Police investigating the shooting death of Joseph Douglas Cameron in a Dartmouth neighbourhood are looking for witnesses who may have seen a dark blue 2012 Kia Rondo in the area around the time he was gunned down.

Cameron, 20, was killed on March 29. A report of shots fired came in at about 5:20 a.m. and police found Cameron's body on the sidewalk in the area of Spring Avenue and Mount Edward Road.

Police say they'd like to speak with anyone who may have seen a dark blue Kia Rondo in that area between midnight and 5:20 a.m.

A Halifax Regional Police spokeswoman says she does not know why investigators are seeking information about the vehicle.
