The shootings of a pair of men in downtown Chicago may have resulted from a fight in a club where a party for Antoine Walker was taking place, according to The Post Chronicle.

The late Sunday night gunfire near Rock 'n' Roll McDonald's left one man dead and another in critical condition, the Chicago Sun-Times reported Tuesday.

Walker's birthday party was held at Excalibur, a nightclub about a block away.
