CHATHAM — Detectives are asking neighbors to help identify two people suspected in the fatal shooting of a 29-year-old man a CTA train car in what the city’s top cop called a “senseless act of gun violence.” 

The shooting happened around 2 a.m. Saturday on the Red Line’s 79th and Dan Ryan stop, Supt. David Brown said at a press conference Saturday.

Diuntel Moon, 29, was on a train car when someone shot him multiple times in his chest and abdomen, Brown said. He was pronounced dead at a hospital. 

Detectives shared surveillance video footage from the train car Saturday that shows two men detectives believe shot Moon. 

In the video, two men in a black jacket and a red hoodie can be seen talking to someone off-screen. The two stand up and the man in black can be seen with his right hand inside his jacket. After a “brief conversation,” one of the men used a gun to shoot Moon, detectives said. 

Detectives are asking neighbors with information to call at 312-747-8271 or submit an anonymous tip here.

Following that shooting, Brown said cops on desk duty might be assigned to guard CTA trains, stations and buses. Police from narcotics and gang units have also been enlisted to boost CTA patrols, Brown said.

CTA officials hired four private security firms and dozens of unarmed guards to monitor stations in April after riders noted a rise in rowdy behaviors like smoking and urinating. These behaviors spiked as ridership dwindled due to the pandemic.

Dorval Carter, CTA president, said they would reinstate K-9 security teams within the next week. 

“Perception of safety is as important as the actual safety,” Brown said Monday. “If I don’t see officers then I don’t feel safer. But if I see officers, maybe I feel a little safer, perception-wise.”

The Chatham shooting joins a list of recent violent attacks on CTA trains and buses. 

In July, four people were stabbed in an attempted robbery on a Red Line train in Lincoln Park, and in June, a 17-year-old boy was shot and killed on a bus in West Garfield Park. 

“Violent crime is up, and that’s why we’re adding more and more resources to the CTA,” Brown said Saturday.
