A 15-year-old boy from Crystal Lake has been identified as one of two victims killed after their car struck a deer and another car slammed into the rear of them on Interstate 90 near Hoffman Estates Monday morning.

The Illinois State Police said that District 15 troopers responded to a call of a two-vehicle crash on westbound I-90 at mile marker 59.25 in Cook County around 1:45 a.m. Monday.
