The early Monday morning gunfire near the landmark Rock 'n' Roll McDonald's left one man dead and another in critical condition, the Chicago Sun-Times reported Tuesday. Curtis Ellis, 25, died at Stroger hospital, authorities said, while the second victim, an unidentified 30-year-old, was listed in critical condition.
Walker's birthday party was held at Excalibur, a nightclub about a block away, said sources. Police are investigating the possibility of whether there may have been a fight and whether the shooting stemmed from a gang dispute.
Walker, who was recently traded from the Minnesota Timberwolves to the Memphis Grizzlies, was the victim of a home invasion last year.
