A 17-year-old girl was killed early today when she lost control of her sport-utility vehicle in Black Forest, authorities said.

The wreck happened at about 2:50 a.m. on Brentwood Drive at Pinery Drive. Her vehicle, a Ford, ran off the left side of the road, rolled and partially ejected her, the Colorado State Patrol said in a news release. She was not named.

Three teenage passengers were taken to Memorial Hospital as a precaution.

Alcohol and drugs are not believed to be factors, the news release said. The crash is under investigation by the state patrol's accident reconstruction team.
