The man accused of ordering a hit on a Sydney teenager had a series of ominous tattoos alluding to revenge inked on his body following the 15-year-old's murder.
Abdul Abu-Mahmoud is on trial in the NSW Supreme Court over the death of the 15-year-old who was gunned down as he slept inside his family home in Glenfield on Good Friday in 2017.
Another man, who can only be identified as CC, has pleaded guilty to being the gunman and is due to face court on Friday.
Abu-Mahmoud, 35, has denied ordering or financing the execution-style killing and has pleaded not guilty to a string of charges including murder.
Prosecutors allege Abu-Mahmoud coordinated the hit as revenge after his nephew Adam Abu-Mahmoud was stabbed to death in a Panania street brawl in July 2016.
Joshua Dillon was charged over Adam Abu-Mahmoud's death, but was ultimately found not guilty by a jury in October last year.
Abu-Mahmoud is accused of ordering that Dillon's brother be killed as retaliation for the death of his 18-year-old nephew.
According to the agreed statement of facts, Abu-Mahmoud acquired several tattoos which alluded to revenge following the teenager's murder.
Among them, he had "my family is not to be f***** with" and "if we do nothing than (sic) we are nothing" written on his torso.
Another on his left leg read "Revenge is a dish best served cold".
Prior to the teenager's killing, he also had "eye for an eye, tooth for a tooth and blood for blood" inked on his left arm in Arabic text.
During his opening address earlier this week, Abu-Mahmoud's lawyers attempted to point the finger at Bassam Hamzy, the founder of notorious street gang Brothers For Life.
Abu-Mahmoud's lawyer Ertunc Ozen SC told the court that the shooter was a Brothers For Life member and that Hamzy directed all aspects of the gang's operations including killings.
The teenager was shot once in the head after a hooded gunman kicked in the front door of his family's home in Glenfield on April 14, 2017.
His mother this week gave evidence that the killer threatened her with a gun and ordered her back into her bedroom before she heard the shot which killed her son.
CC was released on parole on March 26, just 19 days before he shot the teenager.
The trial before Justice Ian Harrison will continue next week.
