Four-year-old Gus Lamont was reported missing in September.
A renewed search for missing four-year-old boy Gus Lamont has failed to uncover additional evidence.
Speaking to reporters for the first time at Oak Park Station, near Yunta, the head of SA Police's Major Crime division Detective Superintendent Darren Fielke said one of Gus's grandparents remained a suspect in the police investigation into the boy's disappearance.
Gus's grandparents, Josie and Shannon Murray, have previously released a statement saying the family had "cooperated fully with the investigation and want nothing more than to find Gus and reunite him with his mum and dad".
