Police return to SA home of missing four-year-old Gus Lamont in search for new evidence | South Australia

After identifying the missing suspect, police returned to the home of missing four-year-old Gus Lamont to look for new evidence.

The disappearance of Gus (short for August) from his family’s remote sheep station on 27 September 2025 sparked one of the largest and most intense searches in South Australian history.

He was playing outside at 5pm, but half an hour later when his grandmother went to call him inside, he was told she was gone, police were informed.

SA police initially believed he had disappeared, based on information from people living with Gus at Oak Park Station.

Drones, divers, dogs and teams of volunteers, police, emergency services and defense force personnel searched 60,000 hectares of land around 300 kilometers inland from Adelaide and beyond.

Following advice from survival experts, hope of finding Gus alive faded and the search turned into a rescue operation.

Police have repeatedly said there is no evidence of foul play but they cannot rule out any possibility and the family is co-operating.

But police announced on February 5 that the case was now considered a major crime, claiming the suspect was someone living with Gus and that they had seized a vehicle, a motorcycle and electronic devices in mid-January.

Major crime officer Det Supt Darren Fielke said police had “identified a number of inconsistencies and discrepancies” in the information given to them by family members.

“As a result of these inconsistencies and their related investigations, a resident of the Oak Park Police Station has withdrawn his support of the police and is no longer cooperating with us,” he said.

“The person who withdrew his cooperation is now considered a suspect in Gus’s disappearance.”

Fielke said police are working on three theories: that Gus was on the loose, that he was kidnapped and that someone he knew was involved in his disappearance.

Their research revealed that the first two options were unlikely, leaving them with the third option.

Fielke emphasized that the suspect was not one of his parents.

Gus’s two grandmothers released a statement through their attorney, saying they were “devastated” that the case had now become a capital crime and that the family had “fully cooperated with the investigation and wanted nothing more than to find Gus and reunite him with his mother and father.”

On Monday, police said Task Force Horizon detectives will return to the Oak Park station and remain there for at least two days.

“Members of Task Force Horizon investigating the disappearance of four-year-old Gus Lamont on September 27, 2025, returned to Oak Park Station to continue searching for evidence,” Sapol said in a statement. he said.

“Task Force Horizon detectives are expected to remain in the area for at least the next two days.

“Updates will be provided as search activities progress.”
