In the summer of 1992, 18-year-old Donna Gene Ferguson was found murdered alongside her 28-year-old boyfriend, Todd A. Rudiger, in their Southeast Portland mobile home. Their fathers discovered both victims on July 20; each had been stabbed in the neck. Investigators determined Donna had been bound and raped before her death. The couple had planned to marry the following year.

The case initially produced no suspects and went cold. A DNA match ultimately broke the investigation: DNA from a 1995 Southeast Portland rape matched evidence from the Ferguson-Rudiger crime scene. After police obtained a discarded cigarette in 1998 and matched that DNA to the murder scene, Sebastian Alexander Shaw was arrested. He later pleaded guilty in 2000 to the murders and the 1995 rape and received two life terms.

Does anyone have memories of Donna, Todd, or the neighborhood around Southeast Portland in 1992 that could add context to what happened?
