CHICAGO (CBS) — Chicago Police are investigating whether road rage led to a Lake Shore Drive crash that left a woman dead and a man seriously injured early Saturday on the South Side.

Witnesses saw a small red Honda take off after a vehicle slammed into a pole about 2:15 a.m. in the northbound lanes of the drive near Oakwood Boulevard, police said.

The 24-year-old woman at the wheel was dead at the scene, police said. A 27-year-old man in the vehicle was taken to Northwestern Memorial Hospital in serious condition.

Police said they believe road rage caused the woman to crash into the pole, so no citations will be filed.

An autopsy Saturday found she suffered multiple blunt force injuries in the crash and her death was ruled an accident, the Cook County medical examiner’s office said. Her identity has not been released.

The police Major Accidents Investigation Unit is handling the case.
