On 6 June 1949, the body of two-year-old Clive Mangnoson was found in a sack in the Largs Bay sand hills, about up the coast from Somerton Park. Lying next to him was his unconscious father, Keith Waldemar Mangnoson. The father was taken to a hospital in a very weak condition, suffering from exposure; following a medical examination, he was transferred to a mental hospital. The Mangnosons had been missing for four days. The police believed that Clive had been dead for twenty-four hours when his body was found. The two were found by Neil McRae of Largs Bay, who claimed he had seen the location of the two in a dream the night before. The coroner could not determine the young Mangnoson's cause of death, although it was not believed to be natural causes. The contents of the boy's stomach were sent to a government analyst for further examination.
