The parents of missing South Australian four-year-old Gus Lamont have issued a plea for information about the disappearance of their son, releasing a new photo and video of him. Gus Lamont went missing from his Oak Valley Station home in the state's outback on September 27 last year. His parents, Josh and Jess, have today urged anyone with information about his disappearance to come forward, sharing their grief and devastation. Our lives have been shattered, and every moment without him is unbearable," they said in a statement shared by South Australia Police. "We are united in our search for answers about what happened to our little boy, Gus, who means everything to us... we know someone out there may have information. If someone knows what happened, we are pleading with that person—or anyone who may have seen or heard anything—to please come forward. "Even the smallest detail could give us the answers we so desperately need."
