Bulgarian brothers Yuliyanov J Raychev Serafim and Milen Raychev are due to hear the verdict of an Athens court tonight Australian time.

They are being tried for the 2018 killingof Sydney underworld figure John Macris, 46, outside his home in Voula, an upmarket suburb on the coast of Athens. The two brothers were arrested after police claimed they found clothes matching those in Serafim’s hotel room along with a receipt and evidence that he rented a Nissan Pulsar in his name, which was caught on CCTV footage six times before the murder.

He fled Greece the day after the 31 October, 2018, murder but returned in April 2019 when he was arrested.

The mother of the two men accused of following Macris for 19 days before executing him in cold blood told the Herald Sun they are “very good gentlemen”. She says they are innocent because “their eyes tell everything”. She offered her sympathies to Macris’ widow, former Playboy model Viktoria Karida.

“They have all families and kids. They never can do that kind of things, they have respect for the people,” said the mother of the two accused.

At a court hearing in July, Serafim said “I am nothing but innocent, I have nothing to do with Macris’ murder. I believe in Greek justice.”

Greek authorities have linked the hit to a Canadian branch of the notorious Outlaws motorcycle gang.

Serafim is believed to have links to Australian crime figures living in Canada.

Macris had two children with Ms Karida, Alexandra and Achilles. His children found out how their father died after watching the execution clip on Youtube after hearing their classmates talk about it at school.

Top Greek lawyer Alexandros Lykourezos is defending the Bulgarian brothers. He argued that professional hit men would not use their own names to rent a car to be used in the killing.
