January 26, 1966. Adelaide, Australia. Three children from the Beaumont family – nine-year old Jane, seven-year old Arnna and four-year old Grant – leave their residence in order to travel to the beach in the suburb of Glenelg, but they never return home. A number of eyewitnesses report having seen the children in the company of an unidentified man before they went missing and this person is believed to be responsible for their disappearances. Over the years, investigators explore a number of potential suspects and perform excavations at various locations, but no trace of Jane, Arnna or Grant is ever found. This week, “The Trail Went Cold” will be releasing the first part of a special two-part episode about one of the famous mysteries in the history of Australia: the disappearance of the Beaumont children. Special thanks to listener Kristen Rodway for narrating the opening of this episode.
