In Part 4, the investigation into Joli Truelson's 1972 murder takes us back to Minneapolis — and to evidence the police destroyed.

Joli died after being struck in the back of the head with what investigators believed was a hammer. We examine whether Harvey Carignan was ever a suspect in her killing, and explore the other murders he is suspected of committing.

At first, 25-year-old Isadora Wengel was considered a missing person. Yet days into the 2026 investigation, the Fargo Police Department pivoted and charged her boyfriend, 21-year-old Joshua Hite, for her murder.

Based on evidence collected, investigators believe Isadora Wengel was likely dismembered.

Despite the murder charge, Isadora Wengel's remains have not been located. They are asking people in Ottertail County, Minnesota to keep their eyes out for a 27-gallon tote with a red lid.

Specifically, they believe she could be found in Fergus Falls, Battle Lake or Elizabeth.

At the time of publication: Hite has not been convicted.

To clarify: Law enforcement has not definitely determined Joshua Hite was driving the Suburu Impreza spotted in Fergus Falls in the early hours of Jan. 7, 2026.

If you know anything about the murder of Isadora Wengel, contact the Fargo Police Department at (701) 235-4493

In the third and final part of this series, we explore what happened to the mountain of evidence in the 1984 cold case murder of Kelly Jean Robinson -- and we discuss what could come next in law enforcement's investiation into Kelly's death.

Kelly's body was found floating in a rural Minnesota gravel pit pond, roughly 30 miles from her home in Sioux Falls. Her case remains unsolved.

If anyone has any information on the murder of Kelly Jean Robinson, please contact the Minnesota Bureau of Criminal Apprehension at 1-877-996-6222.

In part 2 of this series, the team at The Vault tries to track down a man previously considered a potential suspect in the 1984 murder of Kelly Jean Robinson. In the process, they run across a new potential person of interest: a convicted murderer who preyed on South Dakota workers in the 1980s. He was a free man in 1984 -- and he was known to frequent The Frontier Bar, where Kelly Robinson was last seen leaving.

Forty years after a 22-year-old woman was found floating in gravel pit pond in rural Minnesota, a man who was adopted as an infant took two at-home DNA tests. The results led him to the discovery that his biological mom was Kelly Jean Robinson, the woman found dead in the pond. She had been murdered, and her case had gone cold.

In coordination with Kelly's family, the team at The Vault obtained the investigative file, which included never-before-released information. New suspects emerged. Details about her autopsy were exposed. And, for the first time, Kelly's family learned a very critical fact in this case: a semen sample, obtained through the autopsy, was taken into evidence. The real question now is, where did it go?

In this episode, Trisha Taurinskas takes listeners behind the scenes of the investigative process behind the The Vault's most recent web series, "Minnesota Vice," through an interview with the author: Jeremy Fugleberg.

The series focuses on the story of Casey Ramirez, a drug smuggler who tried to hide out while living large in a little Midwest town. It examines how the feds caught up with him, and what happens to a small town's soul when it decides it won't ask too many questions.

The arrest of a well-known Winona resident in the 2011 cold case death of a newborn baby found floating in the Mississippi River stunned the community.

Jennifer Baechle is a pillar in the local arts and music scene. She's a wife and mother of two, who volunteers with nonprofits and cooks for church fundraisers, including one benefiting the Winona Immigration Network. She's an English instructor at Winona State University, her alma mater.

Forensic geneology led investigators to Baechle's door, with concrete DNA evidence indicating Baechle is the mother. Yet the community is still left with one big question: Why did she wrap her baby in a tote bag and send her down the Mississippi River?

In this episode, we speak with John Molseed, a Rochester Post Bulletin reporter who has been covering the story -- and has insight into the small city's reaction to it all.

Press conference audio was provided by the Rochester Post Bulletin, a Forum Commnications newspaper.
