Ten years after Jason De Ieso’s death, a jury has convicted seven men guilty of his murder, however it was unable to convict an eighth defendant. Seven individuals connected to the Hells Angels were found guilty by the jury of shooting and killing Jason De Ieso in 2012 – but they could not agree on one count.

The following men were found guilty of murder: Daniel Mark Jalleh, 34, of Clovelly Park; Ross William Montgomery, 38, of Andrews Farm; Kyle Lloyd Pryde, 35, of Adelaide; brothers Husain Alzuain, 36, of Goodwood; Mohamed Alzuain, 32, of Mile End; and Musa Ali Alzuain, 30, of St Morris. Greek-Australian Nicholas Sianis, 36, of Beverley, is also among those found guilty.

Regarding Walkley Heights resident Seywan Moradi, 36, the jury was unable to reach a decision.

Following six days of nonstop deliberations that started on Wednesday afternoon, the Supreme Court jury foreman delivered the verdicts, which mean that Husain Alzuain, Mohamed Alzuain, Musa Ali Alzuain, Daniel Mark Jalleh, Ross William Montgomery, Kyle Lloyd Pryde, and Nicholas Sianis, will serve mandatory life sentences.

Former Olympic boxing hopeful Musa Alzuain was identified as the one who pulled the trigger – when he was just 19 years old. The group of nine men – who belonged to the Hells Angels motorcycle gang – were involved in a growing dispute with their competitors, the Finks.

The day before the attack, the home of the Alzuain brothers was firebombed, marking the culmination of events that followed. After receiving information that their intended victim, a member of the Finks, was at the Pooraka workshop, the men assassinated De Ieso instead of the target, who they missed by a few minutes.

Given the degree of disturbance the case caused to their lives, Justice Martin granted the jurors exemption from jury duty in the future. Upon the trial’s conclusion, Justice Martin addressed the jurors and told them “you did your job well and be satisfied in that knowledge that you’ve done the job well and served your community.”
