The disappearance of Kristin Diede and Bob Anderson is the focus of the latest season of Dakota Spotlight, an investigative true crime podcast from Forum Communications: "Vanishing Act: The Untold Story of Kristin Diede and Bob Anderson."

The podcast's live investigation into this missing-persons case spanned North Dakota, South Dakota, Minnesota and elsewhere.

In the latest episode of Dakota Spotlight, the podcast digs into what happened in the days immediately after Kristin and Bob were last seen, specifically to Bob's van, in which the couple drove to Wishek North Dakota, where they were last seen. The podcast also leaps ahead to 2015 for a crucial meeting between Bob's family and law enforcement, to discuss the missing persons case.

Inside Episode 6: 'Follow the Van'

Then a blogger, future Dakota Spotlight podcast creator James Wolner had befriended Bob's family and was nearby in a diner in Napoleon that day in September 2015, waiting to hear what the family members learned from law enforcement about the case.

When the family member crossed the street to the diner, they had big news for James about something that had taken place in Aberdeen, about 100 miles away from Wishek.


Aberdeen was where, just a few days after Kristin and Bob disappeared, police got a report about an abandoned van left in a parking lot. It was Bob's van, the one he and Kristin drove to North Dakota — a potentially crucial piece of evidence.

The family members also had another big piece of information they had learned from authorities: Clyde, Kristin's husband, had stayed at a hotel in Aberdeen, just before the van was found. And the location of the hotel could be significant.

People in this episode

He was convicted of 5th-degree domestic assault against Kristin, and issued a no-contact order for her, in May 1993, three months before she vanished. Law enforcement told family members in 2015 that Clyde had stayed in a hotel in Aberdeen, South Dakota — just about 100 miles away from Wishek — just after Kristin and Bob disappeared and shortly before Bob's van was found abandoned just a few blocks away. Clyde denied to Dakota Spotlight he had done so.
