Police have mobilized every resource in the desperate hunt for Gus Lamont.

Cadaver dogs, drones, and helicopters are combing abandoned tunnels and mineshafts for any sign of the boy.

Officials say the terrain and hidden spaces make the search extremely challenging.

The newly released images have investigators focused on a potentially chilling clue.

Neighbors and family are watching anxiously, hoping for a breakthrough.

And one chill

Police will return to Oak Park Station for the second day as part of a renewed three-day search for evidence in the case of missing four-year-old Gus Lamont.

On Tuesday, police said the search was prompted by recent heavy rainfall in the area.

Officers yesterday returned to the remote station near Yunta, in South Australia’s Mid North, as part of their continued investigation into Gus’s disappearance.

Gus was reported missing from his family’s vast property eight months ago, on September 27 last year.

Task Force Horizon members — including specialist Major Crime detectives and STAR Group officers — will search numerous locations on the property as part of the latest sweep of the area.

“The searching has resumed to take advantage of opportunities that may have arisen as a result of recent heavy rains on the property,” police said in a statement yesterday.

“An update will be provided as the investigations continue.”

According to the Bureau of Meteorology website, the Yunta airstrip received almost 23 millimetres of rain over two days from May 16 and May 17, and a further 4mm on May 19.

Another 4mm was recorded at the airstrip on Monday.

Police have previously said the ongoing probe into Gus’s disappearance is “one of the largest, most intensive and most protracted searches ever undertaken” in the state.

Their efforts have involved a drone with infrared capabilities, aircraft, mounted officers, SES volunteers, a First Nations tracker, a cadaver dog and Australian Defence Force members, yet no trace of him has been found.

In February, SA Police’s Major Crime Investigation Branch Detective Superintendent Darren Fielke said police had ruled out the initial theory that Gus had wandered off and said there was “no evidence, physical or otherwise to suggest that”.
