Victoria Rhone, 32, was found dead inside a train in a Portland rail yard on February 19, 1991. Her death was ruled a homicide by strangulation; investigators reported she had been tied up with the killer’s own shirt, a key piece of evidence left at the scene.

Investigators later linked her case to that of Rheena Ann Brunson, killed months earlier. Scott William Cox, a long-haul truck driver, became a suspect after coming to law enforcement’s attention in connection with an assault and rape in Seattle. Cox eventually confessed to both Portland murders, but a judge ruled the confession inadmissible because it had been improperly obtained. Prosecutors proceeded using DNA evidence tying Cox to the killings.

On September 15, 1993, Cox pleaded no contest to two counts of murder and received consecutive terms with lifetime post-prison supervision; he was paroled five years early in 2013 under then-applicable laws. Cox has been considered a prime suspect in numerous other unsolved murders across the country. Did anyone in Portland around 1991 see or hear anything that might still help clarify Rhone’s last movements?
