Security vision released as police close in on men who shot Jason De Ieso in Adelaide workshop
South Australian police have released security vision of a group of men with suspected bikie links taking part in a fatal shooting in Adelaide's north.
The vision overlooks the workshop of Jason De Ieso, 33, who was shot dead in the Langford Street premises at Pooraka in November.
It shows nine men approaching the workshop. Several of them then fire handguns and a sawn-off shotgun into the entrance before the group runs off.
Assistant Commissioner Paul Dickson says police believe they are members or associates of the Hells Angels motorcycle gang.
Police believe the murder is linked to a dispute between the the Finks and the Hells Angels gangs.
Assistant Commissioner Dickson says police believe they know who the nine men are but need confirmation to prosecute those involved.
"We've got information which nominates who they are but obviously before we put people before the court we've got to get to a particular threshold and we're not quite there," he said.
"We just need that little bit more to actually put them before the courts."
Assistant Commissioner Dickson says police have spoken to each suspect but none will cooperate.
"These individuals have never seen this vision before so in that we believe that when they do see that vision that it may change their position in cooperating with the police," he said.
Police say five of the men were carrying firearms and one of the men has a large scar on the back of his head.
They say Mr De Ieso was an innocent bystander caught up in the conflict.
His family has released a statement appealing for information about his murder.
"A family man who loved life and gave his heart to all of who came into contact with him. I stress Jason had no links to bikies apart from the released statement by police," the statement said.
"He ran a custom paint and panel business in which his doors were open to all. Repairing and working with cars and bikes was his passion.
"He dedicated all his efforts to produce remarkable results.
"He also did work for some Finks bikie members and associates, which does not mean he was one or was an associate.
"An innocent person, who had no involvement in any incidents which were occurring between the Finks and Hells Angels members. A husband, son, brother to all. A father-to-be who will never know his child."Police have previously offered a $500,000 reward for information leading to an arrest in the case.
