Percy's father, a sailing enthusiast, had been a New South Wales railway electrician before deciding to take a job with the State Electricity Commission in Victoria, and moving to Chelsea in 1954, then to Warrnambool in 1957, and to Mount Beauty, near Bright, in 1961.
[2] Percy began to attract the attention of authorities in late 1964, when he started stealing and wearing female underwear and dresses and mutilating dolls with knives and razor blades.
[3] In 1965, the family relocated to Khancoban in New South Wales (their sixth move in twelve years) where Percy began writing down bizarre and violent sexual fantasies.
[2] Percy was arrested at Cerberus, adjacent to Crib Point on the Mornington Peninsula south of Melbourne, for the murder of 12-year-old Yvonne Tuohy at Ski Beach, near Warneet on Westernport Bay, on 27 July 1969.
[5] When questioned, Percy denied involvement, but eventually led police to Tuohy's mutilated body in a paddock on Fisheries Road at Devon Meadows, some 8 kilometres (5 mi) from the abduction scene.
