EUGENE – Authorities have identified two women who died after falling from a bridge on Interstate 5 following a single-vehicle crash.

The Register-Guard reported that 32-year-old Amanda Fuller, of Roseburg, and 29-year-old Stephanie Thomas, of San Bernardino, California, fell off the bridge early Monday.

Oregon State Police said emergency crews responded 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.

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

The two women were later found dead on the riverbank below.

State police spokesman Capt. Bill Fugate said troopers are still working to determine why the women fell off the bridge.
