A 42-year-old northwest suburban man was killed in a single-car crash on Interstate 57 early Saturday on the Far South Side.
About 4:30 a.m., Frank J. Tomaszewski Jr. was driving a vehicle that veered into the wall of the southbound lanes of I-57 near 107th Street, according to Illinois State Police and the Cook County medical examiner’s office.
He was taken to MetroSouth Medical Center in Blue Island, where he was pronounced dead at 5:36 a.m., authorities said.
An autopsy Sunday found he died of blunt force injuries to the torso, with cirrhosis listed as a secondary cause. His death was ruled an accident.
Tomaszewski lived in the 1400 block of Heather Lane in Des Plaines, authorities said.
No one else was injured. The cause of the crash is under investigation.
