Police have again returned to a remote South Australian property in a fresh bid to solve what has become one of the state’s most baffling disappearances.

On Wednesday, SA police confirmed members of Task Force Horizon would search “several locations” at Oak Park Station, which sits 43km south of Yunta, for evidence in the disappearance of four-year-old Gus Lamont.

“An update will be provided as the investigations continue,” police said in a statement on Wednesday.

It comes nearly a month after Gus Lamont’s “shattered” parents finally broke their silence, and issued a heartbreaking plea for information to help find their missing son.

“All we want is to bring Gus home and understand what happened to our beautiful boy,” they said.

Gus was last seen by his grandmother on September 27.

He was playing in the dirt near his family homestead, 43km south of Yunta, about 5pm.

Police have since declared his disappearance a major crime and revisited the property where he went missing several times in a bid to discover new clues.
