Martin Lee Sanders

Sanders became a suspect in the murders in 1989 after he confessed to his cellmate about the murders of Rima and Marks, revealing details about the murders that only the perpetrator would know. The inmate told authorities about Sanders' confession, and Sanders was extradited to Washington to face trial the next year. In order to avoid the death penalty, he plead guilty to the two murders and received a life sentence. He now resides at the Coyote Ridge Correctional Center in Cornell, Washington.

On May 18, 1986, Sanders, using an unloaded gun and handcuffs, kidnapped two hitchhikers in Missoula, Montana. He raped one of the victims in the sleeping compartment of his semi-truck. He was soon arrested for this crime and sentenced to 20 years in prison the following year.

On the evening of May 20, 1983, Sanders murdered Rhonda Rima and Elizabeth Marks, two 15-year-old girls. The two were last seen at the Lilac Festival carnival in Spokane, Washington. Three weeks after their disappearances, their bodies were discovered in the Spokane River.

Sanders is also suspected of murdering Marsha Weatter, 18, and Kathy Allen, 19 – two hitchhikers who were shot to death in Grant County between late March and early May 1980.
