A Colorado Springs couple is dead and their son and friend seriously injured following an accident near Telluride this weekend.

Daniel Gluklick, age 50, and his 47-year-old wife, Jeanine, died Saturday when their Jeep rolled about 800 feet down a mountain at Imogene Pass.

Cole Gluklick, age 11, and his 7-year-old friend, Ian Nordstrom, were injured. No one was wearing a seat belt, and all four were thrown from the vehicle.

Authorities say the Jeep pulled over to let another car pass on the narrow road, but one side of the vehicle lifted after rolling up on some rocks while trying to get back on the road. The Jeep then rolled off the embankment.

The couple is survived by two teenage daughters.

Daniel Gluklick did classified work for the military. Jeanine Gluklick ran a day-care center at their home, and had taken care of Nordstrom since he was a baby.
