However, less than three hours later, Duane Davis was gunned down in the living room of his home.Police hope the people in the nightclub pictures can help pinpoint a killer, or killers."Don't know if they were in some kind of general conversation with them," said Joyce. "Hopefully, they can ID the folks in the parking lot. That's what we are trying to find out, so we can identify the person our victim and brother were engaged in an altercation in the parking lot prior to his death."Police say they have talked with one of the people in the surveillance pictures, but investigators have not said what if any information that person may have revealed.Anyone with information is asked to contact Detective J.
