A 43-year-old Richland woman died in a rollover crash Tuesday morning on Interstate 182 in Pasco, and alcohol or drugs are believed to have played a role in the wreck, the Washington State Patrol said.
Cynthia M. Bynum, 43, died at the scene. She was not wearing a seat belt and was thrown from the car, WSP said.
The driver of the car, Robert E. King, 48, of Richland, was taken to Kadlec Regional Medical Center in Richland, where he was treated and later released. He was wearing a seat belt, WSP said.
WSP said King lost control of the 1996 Saturn about 8:35 a.m. while driving east on the interstate when he left the roadway, lost control in the gravel and overturned.
WSP is investigating the cause of the crash.
