On Labor Day, four people were killed in a train crash in the Chicago area, police said

Four people were killed on a commuter train in the Chicago area on Labor Day, police said.

Police were dispatched to a train station in Forest Park, a village 10 miles west of Chicago, around 5:30 a.m. after receiving a call that three people had been shot. Three people were pronounced dead at the scene, while one was taken to the hospital and died there, Forest Park police said.

The train was moving on the system's Blue Line, and the shooting occurred between two cars, police said.

The suspect initially fled the scene but was later located through surveillance video from the Chicago Transit Authority. Police have now taken the person into custody and seized a firearm.

“This is an isolated incident, this kind of thing can happen anywhere,” said Forest Park Deputy Police Chief Christopher Chin. “Obviously there is a little more cause for concern because it is a public transit system, but you have to understand that safety measures have been put in place, not only by our local police departments that travel along the line, but also by the CTA.”

Forest Park Mayor Rory Hoskins said the village's fire and police departments are frequently called to the station. He added that village officials have asked state leaders to provide Forest Park with more funding for mental health and opioid addiction.

“As far as our leaders in Springfield [Illinois] If someone is considering restructuring CTA public transit, we would ask them to consider investing additional resources in terms of security, public safety, police personnel, etc. to support a small community like Forest Park that has to respond to two major rail lines that terminate in Forest Park,” he said.

Information about the victims has not yet been released.

Forest Park Police, Chicago Police, West Suburban Major Crimes Task Force and Chicago Transit Authority are working together to investigate the shooting.
