The Beaumont Brothers: Disappearance in Broad Daylight

The Beaumont Brothers: Disappearance in Broad Daylight: The Kidnapping of Jane, Arna, and Grant Beaumont

Three children disappear at 12:15 PM on the busiest beach in Adelaide on Australia Day, in front of hundreds of people. Jane bought cakes with money her mother never gave her, and an unknown blonde man was seen with them minutes before vanishing without a trace.

In this episode, we explore the inconsistencies that persist 58 years later: four main suspects with partial confessions, excavations that found only trash, and fake letters that tormented the parents. The police never prosecuted anyone, although a teenager wrote two pages in 1968 confirmed as a cruel joke in 1992.

Victims: Jane, Arna, and Grant Beaumont
Date: January 26, 1966
Location: Glenelg Beach, Adelaide, Australia
Status: Unsolved

- The money for cakes appeared without explanation: Jane paid with one Australian pound when Nancy only gave 6 shillings and 6 pence.
- Arna had mentioned days earlier that Jane had "a boyfriend" at the beach, suggesting prior contact with the blonde man.
- Excavations in 1968, 2013, and 2018 searched for three bodies, but the parapsychologist Gerard Croiset pointed to a warehouse that turned out empty after 40 thousand dollars of searching.
- Andrew McIntire wrote in his diary that his father and Alan Munro arrived nervously with blood in the car that afternoon, but without material evidence, Munro was never prosecuted.
