The episode details the 1977 Easey Street murders in Melbourne, Australia, where two women, Suzanne Armstrong and Susan Bartlett, were brutally killed. Despite a lengthy and complex investigation involving numerous suspects and a substantial reward, the case remained unsolved for nearly 50 years. A 65-year-old man, Perikilis "Perry" Kouroumblis, was recently arrested in Italy in connection with the murders and is awaiting extradition to Australia. His arrest represents a significant breakthrough in the investigation, which has garnered considerable media attention over the decades, including books and podcasts. Kouroumblis was a student at the same school where one of the victims taught.
