I live in Indiana. My wife was on a college campus, studying for classes and she tried to open a window in the room she was studying in. The building is older, as a lot of campuses are, and her hand went through the window nicking her radial artery and several other lacerations that caused a lot of bleeding leading to an emergency room visit via ambulance. There were no signs posted signifying that windows were not to be opened. So now we are stuck with medical bills. Is the campus liable, how should I handle this? I can't afford all these bills.
