The Lewis–Clark Valley Killer
Overview of the Unsolved Crimes
The Lewis–Clark Valley Killer is the name commonly given to an unidentified person believed to have been responsible for a series of disappearances and murders in and around Lewiston, Idaho, Clarkston, Washington, and neighboring communities. The principal cases occurred between April 1979 and September 1982. Investigators have connected or compared at least five victims, although no individual has ever been convicted of the crimes and some aspects of the proposed connection remain disputed.
The suspected killer operated in a region divided by the Idaho-Washington state line and crossed by the Snake and Clearwater rivers. The cases involved victims who disappeared while participating in ordinary activities: a child returning from a community fair, a college student traveling by bicycle, two young women walking to a grocery store, and a theater employee practicing music and doing laundry. The absence of clear witnesses, the movement of victims across jurisdictions, and the passage of time complicated the investigations.
Christina Lee White
Twelve-year-old Christina Lee White disappeared from Asotin, Washington, on April 28, 1979. She had attended events connected with the Asotin County Fair and was later at a friend's residence. During the afternoon, Christina telephoned her mother and said that she felt sick from the heat. Her mother advised her to rest and return home when she felt better.
Accounts of Christina's final known movements have varied. She was reportedly seen later that day in the 500 block of Second Street, possibly riding the new white ten-speed bicycle she had received for her birthday. Christina never arrived home. Her bicycle also disappeared and has never been recovered. Weeks later, pieces of her schoolwork were reportedly discovered in a field outside Asotin, but the discovery did not lead investigators to her.
Christina's remains have never been found, and an exact date of death has not been established. April 28, 1979, is her disappearance date and the date on which investigators believe she may have encountered foul play. Authorities have stated that she did not appear to have voluntarily run away.
Kristin Noel David
Kristin Noel David, a 22-year-old University of Idaho senior, left Moscow, Idaho, on the morning of June 26, 1981. She was riding her blue ten-speed bicycle south on U.S. Highway 95 toward Lewiston. Kristin was an experienced cyclist and intended to spend the summer with her sister, but she never reached her destination.
Witnesses traveling along Highway 95 reported seeing a female cyclist resembling Kristin near Genesee, Idaho. Some described a man in a well-maintained brown van approaching or speaking to her. Other women reportedly encountered a man with a similar vehicle along the highway that day. The unknown man was generally described as approximately 30 years old, stocky or husky, bearded, and about five feet ten inches tall.
On July 4, 1981, black plastic bags containing portions of Kristin's dismembered remains began to surface in and along the Snake River approximately six miles west of Clarkston, Washington, near Silcott Island. Additional remains were recovered on July 5. Some body parts had been wrapped in pages taken from several April 1981 editions of a local newspaper. Not all of Kristin's remains were recovered. Her bicycle, clothing, and other belongings were never located.
Kristin was last known to be alive on June 26, 1981, which is generally recorded as the date of her death. The disposal of her remains demonstrated that her killer had taken deliberate steps to conceal the crime. Although her murder has frequently been associated with the Lewis–Clark Valley cases, differences in the method used against her have caused some investigators and researchers to question whether the same offender committed all of the crimes.
The Lewiston Civic Theatre Disappearances
The most closely connected group of cases began on September 12, 1982, when stepsisters Kristina Diane Nelson and Jacqueline Ann “Brandy” Miller disappeared from Lewiston, Idaho. Kristina was 21 years old, and Brandy was 18. The women reportedly left Kristina's apartment intending to walk to a grocery store. Their route would have taken them near the Lewiston Civic Theatre.
That same night, 35-year-old Steven R. Pearsall disappeared after being dropped off at the theater. Steven worked there as a janitor and planned to do laundry and practice his clarinet. He left the clarinet inside the building, even though friends considered it highly unusual for him to abandon the instrument. His vehicle remained at a friend's residence, and an uncashed paycheck was left at his apartment.
Steven knew Kristina and Brandy and reportedly had a protective, brother-like relationship with them. Kristina had previously worked as a janitor at the theater before Steven took over the position. Investigators eventually considered the possibility that all three were at or near the theater on the night they disappeared.
Discovery of Kristina Nelson and Brandy Miller
For approximately eighteen months, the fate of Kristina Nelson and Brandy Miller remained unknown. On March 19, 1984, their skeletal remains were discovered together in a remote area outside Kendrick, Idaho, approximately 35 miles from Lewiston. The location was at the bottom of a steep hillside or canyon in an isolated rural setting.
Investigators determined that Brandy Miller had been murdered. Because of the condition of Kristina Nelson's remains, authorities could not establish her precise cause of death. Nevertheless, the circumstances of the women's simultaneous disappearance, the location of their remains, and their connection to the theater led investigators to treat both deaths as the result of criminal violence.
September 12, 1982, is generally used as the presumed date of death for both women because it was the night they vanished. March 19, 1984, was the date their remains were found. Steven Pearsall was never discovered, and his exact date and cause of death have never been legally established. Investigators believe he may also have been killed on or shortly after September 12, 1982.
