A Sydney handyman has been found guilty of giving a group of assassins the key to a man's apartment before his murder.
Kemel "Blackie" Barakat was executed in 2017 by a group of unknown people who'd unlocked and entered through the front door of his Mortlake unit.
On Monday, NSW Supreme Court Justice David Davies found Ahmed Jaghbir guilty of procuring, aiding and counselling the murderers.
He said Jaghbir was the only person who could have provided a key for duplication, or a duplicate key, to the killers before the March 10 murder.
The court had been told Mr Barakat's slaughter was in the broad context of a series of numerous retribution-style murders including Hamad Assad, a friend of Jaghbir.
The judge said Jaghbir had three possible motives, including suspicion over Mr Barakat's possible involvement in Mr Assad's death and Jaghbir being apparently ripped off of $265,000 by Mr Barakat's "crew".
"If there had been no possible motive, I accept that its absence would have weakened, although not destroyed, the circumstantial case which is ... otherwise very strong," Justice Davies said.
"I take into account that any of these three possible motives means that the accused's involvement is not without a possible rational explanation."
Jaghbir, who pleaded not guilty and reserved his right to silence, is due to be sentenced at a later date.
