I may have missed it, but do we know where and when the 3 men were spotted on video? If they were in the same area around the same time as the shooting, that could feed into some of the theories, but if they were in a different area at a different time, it's obviously less likely. "Two white males, one black male" might seem like it "has to be" referring to the same group caught on camera, though there is no mention of clothing, age, height, or really any other descriptives that would really help to confirm.
