Robert Johnson, 52, of Chicago was killed on April 7, 2020, during an attempted carjacking in the 4700 block of West Fulton Street. Johnson was standing beside his longtime girlfriend’s SUV after walking her to her car when a white sedan with four people inside pulled up. Three people exited the sedan and attempted to take the SUV; an exchange of gunfire followed after one of the men, identified as Jimmy Walker, pointed a gun at Johnson. Johnson was shot in the chest and later died of his wounds.

Nearly two years later prosecutors charged three people in connection with the killing. Jimmy Walker, who was 19 at the time of the attack, was charged with first-degree murder. Malik Boyd, 17 at the time, and a 15-year-old were charged with murder during a felony; a fourth person in the sedan has not been identified. Charges also included attempted vehicular hijacking and attempted robbery with a firearm. Prosecutors did not explain the nearly two-year gap before charges were filed, and the investigation remains open.

If anyone has information about the incident or the unidentified fourth occupant of the white sedan, please share what is known.
