The crash happened Tuesday in the 7000-block of East 117th Avenue just after 4:30 p.m.
Witnesses told police a Subaru SUV traveling east was tailgating a Jeep. It tried to pass the Jeep, and crossed the center line into oncoming traffic, where it collided head-on with a Kia driving west.
The Kia's driver, 19-year-old Grace Norris, was pronounced dead at the scene. There were also two 13-year-old passengers from Lowell in the car. One was taken to a Chicago hospital for treatment by helicopter, while the other was eventually transported by ambulance, the Lake County Sheriff's Department said.
The driver of the Subaru is a 44-year-old woman from Crown Point. No further information was available and there is no word on any possible charges against the driver.
