Parents of Gus Lamont 'desperate for answers' as police offer $1m for information – video

A $1m reward for information about missing four-year-old Gus Lamont is on offer, as police say they have found no evidence to suggest he is still alive. Gus's parents have made an impassioned plea for witnesses to come forward after the disappearance of their son. 'We believe someone knows something,' his father Josh Lamont said in a prerecorded message. 'Someone knows what happened to Gus and may even know where he is.'

It has been almost a year since four-year-old Gus went missing from his family’s enormous sheep farm in the South Australian outback
