This window is at an old motel that Bonnie and Clyde stayed in. This is in Decatur, Texas. I don't know who wrote redrum on the window, but I knew what it meant.
Redrum is murder spelled backwards or if you see it in a mirror as in the movie The Shining. A very good thriller. I always thought of the lyrics from Hotel California during this movie. You can check in but you can never leave.
