The grandfather of four-year-old Gus Lamont, who remains missing, has been fined $10,500 by South Australian authorities. The fine stems from the possession of an illegal gun silencer discovered at the family property in Oak Park Station, a remote area in the state’s far north. Police confirmed the firearm offence is unconnected to the ongoing search for young Gus Lamont. The investigation into the silencer was separate from the missing person case. Authorities have not released further details regarding the circumstances of the silencer’s discovery. The search for Gus Lamont continues, with police maintaining they are pursuing all available leads. The family has been cooperating with both investigations.
