Gus Lamont: Renewed search at Oak Park Station for missing four-year-old concludes with no new evidence

South Australia police have concluded a renewed search for missing four-year-old Gus Lamont.

The new search followed heavy rainfall in Yunta, which was expected to provide “new opportunities” in the investigation.

Sadly, police revealed on Thursday that no new evidence had been found.

According to police, the dedicated search team Task Force Horizon combed through “several areas” but “sadly did not locate any evidence”.

“Task Force Horizon members have not ruled out further activity at Oak Park Station in coming weeks as the investigation continues,” police said.

It comes after Gus’ disappearance was deemed a “major crime” in early February. The little boy has been missing from his family’s outback property since September 27.

Police were told that he was last seen playing outside at about 5pm and when his grandmother tried to call him inside at about 5.30pm, the boy had vanished.

On February 5, detective superintendent Darren Fielke confirmed that investigators “don’t believe, now, that Gus is alive”.

“This is one of three investigation options that have been explored by the members attached to Taskforce Horizon,” he said.

Having ruled out the theories that Gus had wandered or been abducted, police are pursing a line of enquiry into their third theory — that someone known to the boy was involved in his disappearance and suspected death.

Police have ruled out his parents as being involved in his disappearance, but have confirmed publicly that two members of Gus family are “not-cooperating” with investigators.

“We can confirm that two family members are only communicating via their legal representatives,” a police spokesperson said. “We are unable to comment any further.”

Andrew Ey, the lawyer representing Gus’ grandmother Josie Murray, was asked by The Advertiser if his client had anything to say on the matter.

According to that masthead, Mr Ey said “there’s no further comment at this stage”.

Casey Isaacs, the lawyer of Gus’ grandmother Shannon Murray, said she “is co-operating through her solicitor”.

In the weeks following his disappearance, a 94 sq km radius around the Oak Park Station property was scoured by all available emergency services, SES, the ADF, and an army of volunteers in addition to aerial searches conducted by drones and helicopters.

Anyone with any information on Gus Lamont’s disappearance is urged to contact Crime Stoppers 1800 333 000.
