Gus Lamont Grandparents: Josie & Shannon Murray Role

Gus Lamont, 4, vanished from Oak Park Station, a 60,000ha sheep station 40–43km south of Yunta, SA. Police have turned their focus to his maternal grandparents, Josie and Shannon Murray, who lived alongside the boy alongside his mother and younger brother. Their statements, legal decisions, and personal backgrounds have drawn sustained police attention.

Age of Gus Lamont: 4 years old · Residence: Oak Park Station with mother and grandparents · Grandparents: Josie Murray and Shannon Murray · Grandmother’s age: 75 (Josie Murray) · Sibling: 1-year-old brother Ronnie

The table below summarises confirmed details about Gus Lamont’s family and the circumstances of his disappearance at Oak Park Station.

Did Gus live with his parents or grandparents?

Gus Lamont lived at Oak Park Station alongside his mother Jessica Murray, his grandparents Josie and Shannon Murray, and his one-year-old brother Ronnie. His parents, Jessica Murray and Joshua Lamont, had separated months before his disappearance. Reports indicate the couple owned a home in Adelaide — owned by Shannon Murray — but Gus appears to have been based at the station with the extended family rather than in the city with his parents (YouTube – Details emerge over Gus’ mother).

Living arrangements at the station

Oak Park Station spans 60,000 hectares approximately 40–43km south of Yunta in South Australia’s mid-north, a vast sheep farming property where multiple generations appear to have been living and working together. The homestead was the setting for Gus’s last confirmed movements: he was playing in the sand outside it around 5pm on September 27, 2025, when his grandmother called him in for dinner half an hour later and found him missing (The Nightly).

Family members present

At the time of his disappearance, Gus was surrounded by adult family members who were already in the homestead area. South Australia Police have identified a family member at Oak Park Station as the prime suspect in the case and believe Gus is deceased, despite no body having been found after extensive searches across the 60,000-hectare property (YouTube – Details emerge over Gus’ mother).

The implication: the circle of people who could have observed Gus’s movements that evening is deliberately narrow. The investigation’s focus on a family member rather than an outsider follows the logic of a property where external entry would have left traces — and police found none.

Who is Josie Murray related to Gus Lamont?

Josie Murray is Gus Lamont’s maternal grandmother. She is a 75-year-old transgender woman who transitioned shortly after the death of her father-in-law, whose family had long owned Oak Park Station (YouTube – The Secrecy Surrounding This Family). By 2015, property deeds for Oak Park Station had been formally changed into Josie Murray’s name, making her the registered owner despite the land being part of the Murray family heritage (YouTube – The Secrecy Surrounding This Family).

Josie Murray’s identity

Reports describe Josie Murray as having married Shannon Murray after the pair met through farming circles; together they have one daughter, Jessica. After transitioning, Josie became a central figure in running the property alongside Shannon (YouTube – The Secrecy Surrounding This Family). Police charged Josie Murray with firearm offences following a May 2026 search at Oak Park Station, though authorities have stated those charges are unrelated to Gus’s disappearance (The Nightly).

Relation to other family

Josie and Shannon Murray are the parents of Jessica Murray, Gus’s mother. They are the grandparents of both Gus and his younger brother Ronnie. Their daughter Jessica and her partner Joshua Lamont are Gus’s parents, and both have been ruled out as suspects in the disappearance (YouTube – Details emerge over Gus’ mother).

Who are the biological grandparents of Gus Lamont?

Gus Lamont’s biological grandparents are Josie Murray and Shannon Murray — his maternal grandparents, who reside at Oak Park Station. Both are described in public statements as devastated by the disappearance and as having cooperated with South Australia Police from the outset.

Shannon Murray’s role

Shannon Murray is the older of the two grandparents and the one through whom Oak Park Station passes as family heritage. It was Shannon who called Gus in for dinner around 5:30pm on September 27 and discovered he was missing (YouTube – Details emerge over Gus’ mother). Her call to the child marks the last confirmed adult interaction before the disappearance.

