A Wisconsin woman has filed a lawsuit against a concert venue in Milwaukee after she fell down the stairs while trying to leave the concert. The woman claims in her lawsuit she was walking down the stairs when the lights suddenly went off for an encore, making it impossible to see. The loss of light caused her to fall and suffer injuries to her head, neck, back, leg and arm, the suit says. The lawsuit alleges negligence on the part of the Bradley Center and concert promoter Live Nation.
