Louis Walker, a 28-year-old African American man, was shot on April 7, 2015, while sitting in the driver’s seat of his car on the 4700 block of North Broadway in the Uptown neighborhood of Chicago. An assailant in another vehicle opened fire; Walker was critically wounded, taken to hospital, and died of his injuries on May 7, 2015. The Cook County medical examiner ruled the death a homicide.

Police described the attack as a targeted drive-by shooting. Detectives reviewed surveillance footage, conducted numerous interviews, and followed up on tips, but initially had few leads and no arrests were made. Progress was hindered by a lack of eyewitnesses willing to come forward, and investigators continued to appeal to the public for information.

Did anyone in Uptown at the time see the shooting or notice suspicious vehicles in the area around April 7, 2015?
