A gunfire exchange on a Detroit freeway Tuesday forced I-96 to close down, less than 24 hours after a shootout on the same interstate left three people dead. 

An SUV was driving southbound on the freeway when another vehicle pulled up alongside it and started shooting. The driver of the SUV was struck and a passenger, who left the scene, may have been struck as well.
