Police Declare Disappearance of Four-Year-Old Gus Lamont a Major Crime, Suspect Identified
South Australia Police have declared the disappearance of four-year-old Gus Lamont a major crime, stating they no longer believe he is alive. Gus was last seen on September 27 at Oak Park Station, a remote property south of Yunta. A resident of the property, not Gus's parents, has been identified as a suspect, who police report has ceased cooperation with the investigation.
Disappearance and Initial Search Efforts
Gus Lamont, aged four, was last seen on September 27 at Oak Park Station, a 60,000-hectare property located approximately 40 kilometers south of Yunta in South Australia's Mid North. He was reported missing around 5:00 PM (some sources state 5:30 PM) after playing in the sand outside the homestead. His grandmother, Shannon Murray, was the last person to see him. Gus's mother, Jessica, and another grandparent, Josie, were tending sheep approximately 10 kilometers away. The family reported his disappearance to police three hours later.
Following the report, South Australia Police (SAPOL) initiated what they described as the largest and most intensive missing person search in the state's history. Search operations involved hundreds of personnel, including police officers, Australian Defence Force members, State Emergency Service volunteers, local community members, and Indigenous trackers.
An estimated 95-square-kilometre area was searched on foot over 20 days, and a 706-square-kilometre area was covered by drones and aircraft. Investigators examined buildings, ponds, water tanks, and six disused mine shafts, some up to 20 meters deep, located between 5.5 and 12 kilometers from the homestead. Despite these extensive efforts, no evidence related to Gus's disappearance was found.
Discarded Theories and Reclassification
Initial investigations explored several theories regarding Gus's disappearance. Police initially considered the possibility that Gus had wandered off, but this theory was later largely dismissed or ruled out due to the absence of any evidence after comprehensive searches of terrain considered unlikely to conceal a body. Theories involving wild animals native to the area (dingoes, crocodiles, eagles, wild pigs) were also investigated and discounted.
The theory of abduction by a stranger was also investigated and subsequently discounted. Police cited the remoteness of Oak Park Station, a lack of evidence of external individuals or vehicles in the area at the time of the disappearance, and the exclusion of individuals with relevant risk profiles following interviews.
In October, SAPOL established Task Force Horizon to investigate the disappearance. On February 5, police officially declared Gus's disappearance a major crime, stating they no longer believe he is alive.
The investigation now focuses on two primary possibilities: Gus died by misadventure and his body was subsequently moved, or he was intentionally killed by someone known to him.
Suspect Identified and Forensic Actions
Police have identified a person residing at Oak Park Station as a suspect in Gus's disappearance. This individual, who is known to Gus, is not one of Gus's parents. Police reported that the suspect initially cooperated with the investigation but later withdrew their support.
In January, detectives executed a search warrant at Oak Park Station, conducting a forensic search and seizing items for examination. These items included a car, a motorcycle, and several electronic devices such as mobile phones, computers, and iPads. Police noted that inconsistencies were found in information and timelines provided by residents at Oak Park during interviews, particularly during the January visit.
South Australia Police Commissioner Grant Stevens confirmed that two family members of Gus Lamont are not cooperating with authorities, communicating solely through their legal representatives. Gus's grandparents, Josie and Shannon Murray, issued statements asserting their full cooperation with the investigation. Shannon Murray's legal representative stated she is cooperating through her solicitor, while Josie Murray's representative offered no further comment.
Gus's parents, Jessica and Joshua Lamont, have consistently been cleared as suspects and continue to cooperate fully with the police investigation. They have issued public appeals for information, sharing new photographs and videos of Gus, and expressed gratitude for the efforts of police and emergency services.
Ongoing Search and Related Incidents
The investigation remains ongoing, with Task Force Horizon detectives frequently returning to Oak Park Station for further searches. Recent search operations have included inspecting an outhouse with newly laid cement and a water tank on a neighboring family property approximately 30 kilometers west of Oak Park, as well as the yard and homestead of a property at Grampus, about 24 kilometers from Oak Park. A cadaver dog from New South Wales was deployed during these searches, but no new evidence was found. Police are also assessing recent significant rainfall in the region for potential new search opportunities. No formal charges directly related to Gus's disappearance have been laid.
In a separate development, 75-year-old Josie Murray, one of Gus's grandparents, was arrested and charged with firearm offenses. Police clarified that these charges are unrelated to Gus's disappearance or a previous incident involving media at the station. The charge pertains to possessing a prohibited firearm sound moderator. Josie Murray was bailed to appear in Peterborough Magistrates Court on May 6. One report indicated that Josie Murray commenced her formal gender transition in the early 2000s and was previously known as Robert 'Snow' Murray, having worked as a builder and sheep-station worker.
Community members in nearby Peterborough have expressed shock and a desire for closure regarding Gus's disappearance.
