A second person was charged in the fatal shooting of a retired firefighter early December during an attempted carjacking outside a Morgan Park popcorn shop.
Johnson, of Gary, Indiana, was arrested Wednesday afternoon by the FBI’s Violent Crimes Task Force in suburban Oak Forest, police said.
He was expected to appear in court later Friday to face a count each of first-degree murder, attempted vehicular hijacking, unlawful possession of an automatic weapon and unlawful possession of a weapon.
Earlier Thursday, a 15-year-old boy was charged as an unarmed accomplice in the shooting.
Chief of Detectives Brendan Deenihan said the suspects were part of a group responsible for a number of other crimes in the area.
Two other suspects haven’t been arrested, police said Thursday.
On Dec. 3, the carjackers allegedly followed Williams as he drove to Let’s Get Poppin’, at 11758 S. Western Ave., with the intent to carjack him, prosecutors said during the teen’s bail hearing Thursday.
In surveillance video of the shooting, two people with guns are seen approaching Williams as he walks towards his Jeep with a bag in his hand, authorities said.
Williams then retreats behind his car as a suspect with a gun rushes towards him, authorities said. William fires his own gun and a suspect falls to the ground before returning to the car and fleeing.
Williams was shot in the abdomen during the exchange of gunfire and died at Christ Medical Center in Oak Lawn, authorities said.
Williams was a Chicago Fire Department lieutenant who retired about two years ago, officials said. He was about to return to work as a civilian employee at the Office of Emergency Management and Communications.
A group of activists have put up a combined reward of $34,000 for information leading to any arrests in his killing.
It wasn’t immediately clear if someone claimed the reward.
