Kristen Joy Diede, 30, and her boyfriend Robert Anderson disappeared after a trip to Wishek, North Dakota on August 15, 1993. They had driven from Minnesota to leave Diede’s young son and daughter with their paternal grandparents and were reported missing on August 20 when their Dodge van was found abandoned in a railroad station parking lot in Aberdeen, South Dakota, more than a hundred miles from where they were last seen.

The van had its license plates removed and the vehicle identification number scratched off. Friends reported a distressing phone call from Diede about trouble getting her children back, and the couple visited her brother after that call; none of their personal belongings were taken from their Minnesota home. Investigators at first considered a voluntary disappearance but later came to believe both Diede and Anderson were victims of homicide. Their bodies have never been found and no one has been charged.

Does anyone have information about Kristen or Robert, or recall seeing that Dodge van in August 1993?
