The incident occurred last Saturday, June 20, when three teenagers went to a store on the South Side of Chicago to buy some candy and ended up having a brief encounter with 19-year-old Laroy Battle inside the store.
The three teens left the store and headed home together when police said Battle approached them and began shooting.
Jasean Francis, 17, was shot in the back, chest and left hand. Charles Riley, 16, was shot in the back and left leg. The third teenager, who was not identified, managed to escape the shooting. The injured teens were taken to the University of Chicago Hospital and then died from the wounds they sustained during the shooting.
Laroy Battle, who has a previous conviction for illegal use of weapons, was arrested after being identified by local residents thanks to a video recorded by a surveillance camera. He is charged with two counts of first-degree murder.
