Kristin Noel David was 22 and a senior at the University of Idaho when she left her Moscow apartment on June 26, 1981, for a bicycle ride to Lewiston. Witnesses later placed a woman matching her description on Highway 95 near Genesee, where a man in a well-kept brown van with yellow plates was seen approaching female cyclists and pedestrians that day.

Kristin never reached Lewiston. On July 4, 1981, dismembered remains identified as hers were recovered in black plastic bags floating in the Snake River about six miles west of Clarkston, Washington; some remains were wrapped in pages from April 1981 local newspapers. Her blue 10-speed bicycle, clothing and other personal items were never found.

Investigators described a primary suspect as a white male about 30 years old in 1981, roughly 5 feet 10 inches with a stocky build and a possible brown or reddish beard. Authorities have examined links to several unsolved Lewis-Clark Valley cases from 1979 to 1982; tips have included a false confession by Ottis Toole and a person of interest connected to the Lewiston Civic Theater, but no arrests were ever announced. The FBI and local law enforcement say the case remains active and some evidence has been retested with newer technology.

Did anyone who rode Highway 95 that summer or who remembers a brown van with yellow plates see something that could help investigators?
