FORT MORGAN, Colo. (CBS4) – Two Fort Morgan teens who died in a crash while going the wrong way on Interstate 76 suffered broken necks, according to the coroner.

Sally Ann Trammell, 19, and Josephine Raquel Juanes, 18, were killed after their vehicle struck a construction barrier on Aug. 9.

Morgan County Coroner Don Heer said that both teens test positive for alcohol, which may have been a factor in the crash.

“The car crash is what caused them to die,” the coroner said.

Trammel was driving the car at the time of the crash. Both were wearing seat belts, according to the Colorado State Patrol.
