A while ago, I read a thread regarding Edberg killing a man (of course, by accident). He was young and playing a junior Wimbledon or something. His serve hit a linesman and he died unfortunately. Did it really happen?
Edberg's serve hit the lines-person who was sitting on a chair (was sitting duck), the line person fell down from the chair and struck his head against the hard surface of the U.S. Open. After that accident, the lines-persons watching side lines and the center service line were required to stand so that they are able to move in case a missile comes at them.
