A 19-year-old man has been charged in the 2011 triple murder outside of a bakery on the city's south side.
Aaron Barnes was arrested and charged on Friday with three counts of first-degree murder, according to police.
Prosecutors accuse him of shooting and killing 21-year-old Chanda Thompson, her boyfriend Shawn Russell and their friend Cortez Champion, according to the Chicago Tribune.
Barnes reportedly shot Thompson, Russell and Champion on Nov. 5 while they sat in a car outside of "A Piece of Cake Bakery" in the Chatham neighborhood.
Prosecutors had first charged 17-year-old Nicko Grayson in the murders, but dropped the charges after new evidence and witnesses came forward, police said.
The Tribune reports Barnes was convicted in 2011 for unlawful use of body armor and possessing a gun without a Firearm Owner's Identification Card.
