Both victims were bar patrons, according to police, but they aren't sure if they were targets or if this was a random crime.
"We don't know at this time if they were intended victims or they were caught in the crossfire," according to Chief Inspector Scott Small.
Investigators say they are following a trail of blood leading away from the bar, and aren't sure if there is a third victim or if the suspect was injured.
Police are interviewing witnesses who were inside the bar at the time. The shooter is described as a male in his 30s, heavy-set with a beard, and wearing a striped shirt.
