Betty Pratt, 55, and her 60-year-old husband Harold were found murdered at their campsite roughly 75 miles southeast of Phoenix, west of Oracle Junction. The couple had been camping in the desert in December 1981; their bodies were discovered by hunters on December 10, 1981, after they were killed on December 9.

Investigators later connected the killings to a wider series of shootings across Arizona, Oregon, and California carried out between 1970 and 1982. The suspected perpetrator in those linked cases was identified as Robert Wayne Danielson Jr. The discovery of the Pratts’ bodies became a significant piece of the broader investigation into that suspected serial violence.

Who knew Betty and Harold, or was in the area that weekend and might remember anything about vehicles, people, or unusual activity near Oracle Junction in early December 1981?
