A teenage girl from southern Alberta is dead after police say she was hit by a pickup truck west of Rocky Mountain House.

Police and ambulance were called to Hwy 11, also known as the David Thompson Highway, about 40 km west of Rocky Mountain House on Friday night around 9:45 pm. RCMP say the pickup was heading east when it hit the 14-year-old, who was walking on the highway near a parked SUV.

The driver stopped to offer help, but a fight broke out between the driver and people inside the SUV. The SUV occupants collected the injured teen and headed east towards Rocky Mountain House. The SUV entered the ditch, where police found them.

Police say several of the occupants had been drinking. The 14-year-old, who is from the Eden Valley Reserve west of Nanton, Alta., died before paramedics could take her to hospital.

The driver of the pickup was treated at the Rocky Mountain House hospital and released.

RCMP continue to investigate the collision Sunday.
