A Greek Australian dual national is a step closer to being extradited from Rome to Australia over the horrific cold-case killings of two Melbourne women. Perry Kouroumblis was arrested at Rome’s Leonardo da Vinci airport in September, decades after the murders of Suzanne Armstrong, 28, and Susan Bartlett, 27, in January 1977. The friends were found dead with multiple stab wounds in their home on Easey Street in Collingwood. Bartlett’s 16-month-old son, Gregory, was found unharmed in his cot.
