What happens when two people suddenly vanish, when they're just gone, disappeared off the face of the earth?

People in this episode

  • Chase: Son of Bob Anderson. Chase had long been told his dad had abandoned him, and had lived a troubled life with addiction and prison time. He later found out his dad actually hadn't abandoned him, but had instead vanished in 1993 and authorities believed he had been murdered.
  • Dan: Dan was a reporter at WCCO television in Minneapolis in 1995. He flew to Wishek, North Dakota, to pursue the missing persons case, was met with hostility from the Diede family and believes he was followed around town and back to the town's airstrip. He remains haunted by the experience.
  • Dean: Bob's brother, and the last Anderson family members to see him alive. He recalled a happy family, and a childhood growing up on a hobby farm.
  • Debra: Bob's sister, who recalled how he was quiet and supportive, and how much she looked up to her big brother.
  • 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. Heather says she had a confrontation with Clyde as he visited Kristin's apartment building after she went missing — a confrontation that left her shaken and scared.
  • Molly: An advocate at Cornerstone, a domestic violence shelter and advocacy program in Bloomington, Minnesota. Molly became Kristin's case worker and helped her navigate her relationship with her estranged husband Cylde, including her pursuit of a domestic assault charge against him.
  • 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.
