningham. About six other drivers pulled over, called emergency personnel and rendered aid.
"He never twitched a muscle as far as I could tell," said Cunningham, who added that the man was partially covered with a blanket at the scene.
Cunningham said he and the injured motorcyclist were driving close to the speed limit at the time of the accident.
A dispatcher for the local office of the Colorado State Patrol said the accident involved two Native Americans on a motorcycle and that a helicopter was called in to transport the injured, but directed all other questions to the Southern Ute Police Department, which handled the investigation because of the subjects' tribal affiliation. Because the state patrol assisted at the scene, it didn't give the incident a case number and no incident report was filed.
Messages left with the tribal police on Saturday, Sunday and Tuesday were not returned. Messages left with the La Plata County Sheriff's Office were also not returned. A spokesman for Care Flight said the organization does not release flight information to the media.
Authorities would not confirm whether the man was still alive.
