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. ---  Researched and written by the Anonymous Host Greatly assisted in research and co-written by Anna Priestland For all credits and sources please visit casefilepodcast.com/case-46-frankston-tynong-north-serial-killer
