Thunder Bay Police Service Primary Response officers responded to a 911 call last night in the 200 block of Ambrose Street just before 10:30 p.m. A female victim with serious injuries was located. A second male victim from this shooting was then located a short time later in the parking lot of the Thunder Bay Casino.
