Sylvester Adams, 53, reportedly shot a 37-year-old man after an altercation at the 95th Street CTA Red Line station in the South Side of the city that escalated early Saturday morning. Chicago police said the two men were arguing around 2:13 a.m., but when the victim started to walk away, it was then that Adams shot him, hitting the man three times. He was shot in the lower abdomen, back and left leg. The man who was shot was taken to the University of Chicago Medical Center in critical condition. The Chicago Transit Authority confirmed in a statement Saturday that Adams was a CTA employee working as a customer assistant. The CTA said it was seeking the dismissal of Adams, who had broken various rules in the workplace, including possession of a firearm. “The CTA continues to work closely with the Chicago Police Department as it investigates last night’s incident and the circumstances surrounding it,” the CTA said. “The behavior of this one employee does not at all reflect the thousands of hardworking, dedicated men and women who take pride in their work and perform their duties responsibly every day.” SEE ALSO Chicago crime: Man shot and killed during car theft attempt at Belmont Central, police say Police arrested Adams, who lives in Lynwood, and found a gun at the scene.
