A 10-year-old boy remains in “very critical” condition at a hospital in Grand Junction, Colorado, following an accident on Sunday, Nov. 26, on Interstate 70 at Crescent Junction.

Utah Highway Patrol Lt. Todd Royce said that the boy’s father was driving eastbound on Interstate 70 at about 6:08 a.m. on Nov. 26 when his 2011 Nissan Altima came up behind a slower-moving 1971 Mack dump truck in the right-hand lane.

Royce said there was a big differential in the speeds of the Nissan and the Mack truck, and the driver of the Nissan crashed into the truck near the Crescent Junction interchange.

The boy’s brother and his father were also injured in the crash, and the driver and a passenger of the Mack truck sustained bumps and bruises, according to Royce. None of the injured people’s names have been released at this time.

The crash led to the closure of Interstate 70 for about 40 minutes. A Grand County Emergency Medical Services (EMS) supervisor and two ambulance drivers responded to the scene, and according to Royce, someone had to perform CPR on the 10-year-old boy.

The boy was flown by helicopter to St. Mary’s Medical Center in Grand Junction, while two other people were transported via ambulance to St. Mary’s. Two people were also transported via ambulance to Moab Regional Hospital.

There are no indications that drugs or alcohol were a factor in the incident, and Royce said it appears that everyone was wearing seat belts.
