Now, there's nothing in the video proving the man fired the first shot, but about 5 seconds later he is seen raising his weapon and seemingly firing it. It's unclear where Takeoff or Quavo were in relation to him at that moment.
Houston PD tells us they have seen this video, and have deemed the man a person of interest. They have not identified him yet.
As we reported, Takeoff was standing a few feet behind Quavo early Tuesday morning outside the Houston bowling alley when things got heated.
After the gunfire -- at least 10 shots were fired -- Takeoff had been hit in the head, and was pronounced dead on the scene.
Two other people suffered non-life-threatening injuries.
