Police hope a re-enactment will help identify a shooter responsible for killing a B.C. gangster outside a Calgary night club.

David Tajali, 33, of Vancouver was killed in a hail of bullets September 6th, 2009 when someone opened fire on his BMW in a parking lot behind Boulevard Nightclub on 19th avenue S.W.

Tajali's brother, Niki was also shot at the same location. He was taken to hospital in a dark-coloured SUV and survived.

However, police say he is not cooperating with the investigation.

The brothers are not strangers to violence. Both had survived previous attempts on their lives.

Police have composite drawings of two suspects. They believe one was the shooter, the other a lookout.

Police have talked to a number of people since the shooting, but they're still trying to track down two key witnesses.

Two young women were seen talking to the man identified as the lookout prior to the shooting.

"We know there are people in the community who have information in regards to this incident. For a number of reasons, they have not come forward whether it's out of fear or they feel we already have the information, or that they feel their information is insignificant," says Staff Sargeant Doug Andrus with the Homicide Unit.

Anyone with information about this homicide can call Crimestoppers at 1-800-222-TIPS.
