On January 26th, 1966, nine-year-old Jane Natare (born September 10th, 1956), seven-year-old Arnna Kathleen (born November 11th, 1958), and four-year-old Grant Ellis Beaumont (born July 12th, 1961) disappeared from Glenelg Beach near Adelaide, South Australia.
The children were seen with a tall, blond, thin-faced man with a sun-tanned complexion and a slightly athletic build. He was approximately in his mid-30s and wearing swimming trunks. Despite numerous searches, the children nor their companion were ever seen again.
As of 2018, an A$1 million reward was offered for information related to the cold case by the South Australian Government.