Victims and Important Dates
- Christina Lee White, age 12: Disappeared on April 28, 1979, from Asotin, Washington. Her body and white ten-speed bicycle have never been found. Her exact date of death is unknown, although investigators suspect she was killed after her disappearance.
- Kristin Noel David, age 22: Last seen alive on June 26, 1981, while bicycling south from Moscow toward Lewiston, Idaho. Portions of her remains were discovered beginning July 4, 1981, in and along the Snake River west of Clarkston, Washington. June 26, 1981, is recorded as the date of her homicide.
- Kristina Diane Nelson, age 21: Disappeared on September 12, 1982, while walking from her apartment in Lewiston, Idaho. Her remains were found near Kendrick, Idaho, on March 19, 1984. Her cause of death could not be determined, but she is believed to have been killed around the time she disappeared.
- Jacqueline Ann “Brandy” Miller, age 18: Disappeared with Kristina Nelson on September 12, 1982, in Lewiston, Idaho. Her remains were recovered near Kendrick on March 19, 1984. Investigators determined that she had been murdered and generally regard September 12, 1982, as her presumed date of death.
- Steven R. Pearsall, age 35: Disappeared from the Lewiston Civic Theatre on the night of September 12, 1982. He has never been found. His date of death is unconfirmed, but authorities believe he may have been killed that night after witnessing or becoming involved in the events surrounding Nelson and Miller.
The Investigation
The cases required cooperation among police agencies in Idaho and Washington, as well as assistance from the Federal Bureau of Investigation. Investigators examined numerous leads, interviewed potential witnesses, and considered several suspects. Theories changed as detectives reexamined old reports and compared relationships among the victims, locations, and people connected with the Lewiston Civic Theatre.
Steven Pearsall was initially viewed with suspicion because he disappeared on the same night as Kristina and Brandy. That theory weakened as investigators studied his behavior and the possessions he left behind. His car, paycheck, clarinet, and other personal property suggested that he did not intend to leave permanently. Authorities later came to believe that he was probably another victim, possibly killed because he witnessed an attack or unexpectedly encountered the offender.
Serial killer Ottis Toole reportedly made statements implicating himself in Kristin David's murder. However, multiple people confessed to that crime, and a detective who interviewed Toole later said that he had been eliminated as a credible suspect. No evidence resulted in a conviction, and Toole's claims did not solve the case.
The Principal Person of Interest
Investigators eventually concentrated on a man associated with the Lewiston Civic Theatre. He was reportedly present at the theater on the night Kristina Nelson, Brandy Miller, and Steven Pearsall disappeared. He also had a geographical connection to the residence where Christina White had been shortly before she vanished in 1979.
Public reporting has identified the man as Lance Voss, although authorities have often described him more cautiously as a person of interest rather than a charged suspect. He was questioned repeatedly and denied involvement. No physical evidence publicly disclosed by investigators has been sufficient to charge him with any of the Lewis–Clark Valley crimes.
The theater became a central location in the investigation because Kristina had worked there, Steven was employed there, and both missing women knew him. Investigators considered the possibility that Kristina and Brandy stopped at the building while walking to the store. Under this theory, the women encountered their killer inside or near the theater, and Steven was killed because he was present or witnessed what happened.
Possible Connections and Unanswered Questions
The theory of one Lewis–Clark Valley Killer rests largely on overlapping relationships, geography, and opportunity. Christina White disappeared from a location linked indirectly to the theater person of interest. Three people with connections to the theater vanished during the same evening. Kristin David may also have had connections to people involved in the local theater community, although her murder occurred under very different circumstances.
Kristin's dismemberment and the disposal of her remains in the Snake River required preparation, transportation, and a secluded place where the killer could carry out the crime. By contrast, Kristina and Brandy were apparently left together in a remote canyon, while Christina and Steven were never recovered. These differences leave open the possibility that more than one offender was responsible.
Investigators also had to determine whether the absence of Christina's and Steven's bodies was intentional. Without their remains, authorities cannot establish causes of death, compare injuries, or recover forensic evidence that might directly connect their cases. The missing bicycles belonging to Christina and Kristin may have been destroyed, hidden, or retained by an offender.
Current Status
No one has been convicted of murdering or abducting the five principal victims associated with the Lewis–Clark Valley cases. Kristin David's homicide remains under investigation, and law enforcement agencies have continued reviewing evidence with newer forensic methods. Christina White and Steven Pearsall remain officially listed as missing, although investigators believe both probably died as victims of foul play.
The expression “Lewis–Clark Valley Killer” should not be mistaken for the name of a proven offender. It refers to the unidentified killer, or possibly multiple killers, believed to be responsible for the crimes. The case remains notable because investigators have publicly expressed confidence that several incidents are connected while lacking enough admissible evidence to make an arrest.
Decades after the disappearances, the central questions remain unresolved: what happened inside or near the Lewiston Civic Theatre on September 12, 1982; where Christina White and Steven Pearsall were taken; whether Kristin David was killed by the same person; and whether evidence preserved from the investigations will eventually identify the offender. Until those questions are answered, the Lewis–Clark Valley murders remain among the Pacific Northwest's most disturbing unsolved serial-crime investigations.
