4-years-old murder unsolved MELBOURNE, Tuesday. — The Coroner, Mr H. E. McCallum, SM, today found at Shepparton that Abina Madill, 16, and Garry Heywood, 18, were murdered by a person or persons unknown in the early hours of February 11, 1966. Mr McCallum was told that the two had been found in a paddock at Murchison East, 21 miles from Shepparton. First Constable Peter Parkinson said that inquiries into the deaths were still being carried out and that 347 people had already been interviewed. Unfulfilled police hopes of solving the case were the reason for the four-year delay in holding the inquest.
