The first day of the trial over the killing of notorious Sydney businessman John Macris took place at an Athens court on 1 July with the two Bulgarian brothers accused of his killing insisting on their innocence.

Widow Victoria Karyda came face-to-face with the alleged hitmen, reportedly sitting just a few meters away from them in the court room.

“They will get what they deserve,” reads a statement of hers, regarding the accused, to Greek media ahead of the trial, reiterating “complete confidence in that the Greek judicial system will perform its task appropriately”.

Dubbed as an underworld figure by Australian media, John Macris was murdered outside his Athens home, in late October 2018.

A Bulgarian national has been singled out by authorities for allegedly carrying out the execution-style killing following CCTV footage showing a man resembling him firing the fatal shots directed to Mr Makris.

But the 32-year-old man denies having any motive to kill Mr Makris saying he didn’t know him.

The brother of the accused, 31, is also facing charges for having allegedly driven the getaway car during the operation.

The case was adjourned and set to resume on Thursday 9 July.
