Yeah, just a few days ago the train I was on in Sweden killed someone but I couldn't find any reporting on it in any media.
We will most probably never know what happened. Also, you usually hear through one sort of info or the other when something like that happens in Austria; but as I said, we will likely never know what happens.
Zell am See has 10.000 people, there can not be that many Rolands, so you could likely find him by looking him up on the phone book if they incl. mobile phones in Austria.
