How do two people vanish? What blanked news of missing couple Kristin Diede and Bob Anderson

How do two people just disappear? How does that happen and not trigger a massive manhunt, blanket TV coverage, cable news coverage and some sort of Netflix documentary show? In the case of Kristin Diede and Bob Anderson, it was about who they were. Or perhaps more so – who they weren’t.

How do two people just disappear? How does that happen and not trigger a massive manhunt, blanket TV coverage, cable news coverage and some sort of Netflix documentary show?

In the case of Kristin Diede and Bob Anderson, it was about who they were. Or perhaps more so – who they weren’t.

Welcome to Dakota Spotlight - Season 6, Episode 7: How Two People Vanish.

In this episode, co-producers James Wolner and Jeremy Fugleberg continue their investigation into the 1993 unsolved disappearance of Minnesota residents Kristin Diede and Bob Anderson on a road trip to Wishek, North Dakota.


They’ll take a close look at all the fault lines, all the big cracks, that seemed to swallow up Kristin and Bob and the news of their disappearance, effectively squelching the hunt for them.

We do know Kristin’s friends and Bob’s family in Minnesota alerted local authorities after the two disappeared, reporting them to two different local police departments.

But it seems no local or state law enforcement in North Dakota got a similar report. Nobody there heard about Kristin and Bob going missing from the Wishek area until late 1994 - more than a year after they vanished. And in neighboring South Dakota, Bob's van had been discovered but had made into a city service vehicle. Nobody seemed to realize it was an important piece of evidence.

Meanwhile, Cylde, Kristin's estranged husband, visited Kristin's apartment building in Bloomington and while there, Kristin's friend Heather recalls she got into a confrontation with him, one that left her shaken and scared.

In March 1994 — about six months after Kristin and Bob were last seen — Clyde divorced her and got full custody of their two children, Mitchel and Deanna. Kristin, who remained missing, wasn't at the divorce hearing to contest custody, or anything else for that matter.

Clyde later moved to Winner, South Dakota, and opened a chiropractic practice there. Then in December, Bloomington police made an important phone call, one that powers the investigation to this day.

People in this episode

  • Brenda: Kristin's sister, who recalled her sister enjoying cards and other games, and remembered hearing about Kristin and Bob going missing not long after returning from a trip over the weekend Kristin disappeared.
  • Clyde: Kristin's estranged husband. They married in 1983 and had two kids together, Mitchel and Deanna. 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. Later, a friend of Heather claims she had a confrontation with him outside Kristin's apartment in Bloomington. In March 1994, Clyde got a divorce from Kristin and obtained full custody of their two children. Later that year he moved to Winner, South Dakota, and opened a chiropractic practice.
  • Diane: Bob's sister, who shared numerous memories of her brother, and their family — including a father who promoted education and told her she could do what she aspired to do in life. Diane and her husband Mike have kept careful notes and gathered information over the years about the missing persons case.
  • Heather: A neighbor of Kristin in Bloomington, Minnesota. She and a friend, Tiffany, befriended Kristin, helped coax her out of her shell after her marriage to Clyde had collapsed, and were the first to report her missing to law enforcement.

  • Sherri: Kristin's niece, who explained that Kristin had grown estranged from the Goebel family. She mentions that after years of uncertainty, it's hard to keep up hope Kristin is alive.
  • Susan: Former executive director of Cornerstone, a domestic violence shelter in Minnesota, where Kristin sought help. Susan has been a steadfast advocate for Kristin's case. She points out that many people often vanish with little media attention or public interest, including Indigenous and Black women, and that poverty is a factor as well, including for missing white women such as Kristin.
  • Tiffany: A neighbor of Kristin Diede in Bloomington, Minnesota. She and friend Heather befriended Kristin. Tiffany was the last person Kristin was known to have called before vanishing with her boyfriend, Bob. She later reported them missing to Bloomington police and felt blown off.
