CHICAGO (STMW) – A woman who was killed when she fell off her bicycle and run over by a dump truck in a “tragic accident” Downtown late Friday has been identified.

Jacqueline Marie Michon, 25, of an unidentified address, was dead on the scene, according to the Cook County Medical Examiner’s office.

An autopsy Saturday determined Michon died of multiple injuries from a truck striking a bicyclist, according to the medical examiner’s office. Her death was ruled an accident.

The incident unfolded about 10:45 p.m. when the victim rode between a dump truck and a four-door vehicle stopped in the northbound lanes of North Wabash Avenue at East Wacker Drive, police News Affairs Officer John Mirabelli said.

Witnesses told police the woman lost her balance and fell under the rear axel of the truck, which proceeded northbound when the light turned green, Mirabelli said.

A civilian alerted the truck driver that he had run over a bicyclist, and the truck driver stopped and remained on the scene, Mirabelli said.

The incident is not considered a hit-and-run, and the police Major Accident Investigation Unit is conducting an on-going investigation to determine if the driver will be ticketed or charged.

“It’s a tragic accident,” Mirabelli said. “It appears from witnesses … that the bicyclist had lost her footing and slipped under the wheels.”

Belmont Area detectives are also investigating.
