Helene Nikki Anderson, known as Nikki, was 27 when she and her 4-year-old daughter Adrienne were found strangled inside their Bremerton, Washington home on January 30, 1986, shortly before 9 p.m. An 8-month-old son in a nearby playpen was physically unharmed. The living room showed signs of a violent struggle—blood on the television, carpet, and couch cushions—and bruising on both victims’ necks indicated forceful choking.

Investigators reopened and re-examined the case repeatedly, formally reviewing evidence in 1993, 2003, and 2009, including DNA testing. Detectives developed multiple persons of interest over the years but no one has been charged, and the investigation remains open.

Does anyone have information about Nikki, Adrienne, or that January 30, 1986 evening in Bremerton that could help move the case forward?
