Four-year-old Gus is missing in South Australia's outback (SA Police)
Four-year-old Gus Lamont went missing from a sandpit at his family's sheep station in South Australia on Saturday, 27 September.
A massive search operation involving hundreds of personnel, drones, and sniffer dogs was launched but has since been scaled back, with police stating his survival is unlikely.
Authorities found a shoe print similar to Gus's 500 metres from the property, but the trail went cold without further evidence.
Police have investigated theories including Gus wandering off or an animal attack, while a criminologist suggested possible third-party involvement, though no suspects have been named.
The disappearance has gripped the nation, leading to public support, but also the spread of fake AI images and unfounded online theories implicating the family, which a family friend described as "heartbreaking".
