Three people were pronounced dead at the Forest Park station, an above-ground stop on the Chicago Transit Authority’s Blue Line. The fourth victim died at a hospital.
The suspect got away but was subsequently arrested on a train on a different route, Forest Park police said.

He called the shooting “shocking” and “horrible.”
“This heinous and egregious act of violence should never have occurred, nonetheless on a public transit train,” the Chicago Transit Authority, known as CTA, said.
CTA said security camera video “proved to be vital” in helping investigators.

Forest Park Mayor Rory Hoskins said his community, population 14,000, is the only Chicago suburb in Cook County where two major train lines end.
“It’s a horrible tragedy that four people are dead on Labor Day weekend,” Hoskins said.
“Our police department and our fire department respond to this location probably more than any other location in our jurisdiction.”
