Calgary police are looking for help in identifying two people who may have information about a double homicide in 2008.

A man and woman, both 21, were shot while eating at a restaurant on Marlborough drive northeast.

Police say the shooting is linked to a long-standing conflict between two rival street gangs.

They released surveillance pictures Wednesday of two people caught on camera at a convenience store around the same time as the shooting.

Anyone with information is asked to contact Calgary Crime Stoppers.
