In the summer of 1992, the life of 18-year-old Donna Gene Ferguson, a White / Caucasian female, was tragically cut short in her Southeast Portland, Oregon mobile home. On July 20th, she and her 28-year-old boyfriend, Todd A. Rudiger, were discovered murdered by their fathers. The scene that confronted them was one of brutal violence; both had been stabbed in the neck. Further investigation would reveal that Donna had been bound and raped before her death. The couple, who had plans to marry the following year, were victims of a seemingly random and senseless act.
For years, the double homicide remained unsolved, leaving the families of Donna and Todd without answers and a community in fear. The initial investigation yielded no suspects, as there was no apparent connection between the victims and their killer. The case grew cold, a painful open wound for those who knew and loved the young couple. The break in the case would not come from a direct lead in the murder investigation, but rather through the persistent work of law enforcement and the power of DNA evidence in an unrelated crime.
The path to identifying the killer began to unfold in 1995 when police investigated a rape in Southeast Portland. DNA evidence was collected from that crime scene, and in 1997, the Oregon state crime lab made a startling connection: the DNA from the 1995 rape matched the DNA found at the scene of the Ferguson-Rudiger murders. This crucial link pointed investigators to one man: Sebastian Alexander Shaw. In 1998, after obtaining a discarded cigarette from Shaw and matching his DNA, police arrested him. Faced with the evidence against him, Shaw eventually pleaded guilty in 2000 to the murders of Donna Ferguson and Todd Rudiger, as well as the 1995 rape. He was sentenced to two life terms for the murders. It was later revealed that Shaw was a serial killer, responsible for at least one other murder and a suspect in more.
