Right before Takeoff was shot to death, his uncle Quavo was arguing with a group of men about basketball.

TMZ has video of what went down right before the murder of the Migos member.  

As you can see somebody, likely Quavo, yells "I don't get down like that!"

About ten shots follow.

Houston police described the event as a private party with about 40 people at a bowling alley.  They responded to a call at 2:34 AM and found single male deceased outside the venue's third-floor entrance.  Police haven't named any suspects.

J. Prince Jr. and some of his Mob Ties affiliates were at the scene of the crime.
