Gus Lamont: Mystery deepens amid police update eleven months after little boy vanished from Oak Park Station

Eleven months after Gus Lamont vanished from his family’s remote South Australian property, police are no closer to finding the four-year-old.

Gus vanished without a trace from a family homestead at Oak Park Station, about 275km north-east of Adelaide. He was last seen on September 27, 2025.

His disappearance triggered one of South Australia’s largest and most intensive missing-person searches involving police, SES volunteers, defence personnel, specialist teams, aircraft, the dog squad and Indigenous trackers who combed the expansive zone for any trace of Gus.

Despite eleven large-scale searches over a near-year period, the police force said on Wednesday they had still found “no evidence” to determine what happened to little Gus.

Initially, detectives believed the four-year-old may have wandered away from the homestead while playing outside.

But after extensive searches failed to establish a direction of travel, investigators ruled out this theory and declared the case a major crime.

Task Force Horizon officers continue to investigate whether the little boy was abducted from the cattle station, or if a person known to him was involved in his disappearance.

In February, one of Gus’ grandparents was identified by police as a suspect in the case, but detectives stressed his parents’, Jessica Murray and Joshua Lamont were not.

When asked by The Nightly if any suspects were being investigated, police declined to provide any new information on who they believe was involved. No one has been charged in relation to Gus’ disappearance.

In an emotional tell-all interview with 7NEWS in June, Josie Murray spoke publicly for the first time about Gus’ disappearance, saying police told her they believed she may have been involved in his disappearance.

“They think that I buried him, took him out and buried him. That’s all they’ve said so far,” she told Spotlight.

“It’s ludicrous. It just doesn’t make sense. Why would you inflict what’s happening to us now?”

Ms Murray said she denied any involvement in the little boy’s disappearance.

“We absolutely know we’re innocent,” she added.

“We know that we couldn’t and didn’t do anything and the hard part obviously is to convince other people of that. There’s no way of completely convincing people.”

Ms Murray said the little boy’s heartbreaking disappearance had taken an enormous toll on the family.

“I’d be in tears and I know Shannon (Josie’s former partner, who still lives with her on the property) said the same thing, that you’d just suddenly be hit by the horror, the enormity of this,” Ms Murray said.

“And then to be accused of doing something like this is just — you could not wish a more horrible experience on anyone.”

As part of the extraordinary multi-search effort to find Gus, investigators scoured the property and surrounding land including water infrastructure and mine shafts.

A dam near where Gus was last seen playing on a dirt mound was drained and examined but failed to result in a breakthrough.

Despite the efforts of those involved, the only physical clue uncovered by investigators so far has been a single small footprint located about 500m from the home.

“Task Force Horizon has and will continue to investigate any and all information, including information provided by Gus’s family, that could assist in identifying what has happened to Gus,” a South Australia Police spokesperson said in a statement provided to The Nightly.

For Gus’ family, the approaching anniversary will mark almost a year of uncertainty and the one unanswered question: Where is Gus Lamont?
