He fell at about 4:55 p.m. from a balcony between two columns on the west side of the stadium, between gates 19 and 21, approximately level with the 50 yard line, police said.
The flat roof Haverty landed on is about 35 feet below the balcony.
In order for this to have happened, Stuart would have had to have jumped or fallen over a three-foot high railing on the balcony, then fallen off a ledge that appeared to be at least two feet wide before plunging down.
Rumors quickly spread at the stadium that the man had run and jumped off the balcony, but police believe the death was an accident.
The room Haverty landed on is about 15 feet high, and the fire department needed a ladder with a basket to get the man down.
The man was pronounced dead at Northwestern Memorial Hospital.
In happier news, the Bears won the game in impressive fashion over a very good Philadelphia Eagles team led by Michael Vick. So there is always a silver lining.
