I am trying to find a movie, which is B&W. I recall at the beginning of the film that a young couple were having an auguement about something, the woman left the house to go to the movies, as she was leaving she sees a robbery in progress. She is spotted by one of the gang, she runs off and straight in front of a bus. She is taken to hospital where she is unconscious. The thieves go to the hospital and try to finish her off, but an old lady keeps calling the nurse, saying there's a man trying to kill her. One of the thieves has an hearing aid. When I use to see this film it was always shown as a Sunday Matinée. I would like this film for my DVD collection. Can anyone advise me on a suggested title?

Eyewitness (1956) (http://www.imdb.com/title/tt0049196/)
