Steven R. Pearsall was 35 when he was last seen in Lewiston, Idaho, on the evening of September 12, 1982. A former U.S. Air Force corporal who worked as a janitor at the Lewiston Civic Theater, Pearsall was dropped off after a retirement party; his girlfriend watched him unlock the theater door, step inside and turn on a light. He planned to do laundry and practice his clarinet but never returned home and his body has never been found.

Pearsall vanished the same night as 21-year-old Kristina Nelson and her 18-year-old stepsister Jacqueline Brandy Miller, who left their apartment a few blocks from the theater and also never returned. Nelson and Miller’s bodies were found two years later in a steep canyon near Kendrick and ruled homicides.

Investigators have linked Pearsall’s disappearance to a string of Lewis-Clark Valley crimes, including the 1979 disappearance of 12-year-old Christina White and the 1981 murder of 22-year-old Kristin David. A man connected to the theater emerged as a person of interest and in 1995 police identified a prime suspect who worked with Pearsall and admitted sleeping at the theater the night Pearsall vanished; that person has not been publicly named and no arrests have been made. Did anyone in Lewiston at the time know Pearsall’s routines at the theater or see him after he was dropped off?
