Todd Alexander Rudiger, 29, and his partner Donna Gene Ferguson, 18, were found murdered at their Portland trailer home after their families became concerned when they could not be reached. Both victims were white and had been living together in the trailer; the killings occurred on July 17, 1992.

Authorities identified the perpetrator as Sebastian Alexander Shaw, who was later arrested and convicted for multiple murders, including the slayings of Rudiger and Ferguson. Shaw was sentenced to life in prison without the possibility of parole. The case attracted attention because forensic evidence and investigative work linked Shaw to additional homicides before and after the couple’s deaths.

Anyone who knew Todd or Donna, or who has information about their lives in Portland before July 17, 1992, is asked to come forward.
