Sally Jo Tsaggaris, 46, was found dead on May 5, 1989, in a brushy area near the Tacoma Country and Golf Club in Tillicum, Washington. Her death prompted a Pierce County homicide investigation that eventually expanded into a multi-state probe.

A break came in September 1990 when authorities interviewed and arrested 38-year-old Joseph Michael Nissensohn in an Atlanta motel. Pierce County prosecutors announced plans to extradite him to Washington on charges of first-degree murder in Tsaggaris’s stabbing. Information from his estranged wife, Cheryl Rose, was reported to have been key in linking him to the killing. At the time of his arrest, Nissensohn also faced a murder charge in California and was considered a suspect in at least three other murders.

Are there anyone who knew Sally Jo Tsaggaris or who has information about her movements in 1989 who could help investigators?
