Four-year-old Gus Lamont vanished on 27 September from a remote South Australian sheep station, and as the first anniversary of his disappearance approaches, his grandmother has unveiled a controversial new theory: that he was abducted by a wedge-tailed eagle. Gus's grandmother, Josie Murray, plans to search eagle nests on the property despite acknowledging the theory is "highly unlikely" but "not impossible." This development adds a fresh dimension to a case that has puzzled investigators, as extensive police, military and volunteer searches have failed to locate any trace of the child.

Police previously concluded that someone known to Gus—living at Oak Park Station, 300 kilometres north of Adelaide—may have killed him, deliberately or accidentally. Josie Murray has been identified as the main suspect, though she maintains her innocence and no charges have been laid. The investigation, which has involved over 11 police searches of the station, became classified as a major crime investigation in January, and the working relationship between the grandmother and police deteriorated following this development. Gus's parents lived separately, a two-hour drive away from the remote homestead.
