CHICAGO (CBS) — Questions swirled about a woman found dead at O'Hare International Airport Thursday in a non-public area of the airport used for baggage distribution. 

The woman was found in Terminal 5—the international terminal—and died at the scene, according to the Chicago Fire Department. She was identified as a 57-year-old woman from North Carolina, according to the Cook County Medical Examiner's Office. Her death was ruled a suicide.

Sources said the woman was in an area at Terminal 5 that the public cannot access—but her presence there would not be considered a security breach because it did not take place in a high-security area.

How she got there still wasn't known as of Thursday.

Fire Department personnel at O'Hare found her unresponsive. They say they were called at 7:45 a.m.

Sources said when airport video was reviewed, the woman was seen walking in the area as early as 2:27 a.m.  

She was pronounced dead at the scene.

CBS News Chicago has checked with the Occupational Safety and Health Administration, or OSHA, which said it is not investigating because the woman was not an airport employee.
