Two homes and a car were also hit in the exchange. It happened shortly before 10 p.m. near Sherman Boulevard and W. Derby Place.

Police say a gun battle erupted between two vehicles. Responding officers found a bullet-riddled car on Derby Place with a man in the back seat suffering from multiple gunshot wounds, including one to the head. He was pronounced dead on the scene.

The driver of that vehicle, a 21-year-old man, was taken to St. Joseph's Hospital by a witness, and was later taken to Froedtert. He is in stable condition with gunshot wounds to his chest and arms and is reportedly not cooperating with police.

No other injuries were reported.
