Overview: CI investigates into two of the most infamous unsolved mysteries in Australian criminal history are examined in The Wanda Beach Murders and The Beaumont Children Mystery.In 1965, when Australian teenage culture was centred on sun, sand, and surf, the nation was shocked by the brutal bashing, rape and murder of two 15-year-old girls in the sand hills at Sydney's Wanda Beach. A massive police hunt failed to find the killer but now, more than 40 years later, there is growing evidence that he could be a known psychotic murderer. A year later, on an Australia Day outing to a beach in Adelaide, three small children, Jane, Arnna, and Grant Beaumont, disappeared suddenly and without a trace. Were they abducted by the man seen playing with them at the beach, or were they buried in an accident, as claimed by a world-famous clairvoyant who was flown to Adelaide from Europe by the media and concerned local citizens? Are they still alive?