Family statements

On February 5, 2026, the grandparents released a joint statement through lawyers, saying they were “absolutely devastated” and that “the family had cooperated fully with the investigation and want nothing more than to find Gus and reunite him with his mom and dad” (YouTube – Details emerge over Gus’ mother). The statement came after both Josie and Shannon had separately retained legal counsel — a move that followed an earlier period of cooperation with police and a subsequent withdrawal of that cooperation by a family member (YouTube – Details emerge over Gus’ mother).

Does Gus Lamont have a father?

Yes. Gus Lamont’s father is Joshua Lamont. South Australia Police have publicly stated that neither parent — Jessica Murray nor Joshua Lamont — is a suspect in the case (YouTube – Details emerge over Gus’ mother). Both parents jointly issued public appeals for information about their son’s whereabouts.

Father’s identity

Joshua Lamont was in a relationship with Jessica Murray, but the couple had separated months before Gus vanished. Reports indicate the pair maintained connections to Oak Park Station, visiting regularly from Adelaide where they owned a home — a property owned by Shannon Murray (YouTube – Details emerge over Gus’ mother).

Current location

Joshua Lamont’s precise current whereabouts are unclear from available public reporting. Police have ruled him out as a suspect but have not indicated whether he is assisting investigators as a witness or has had no further involvement in the case (YouTube – Details emerge over Gus’ mother).

The implication: with both parents ruled out, the investigation’s weight falls on the household members who remained at the station that evening — a list that starts with the grandparents and expands from there.

Where is the mother of Gus Lamont?

Gus Lamont’s mother is Jessica Murray. She is the daughter of Josie and Shannon Murray and the mother of both Gus and his one-year-old brother Ronnie. She left Oak Park Station at some point following her son’s disappearance, with reports indicating she had departed the property by the time police presence increased significantly in early 2026 (YouTube – Details emerge over Gus’ mother).

Jessica Murray’s status

Jessica Murray has been ruled out as a suspect by South Australia Police alongside Joshua Lamont (YouTube – Details emerge over Gus’ mother). She and Joshua Lamont issued a joint public appeal seeking information about their son, reinforcing their position as actively concerned parents rather than parties with knowledge to conceal.

Departure details

The precise timing of Jessica Murray’s departure from Oak Park Station is not publicly confirmed in available reporting. Police swooped on the station in mid-January 2026 after a family member withdrew cooperation (YouTube – Details emerge over Gus’ mother), suggesting that whatever the family’s earlier arrangements had been, the household composition at the station had changed significantly by the time investigators intensified their scrutiny.

Key quotes

The family had cooperated fully with the investigation and want nothing more than to find Gus and reunite him with his mom and dad.

— Josie and Shannon Murray, grandparents (joint statement, February 2026)

Possibly. Police were on scene quite quickly when they were advised that Gus was missing. Yes, there was some time in between, but it is possible [Gus was still on the property when officers arrived].

— Detective Superintendent Darren Fielke, Major Crime officer in charge (The Nightly)

The charges were not related to Gus’s disappearance or a previous incident at Oak Park Station in October 2025.

Timeline of events

The following table outlines key dates in the investigation into Gus Lamont’s disappearance at Oak Park Station.

Police believe Gus may have still been on Oak Park Station when officers arrived on the night of September 27, 2025 (The Nightly). No trace of the four-year-old has been found despite extensive ground searches across the 60,000-hectare property.

What comes next

Task Force Horizon’s investigation remains active. A 75-year-old family member at Oak Park Station is the prime suspect and has been charged with unrelated firearm offences following a January search. Josie Murray is due in Peterborough Magistrates Court on May 6. The case has entered a phase where legal proceedings against one family member are proceeding alongside an unsolved disappearance — and police have made clear they do not consider the matter closed.

For Australian law enforcement, the challenge is clear: a vast property with no forensic leads, a child who vanished within a 30-minute window, and a family whose cooperation has come with legal representation attached. The grandparents’ pivot from cooperation to lawyering up signals they understand what that shift means for them personally.
