Susan Libby Marable was 34 and living in Yakima, Washington, when she disappeared on the evening of April 23, 1991. At about 9:30 p.m. she left the van where she was staying with a friend to walk to a nearby store and told the friend that if she wasn’t back in two hours, something was wrong. She never returned.

Witnesses reportedly saw Susan get into a maroon pickup truck in the same parking lot where she had been abducted and raped in 1990. The man convicted of that attack, John L. Robinson, had threatened her in court during his sentencing weeks before her disappearance; he was incarcerated at the time. A bartender said the truck seen that night belonged to John Robinson’s brother, Bill Robinson, who was never interviewed by police and died in 1992.

At the time she vanished Susan wore a denim jacket, blue jeans, tan clogs with white soles and a single silver unicorn earring. Foul play is suspected, and her family has continued to seek answers and closure.

Did anyone in Yakima or who knew Susan have information about the maroon pickup or where she might have gone that night?
