Police say a suspect has been identified in the disappearance of a four-year-old boy, Gus Lamont, who went missing in the South Australian outback.


Gus, who was last seen playing outside his home on a remote sheep station near Yunta, vanished on 27 September. His grandmother left him alone for about half an hour before discovering he was missing, prompting a massive search effort that remains one of the largest in the state's history.


Authorities have reported that a resident on the property has been designated as a suspect, but have clarified that Gus's parents are not involved in the investigation.


The police's search efforts covered an area of approximately 470 sq km, roughly double the size of Edinburgh. In late October, as searches tapered off, a 12-member taskforce was formed to further investigate the case.


This taskforce has reviewed statements given by family members, revealing various inconsistencies about the timeline of events surrounding Gus's disappearance.


Detective Superintendent Darren Fielke has confirmed that as a result of these inconsistencies, the individual at the Oak Park station has ceased their cooperation with law enforcement. However, the focus remains squarely on finding Gus. 'We will continue to thoroughly and meticulously investigate until we achieve a resolution,' Fielke stated.


Authorities had considered several scenarios regarding Gus's disappearance, including the possibility that he could have wandered off or been abducted, but have since ruled out the likelihood of either occurring in this remote region.


Efforts to recover Gus and bring him home safely continue, as authorities remain committed to uncovering the truth of this troubling case.
