Authorities in Chicago say a 24-year man suspected of killing a man who protected a woman in an earlier attack was being held without bond pending a preliminary court appearance.

Terrell Cobbs, was charged Thursday with first-degree murder in the fatal shooting of 31-year-old Gregory Hampton.

Police say Cobbs fought with a woman on the street on Tuesday afternoon and was kicking her in the head when Hampton intervened and chased him off. Cobbs allegedly returned later and shot Hampton fatally.

Police located Cobbs at a West Side dwelling a short time later. Officers say that when he was being questioned, Cobbs initially told them his name was "Ernie Banks" -- apparently referring to the Chicago Cubs Hall of Famer -- but another resident identified him as the wanted man.
