MYRTLE CREEK, Ore. (AP) - Oregon State Police say two women have died after apparently dropping from a bridge on Interstate 5 following a single-vehicle crash.

Police say emergency crews responded at about 2:30 a.m. Monday after the driver and her female passenger called 911 to report the crash north of Myrtle Creek on a bridge crossing the South Umpqua River.

OSP identified the two women Tuesday morning as 32-year-old Amanda J. Fuller of Roseburg and 29-year-old Stephanie N. Thomas of San Bernardino, California.

Police say crews arrived and found a 2002 Kia sport utility vehicle but not the driver or passenger.

Police say crews soon after located two woman dead on the riverbank about 80 feet below. Names haven't been released.

The incident remains under investigation.
