Lynne Brown, 25, was last seen in Estacada, Oregon, on February 22, 1975, after leaving her ex-husband’s home with her two young children, seven-year-old Leslie and five-year-old Geoffrey, for what was supposed to be a single-day visit with their mother. The children were not returned, and nearly three weeks later, on March 12, 1975, Leslie and Geoffrey were found dead in a clearing at McIver Park, lying on a coat and each having suffered two gunshot wounds to the head.

Lynne’s Volkswagen Beetle was located abandoned in the park the same day; shell casings were found inside and a receipt for a .38 caliber revolver was recovered. Lynne was not located and has not been seen or heard from since February 22, 1975. Reports say investigators focused on Lynne as the primary suspect, citing prior mental health issues, a past suicide attempt, and alleged threats against the children if custody changed. A warrant for her arrest was reportedly issued in October 2006.

Many questions remain about what happened to Lynne after she left with her children and who was responsible for Leslie and Geoffrey’s deaths. If anyone has information about Lynne Brown’s whereabouts in 1975 or afterwards, please share what is known.
