HOUSTON (AP) — Authorities are searching for a man accused of shooting a teenager during what they say was a road rage incident that happened as a family was driving home following a Houston Astros game.

Houston police say the 17-year-old is on life support at a hospital following the Tuesday evening shooting.

Police say the teenager and his family were headed home from the game when his father exchanged hand gestures with the driver of a white Buick sedan.

Investigators allege the Buick’s driver followed the family for several miles before firing several shots at their truck.

The teenager was shot in the head.

Houston Mayor Sylvester Turner is asking for the public’s help in finding the shooter.
