MURDERED: Jennifer Farber Dulos

62m

When Jennifer Farber Dulos vanished after dropping her five children off at school in New Canaan, Connecticut, on May 24, 2019, all eyes were on her estranged husband, Fotis Dulos. And when investigators found surveillance footage showing Fotis suspiciously stopping at multiple trash cans in a nearby city and throwing things just hours after she disappeared, a massive hunt for evidence kicked off, and a conspiracy involving at least two other people began to unfold. Six years later, one suspect is dead, one is in prison, and one is awaiting trial... But what exactly happened to Jennifer, and where her body is, remains a mystery.

UPDATE: On Friday, June 13, 2025, the conspiracy to commit murder charge against Kent Mawhinney was dropped in the case of Jennifer Farber Dulos’s death. He has instead pleaded guilty to lesser charges. For more details, head to the Crime Junkie Fan Club!

MYSTERIOUS DEATH OF: Jeannette Bishop May & Gabriella Guerin

68m

In 1980, the ex-wife of a British aristocrat and her Italian friend vanished from a small ski resort town during a snowstorm in the mountains of central Italy, and investigators had a simple theory—they got lost and had some kind of accident. But when mysterious messages arrive, clues lead them on a decades-long deep dive into the art world jet set, the mafia underworld...and even the Vatican.

If you have any information about the deaths of Jeannette Bishop May and Gabriella Guerin, you can email the local prosecutor’s office in Macerata, Italy, at procura.macerata@giustizia.it.
And if you or anyone you know is thinking about suicide, please be aware that emotional support can be reached by calling or texting the Suicide & Crisis Lifeline at 988.
