Age progression of White to 52

Christina Lee "Chrissy" White, 12, was last seen in Asotin, Washington, on April 28, 1979, at the Asotin County Fair. She called her mother at around 2:30 p.m. from a friend's house to report feeling ill from the heat. Because she did not own a car, her mother was unable to pick her up; instead, she advised Christina to rest, lay down, and apply a moist towel to her neck; then, when she felt better, to return home. Her mother assumed she had gotten better and returned to the fair when she did not phone back.[2][3]

Between 7:00 and 10:00 p.m., Christina was last seen on the 500 block of 2nd Street. She was not there when her mother arrived to pick her up. When her classmates last saw her, she was reportedly on her way home. Her schoolwork was discovered in pieces at a field outside of Asotin a few weeks after she vanished. Christina was also last seen riding her white ten-speed bicycle at the time of her disappearance.[4] It has never been located.

Senior student at the University of Idaho, Kristin Noel David, 22, was last seen on a bicycle on June 26, 1981, while travelling from Moscow, Idaho, south on U.S. Highway 95 to Lewiston, Idaho. David's dismembered remains were first found on July 4, 1981, six miles west of Clarkston, Washington, and just west of Silcott Island, in and along the Snake River. The following day, some, but not all, of the bones were discovered somewhere down the river. The body parts were wrapped in pages from several local newspaper editions from April 1981, and the remains were hidden inside black plastic bags. Clothing, other personal belongings, and David's blue 10-speed bicycle were never found.[5]

Several people who were travelling on Highway 95 the day David vanished claimed to have seen a woman who matched David's description being approached by a man in a brown vehicle on the west, or southbound, side of the road just outside Genesee, Idaho. According to additional eyewitnesses, the same man approached or interacted with various female cyclists and pedestrians on Highway 95 the same day.[6]

Kristina Diane Nelson, 21, and her stepsister Jacqueline Ann “Brandy” Miller, 18, disappeared while walking from Nelson's apartment to a grocery store in downtown Lewiston, Idaho on September 12, 1982.[7] On the same night, Steven R. Pearsall, 35, also went missing from the Lewiston Civic Theater. He asked his friends to drop him off so he could do some laundry washing and clarinet practice. He worked there as a janitor. He has not been seen or heard from since.[8] Uncharacteristically for Pearsall, he left his clarinet at the theatre. He also left an uncashed paycheck at his apartment and his car parked at a friend's house. Pearsall was well-known to both women and had a "big brother"-like relationship with them. They only lived a few blocks away from his apartment, and on their way to the store, they would have passed the theatre and may have even gone inside. Nelson had worked as a janitor at the theatre before quitting, and Pearsall took her position. Pearsall and Nelson had also both attended Lewis-Clark State College.[9][10][11]

The remains of Nelson and Miller were found March 19, 1984, in a rural area 35 miles from Lewiston near Kendrick, Idaho. Investigators were unable to determine a cause of death for Nelson, but determined that Miller had been murdered.[12][13] Pearsall was never located.[14] Investigators initially suspected Pearsall may have been involved in the Nelson-Miller abduction and murders, but later stated that all three had probably been in or near the theater at the time they vanished and were likely victims of the same killer.[15] Authorities believe it is possible Pearsall witnessed their murders and was himself killed as a result.
