The victims included a 3-month-old girl, a 23-year-old female passenger and a 22-year-old male driver, Illinois State Police said in a statement.

The vehicle then struck a tree and started on fire, state police said. Illinois Route 50 was closed for an investigation until 2:20 a.m.
The Will County coroner’s office has not released the victims’ names.
