Cadaver dogs have searched a water tank and a recently cemented outhouse for human remains as the five-month search for missing four-year-old Gus Lamont continues. 

The little boy was last seen playing at his grandparents’ Oak Park Station homestead near Yunta in outback South Australia on September 27.

Earlier this month, South Australian Police declared someone living at the remote station was a suspect in Gus’ disappearance and likely death.

They said the boy’s grandparents, his mother and his younger brother were at the property when he disappeared, but stressed his parents were not suspects.

Police announced this week that detectives had returned to the area to continue searching for evidence and would there for at least the next two days. 

On Tuesday, officers and cadaver dogs brought in New South Wales inspected a water tank and an outhouse at a sheep station owned by Gus’ family located 30km west of Oak Park Station. 

They then moved to a second property at Grampus, about 24km from Oak Park, where detectives were seen scouring the homestead and surrounding areas.

No evidence relating to the boy’s disappearance has yet been found during the latest search.

Police later arrested and charged Gus’s grandmother 75-year-old Josie Murray with firearm offences. The charges are not linked to the boy’s disappearance.

They were bailed to appear in Peterborough Magistrates Court in May.
