Jason De Ieso murder trial: Musa Alzuain fired fatal shot in bikie feud, prosecutors allege

The only non-bikie gang member among eight men standing trial charged with the murder of Jason De Ieso fired the fatal shot, a Supreme Court jury has been told.

The youngest of the three Alzuain brothers – Musa Alzuain – allegedly fired the fatal shot that killed innocent man Jason De Ieso in the middle of a bikie war, a court has heard.

Prosecutor Jim Pearce KC is continuing his opening remarks in a murder trial relating to the death of Mr De Ieso, who was fatally gunned down inside his Pooraka workshop on November 21, 2012 amid an escalating bikie war between the Hells Angels and the Finks.

He told the jury it was alleged Musa Alzuain – who is the only non-gang member among eight men linked to the Hells Angels who are standing trial in the Supreme Court charged with Mr De Ieso’s murder – fired the lethal bullet.

“The case against Musa Alzuain is that he is the man responsible for firing the fatal shot,” Mr Pearce said.

He said Musa Alzuain – the only non-Hells Angels member among the accused – was wearing a blue hooded jumper on the day and carrying a sawn-off shot gun. Mr Pearce said he was seen getting into the driver’s seat of one of the cars and his DNA was later found on the seatbelt, steering wheel, gear stick and handbrake of the car.

“There’s only one weapon seen on the CCTV footage that could fit the bill for the weapon used to fire the fatal round,” he said.

He said of the nine men who approached the workshop disguised in hooded jumpers, five who were carrying guns and three of those were fired. Two of those guns were .22 pistols and did not fire the fatal shot.

Mr Pearce told the jury that one of the other guns used in the shooting was seized by police two days later in an initially “seemingly unrelated” incident.

He said Musa Alzuain had given the gun to another man, who then left it in his car when he parked near Light St in the CBD and attempted to get into a nightclub – but was rejected.

Police then converged on the man’s car and found the gun.

The jury heard ballistics testing later revealed that markings on a spent bullet found at the scene, matched one found in a pool of blood near Mr De Ieso’s head.

Mr Pearce said the man rejected from the nightclub told police Musa Alzuain had given him the gun, and told him he would likely just cop a fine if police came across it.

He said Musa Alzuain had told the man: “hold on to it because people may come in here and do what we did”.

Mr Pearce told the jury Musa Alzuain and his brother, another of the murder-accused, Mohamed Alzuain, visited the man a couple of days after police found the gun.

“The first thing they asked him was whether he talked (to police),” Mr Pearce said.

He said the man had asked if the weapon was used in Mr De Ieso’s murder.

“Musa Alzuain responded to the effect that ‘it probably wasn’t used on the guy but that he thought somebody might have fired a shot in the air and maybe something was left at the place’,” Mr Pearce said.

Along with Musa Alzuain, 30, of St Morris and his brother Mohamed Alzuain, 31, of Mile End, six other men – Husain Alzuain 35, of Goodwood, Daniel Mark Jalleh, 34, of Clovelly Park, Ross William Montgomery, 38, of Andrews Farm, Seywan Moradi, 36, of Walkley Heights, Kyle Lloyd Pryde, 34, of Adelaide and Nicholas Sianis, 36, of Beverley – have each pleaded not guilty to a charge of murder.

Mr Pearce said that Husain Alzuain – the eldest of the three brothers – was the only fully patched Hells Angels member at the time of the shooting and, wearing a red hoodie and black pants with a white stripe, led the group towards the workshop. He said that except for Musa Alzuain, the remaining accused men were considered Hells Angels “prospects” at the time before each becoming full members of the gang.

He said it was alleged Husain Alzuain was carrying a gun, but that it was likely the gun he was holding did not fire. Mr Pearce said Mohamed Alzuain, who was wearing a grey hooded jumper, was not carrying a gun.

He said the two men who carried the other guns which were fired were Mr Pryde, who was dressed in a red jumper, white cap and black trackpants, and Mr Jalleh who wore a white gloves, sunnies and a black hoodie that blew off his head as the group fled to reveal a distinctive scar and tattoo at the back of his head and neck.

The jury heard Mr Sianis wore a grey hooded jumper and dark cap and also drew a firearm.

He said Mr Montgomery, who wore a black hoodie with a white logo and scarf across his face, carried a metal bar but not a gun, while red-hoddie wearing Mr Moradi did not have a weapon and put his hands to his head when the shots were fired, before turning and running.

During the first day of his opening remarks on Wednesday, Mr Pearce said Mr De Ieso had just exited the office at his Langford St, Pooraka workshop, when nine disguised men approached, some of whom levelled guns and fired.

He was shot several times in the head at point blank range.

Mr Pearce had told the jury Mr De Ieso was not the intended target of the shooting, but that the men were instead after a member of the Finks who frequented the workshop, Charles Bonnici.

The trial, before Auxiliary Justice Brian Martin a jury of 15, is continuing.
