On Tuesday, at the Washington Highlands Interim Library, a deer jumped through a window and ran wildly inside (video below).
Library staff member Mariah Perry said when people first saw the deer laying on the ground, they were uncertain just what kind of animal it was.
But when the deer got up and charged, Perry said she and her colleague ran for the back of the library screaming and barricaded themselves behind a door.
The librarians called police, and then police called animal control.
The deer suffered a broken jaw from the break in and was later euthanized by animal control. Officials hoped to reopen the library on Wednesday afternoon.
