The grandparent of missing South Australian four-year-old Gus Lamont has been charged with having a prohibited gun silencer.
Police on Monday arrested Josie Murray, 75, at the family’s remote Oak Park sheep station, about 40km south of Yunta.
Murray briefly attended the local police station and was charged with one firearm offence, before being released to front Peterborough Magistrates Court on May 6.
Officers had been on the station as part of a two-day search – one of several that have been conducted on the property since Gus vanished on September 27 last year.
He was last seen playing on a mound of dirt near the family’s homestead about 5pm.
Acting Officer in Charge of Major Crime Investigation Branch Detective Inspector Andrew Macrae said that the charge is not connected to the disappearance of the four-year-old or an incident with a journalist on the property in October 2025.
