FOREST PARK, Ill — A man suspected of killing four people aboard a Chicago-area transit train shot them at close range while they were asleep, officials said Tuesday.
The shooting took place before 5:30 a.m. Monday aboard the Chicago area's L system, on a Blue Line train that was moving near where the line ends in Forest Park, a suburb about 10 miles (16 kilometers) west of downtown Chicago. A suspect was later arrested on another Chicago Transit Authority L line, according to police. Authorities charged the 30-year-old man with first-degree murder on Tuesday.
Forest Park Mayor Rory Hoskins said the victims likely didn't even see the shooter.
"They were shot execution-style as they slept," Hoskins told The Associated Press.
Three men and one woman were killed, according to the Cook County medical examiner's office. Forest Park police said all four were adults, but officials did not yet have exact ages yet for all of them.
Police said a preliminary investigation shows the victims were on two different cars as the Blue Line train was headed toward Forest Park. The Blue Line runs 24 hours and stretches from that suburb through downtown Chicago to O'Hare International Airport. It runs both below and above ground.
The suspected shooter fled. But police were able to find the man thanks to video footage from the train, Hoskins said.
Authorities identified him as Rhanni S. Davis of Chicago. Public records did not have a listed phone number for Davis. A message sent Tuesday to a listed email was not immediately returned. Forest Park police and the Cook County state's attorney's office did not immediately respond to messages about Davis' legal representation. The Cook County public defender's office said it wasn't representing him.
CTA officials said they were assisting in the investigation and that security footage "proved to be vital."
"Although this matter remains under investigation, all current information points this being an isolated incident," CTA President Dorval Carter Jr. said in a statement.
Forest Park police are used to calls to the busy transit stops there, Hoskins said. The CTA's Green Line also ends in Forest Park and runs nearly 24 hours a day.
Over the years, nonprofit organizations have also used the transportation hubs for outreach and providing medical care and other services to homeless people who seek refuge aboard the trains, particularly in winter.
But the mass shooting in the community of 14,000 people has sparked new fears. Hoskins, whose position as mayor is part-time, said he couldn't recall a homicide being reported in Forest Park in years.
His teenage son takes the L to school and he watched a little closer than usual at Tuesday morning's drop-off.
"People are rattled," he said. "We want to make them feel safe."
