A terrible tragedy occurred at Chicago’s O’Hare International Airport. According to CNN, firefighters were called to the airport early this morning. There was a report that someone was trapped in the machinery used to transport and sort luggage. Larry Langford, a spokesman for the Chicago Fire Department, said they found a 57-year-old woman caught in the luggage compartment’s conveyor belt system.

Langford further stated that the baggage area is not open to the public. It is currently unclear how the woman got there. Scott Allen, a spokesman for the U.S. Department of Labor, stated that an “Occupational Safety and Health Administration official visited the scene and learned that the woman was not an airport employee.”

The firefighters then turned the crime scene over to the police. The Chicago Police Department’s communications department said in an email that the woman was found unconscious. Unfortunately, she was pronounced dead at the scene. The investigation is ongoing. The police communications department initially said the woman was discovered five hours before firefighters and paramedics arrived.

However, it was later clarified that surveillance footage showed the woman walking through the luggage compartment at the time. Her official death was not confirmed until five hours later, at which point the emergency call was made.
