Anchorage police have identified the three occupants of an SUV involved in a rollover early Thursday morning that left one dead.

Police say Brandon Muller, 17, was pronounced dead at the scene Thursday morning.

Damien Doctolero, 18, remains in critical condition, while Chynna Tiernan, 16, suffered severe injuries but is in stable condition.

Police say the families of the teens have been notified.

Police say a preliminary investigation found that "none of the occupants were wearing seat belts and that excessive speed contributed to the severity of the crash."

APD spokesperson Jennifer Castro stressed that the crash was still under investigation and that excessive speed "does not mean the crash was caused by a high rate of speed."

Police say the collision remains under investigation and encouraged members of the public with information related to the crash to contact the Anchorage Police Department Traffic Unit at 786-8830.
