HOUSTON (AP) Police said they have few leads in the fatal shooting of rapper Takeoff outside a private party at a downtown Houston bowling alley.

Takeoff, whose off-stage name was Kirsnick Khari Ball, formed one-third of the Grammy Award-nominated trio Migos with uncle Quavo and cousin Offset from suburban Atlanta. The 28-year-old rapper was killed early Tuesday when gunfire erupted and also wounded another man and a woman, according to police Chief Troy Finner.

Most of the 40 people who attended the party at 810 Billiards & Bowling fled when the gunshots rang out, Finner said. That left police asking people to come forward and give statements and videos to investigators on what they saw and heard, even if anonymously, Mayor Sylvester Turner said.

At least two people discharged firearms, according to Finner. The two others who were struck by gunfire had non-life-threatening wounds and went to hospitals in private vehicles, he said.
