Police say a suspect has been identified over the disappearance of a four-year-old boy who went missing in the South Australian outback. Gus Lamont was last seen playing outside his home on a remote sheep station near Yunta, about 300km from Adelaide, on 27 September. His grandmother left him alone for about half an hour before checking on him, only to find the boy missing, prompting one of the largest land and air searches in the state's history.

Police have confirmed that a person residing on the property is the main suspect; however, they stated that Gus's parents are not under investigation. After the boy was reported missing, extensive searches covered roughly 470 sq km around his home but yielded no clues. In late October, a dedicated taskforce was appointed to continue the investigation, sifting through statements from the family that revealed inconsistencies.

Detective Superintendent Darren Fielke stated that a resident at Oak Park station has stopped cooperating with police. Investigators are considering three possible scenarios regarding Gus's case: walking off, abduction, or involvement from someone familiar to him. Because of the property's remote location, police have ruled out abduction as well as the likelihood that Gus merely wandered off. They assure that efforts to find him will persist until a resolution is found.
