Freshman psychology major Summer Adi died Wednesday night when the car she was riding in spun out of control on Interstate 88, near Downers Grove, said David Furjanic, master sergeant of the Illinois State Police.
Adi and the driver were taken to a local hospital where Adi later succumbed to an infection.
Furjanic said the car jumped the median, was airborne for a short time and flipped onto its roof after the driver lost control.
Furjanic said that preliminary investigation does indicate that the car might have been travelling at a high rate of speed. Eyewitness accounts support that information.
