Chicago cops want to know if NBA nomad Antoine Walker's b-day had anything to do with a fatal shooting yesterday morning.

A man was killed around the corner from the club where Walker had his birthday party Sunday night and the popo are investigating whether the shooting stemmed from a gang fight, possibly inside the club. The Chicago Sun-Times reports 'Toine's party was at club Excalibur.

Walker himself hasn't been connected to the shooting as yet.
