A decision on if Easey St murders suspect Perry Kouroumblis will be extradited from Italy could be made as early as next week.

According to the Herald Sun, homicide squad detectives are on standby to travel to Rome after a brief of evidence was sent to Italian authorities.

Kouroumblis is the suspect for the murders of Suzanne Armstrong and Susan Bartlett in Collingwood, Melbourne, in 1977.

A brief was sent to federal Attorney-General Mark Dreyfus before being conveyed to Rome well ahead of the 45-day deadline, which began when Kouroumblis was arrested at an airport two months ago.

Despite Kouroumblis signalling he is prepared to be extradited, the file has been forwarded.

It’s been said police were well advanced in their brief preparation even before his arrest, which happened when he flew into Rome on September 19 from Greece.

He had been living in Greece since 2017, but extraditing from there would have been far more challenging because of his dual Greek-Australian citizenship.

It is believed homicide squad investigators are ready to travel to Rome at short notice, with Kouroumblis’ stated intention to return set to make things much easier.

A previous brief over what happened to the victims at their Collingwood home was prepared for an inquest, which was held months after the attacks.

Kouroumblis was 17 when Bartlett and Armstrong were murdered and was found with a knife in the boot of his car, days after the killings.

He told police he had found it on railway tracks not far from the scene.

In 2017 he left Australia after being asked to provide a DNA sample to cold case homicide investigators looking into the notorious crime.

His family have since denied he left Australia to flee the police investigation while he has always maintained he is innocent.
