The Beaumont Children, Part I-A Summer Day in Adelaide

On January 26, 1966, three siblings — Jane (9), Arnna (7), and Grant (4) Beaumont — boarded a bus to Glenelg Beach in Adelaide, Australia.

They were seen. They were spoken to. They were last observed walking away from the beach with a man witnesses described as calm, well-dressed, and familiar with the area.

They were never seen again.

In Part I of our two-part series, The Midnight Mystery Archive reconstructs the final known hours of the Beaumont children — minute by minute — using original newspaper reporting, South Australia Police timelines, and eyewitness accounts.

This episode explores:

• The family’s routine on the morning of January 26 • The children’s bus trip to Glenelg • Verified sightings at Colley Reserve and Mosley Street • The man witnesses reported seeing with the children • The unexplained one-pound note used to buy food • The moment concern turned into a missing persons report • The first nighttime police searches along the coast

Told in a calm, narrative style and grounded in contemporaneous sources, this episode focuses not on speculation — but on what can actually be established about the day three children disappeared in plain sight.
