In the 18 month period between May 1980 and October 1981, six women went missing from the Frankston and Tynong North areas in Melbourne’s south-east. The victims – Bertha Miller, Catherine Headland, Ann-Marie Sargent, Narumol Stephenson, Allison Rooke and Joy Summers – were later found murdered and dumped in remote scrubland. Obvious efforts had been made by the offender to prevent the victims from being identified.
