$1m reward offered as parents of missing boy Gus Lamont make emotional appeal

South Australian police and the parents of missing four-year-old Gus Lamont issued an emotional public appeal on Wednesday, asking anyone with information about his disappearance to come forward, as the state government offered a reward of up to $1m.

Gus vanished nearly a year ago from his family's vast sheep farm in the South Australian outback, and no trace of him has been found since. His mother, Jessica Murray, described the ordeal as the most devastating and inexplicable event the family has ever experienced. In a video message, she recalled Gus as a beautiful, sweet and unique boy who loved music, stories and playing outdoors, noting that during his time missing he should have celebrated his fifth birthday and his baby brother's first. His father, Joshua Lamont, said tearfully that they believed someone knew what happened to Gus and possibly even knew his whereabouts.

Search and suspect

Gus was last seen playing outside at 5pm on Saturday 27 September. Half an hour later, when his family checked on him, he was gone. His disappearance triggered one of the largest search operations in the state's history, covering the 60,000-hectare Oak Park station roughly 300km inland from Adelaide, involving volunteers, police, emergency services, defence personnel, dogs, divers, drones, aircraft and Aboriginal trackers.

Detective Superintendent Darren Fielke said 11 painstaking ground searches had so far produced no useful clues, though some anomalies spotted in aerial imagery could prompt another search. In February, police declared the case a major crime investigation and said they had identified a suspect within Gus's household — not one of his parents — after effectively ruling out the possibility that he wandered off or was abducted by an outsider.

Reward

South Australian premier Peter Malinauskas said there had been no sign of Gus, prompting the government to offer the $1m reward for information leading to a conviction or the discovery of a body. Previous state governments have offered similar rewards in past missing-children cases. The public is urged to contact Crime Stoppers with any information.
