The second incident was a medical emergency on northbound I-94 at 83rd Street, that happened just 10 minutes after the first crash. The driver of a motorcycle was having a medical emergency and is in serious condition. 

About an hour and a half later, there was a four-vehicle accident on southbound I-94 at 87th Street. One adult suffered serious injuries and an infant suffered life-threatening injuries.

Around 4 a.m., there was a two-car crash on the southbound Dan Ryan at 73rd Street that caused one car to burst into flames. The driver of that car was pronounced dead at the scene. The other driver has non-life threatening injuries.
