Authorities say two teens were killed when an oil tank they were jumping on exploded.
Rio Blanco County Undersheriff Michael Joos says the teens were killed Saturday night at a party in the Routt National Forest about 135 miles west of Denver.
The victims were identified as 17 year old Samuel Hedemark of Phippsburg and 19 year old Christopher King Fuller of Yampa. Their bodies were found 150 yards away.
Investigators say vapor from inside the tank may have been forced out through relief valve by the pressure of the teens jumping on the top. They say a cigarette lighter may have ignited the vapor.
Joos says the tank contained 160 barrels of oil. It was not yet clear what kind of oil was inside.
Joos says a dog was also killed in the explosion, but no other injuries were reported.
