A Moscow, Idaho, woman was killed while riding a bicycle on the shoulder of state Highway 27, just outside the Pullman city limits.
Deborah K. Budwig, 39, died Saturday after she was run over by a 1986 Ford coupe that drifted onto the shoulder. Its driver, 19-year-old James R. Martin of Moscow, was not injured.
Both the bicycle and car were heading east.
The Washington State Patrol is investigating the cause of the accident.
