Rapper Takeoff died from gunshot wounds to the head and torso following a shooting outside a private party at a downtown Houston bowling alley, authorities announced Wednesday.

The announcement — following an autopsy by the Harris County Institute of Forensic Sciences in Houston — comes as police are still seeking the public’s help in tracking down the person or persons responsible for the rapper’s death Tuesday.

Takeoff’s primary cause of death was listed as “penetrating gunshot wounds of head and torso into arm” and his manner of death was called homicide.

Takeoff, whose off-stage name was Kirsnick Khari Ball, formed one-third of the Grammy Award-nominated rap trio Migos with uncle Quavo and cousin Offset from suburban Atlanta.

The 28-year-old rapper was killed around 2:30 a.m. Tuesday when gunfire erupted outside of 810 Billiards & Bowling following a private party.
