SA police said they have inspected an outhouse with fresh cement and a water tank as part of the latest search for Gus Lamont in South Australia’s Mid North.
Police have concluded a two-day search with no evidence found so far.
The second day of the search focused on a neighbouring property owned by Gus’s family, about 30 kilometres west of Oak Park Station, where the four-year-old disappeared almost five months ago.
Police told the ABC that Task Force Horizon detectives this morning scoured a remote area on a sheep station, and inspected a water tank and an outhouse where cement had recently been laid.
A cadaver dog trained to detect human remains has been brought in from New South Wales.
They then moved to a property at Grampus, about 24 kilometres from Oak Park, where major crime detectives scoured the yard and homestead.
In a statement, police said the latest search covered numerous buildings and structures at Oak Park Station and at several locations adjoining the property.
“Unfortunately, no evidence was located during the intensive searches,” police said.
“Task Force Horizon detectives have not ruled out returning to Oak Park Station as the investigation continues.”
Police to maintain presence in region
Earlier, a police helicopter departed the Peterborough Aerodrome for the Pualco Range Conservation Park, south of Yunta.
The search has concluded today, but the ABC understands police will stay in the area.
Yesterday, police arrested and charged Gus’s grandmother, 75-year-old Josie Murray, with firearm offences they say are not linked to the boy’s disappearance.
The grandmother is expected to appear in the Peterborough Magistrates Court in May.
Gus was reported missing on September 27, 2025, and police have searched the area on several occasions since.
His disappearance was declared a major crime on February 5 by police, who said a person residing at Oak Park Station was a suspect, but stressed that person was not one of Gus’s parents.
The next day Gus’s grandparents, Josie and Shannon Murray, issued a statement saying the family had “cooperated fully with the investigation”.
At that same press conference earlier this month, police said a vehicle, a motorcycle and electronic devices were seized during a search at the family’s station a month ago, on January 14 and 15.
