Australia Day. January 26, 1966. Jane (9), Arnna (7), and Grant (4) Beaumont caught the bus to Glenelg Beach in Adelaide, Australia — alone. They had done it before. It was a five-minute ride. Their mother expected them home by noon. They never came back. Witnesses saw the three children on the beach in the company of a tall, thin stranger in his mid-thirties. He bought them lunch. He played with them on the sand. Then they were gone. Police launched the largest search effort in Australian history at the time. The beach was searched. A nearby marina was drained. Interstate roads and airports were monitored. Nothing. No trace of the children was ever found. No bodies. No clothes. Not one of the 17 items they had with them that day. ─────────────────────────────── 60 YEARS LATER — THE CASE IS STILL OPEN. A $1 million reward has been offered by the South Australian government. The man on the beach was never identified. ─────────────────────────────── The disappearance of the Beaumont children changed Australia forever. Parents who never thought twice about letting their kids play outside unsupervised suddenly realized the world was not as safe as they believed. Jane. Arnna. Grant. Still missing. Still no answers. The full investigation — including the suspects, the mysterious letters, and the $1 million reward — is coming soon. Follow the channel so you don't miss it.
