Kristin Diede was 30 when she and her boyfriend, Robert Anderson, disappeared on August 15, 1993, while visiting Wishek, North Dakota. The couple had driven there to drop Kristin’s two children with their paternal grandparents and intended to return to Minnesota; they never made it home.

They were last reported to have spoken with a highway patrol officer about child custody laws before vanishing. Five days later their van was found abandoned in Aberdeen, South Dakota, about 100 miles away; the VIN had been scratched off and the license plates removed. Investigators later treated the case as suspicious and have not located Kristin or Robert. Kristin was in the midst of a divorce at the time, and her family has disputed any theory that she left voluntarily.

Does anyone remember seeing the van or the couple in eastern North Dakota or Aberdeen around August 15–20, 1993?
