CLEVELAND, Ohio -- Blueprints for Jacobs Field -- renamed Progressive Field in 2008 -- show a room with two garbage chutes in the northeast corner that drop straight down for five stories.

That room is located next to restrooms and an elevator.

How Cory Barron, 22, ended up in the trash room -- behind a pair of double doors -- during a Friday night Jason Aldean concert remains a mystery. Investigators have said little about the circumstances leading up to his disappearance, only the he was with family and was drinking heavily.

The Fremont resident fell to his death in one of those trash chutes.

The original blueprints for Jacobs Field were submitted to the city of Cleveland in 1992, two years before construction ended. The plans don't reflect any renovations made in subsequent years, said Jim Kopniske, communications director for Cleveland.

Police confirmed that the chute they believe Barron, 22, fell into was in the stadium's northwest corner near the restrooms and the elevator.

Stadium plans show a small room in the northwest corner of the main concourse level with two chutes that fall five stories straight down. The room is next to an elevator and the men's and women's bathrooms and is only accessible through a pair of double doors.

Barron's seat at a Jason Aldean concert Friday was in the upper deck in the northwest corner of the stadium, police said.
