Has any one who's ever died of thirst because they where locked in a room with no way out?

this has always bugged me, you know how you always hear stories about people who accidentally gety locked in storerooms or say have their hand trapped behind a pip and couldn't move for several days well most of these types of stories end with them being found by the janitor or something and them getting out... but why do you you never hear stories about people who've been trapped some where and died, and why do people on the news never specify that if not found dehydration is what found have killed them....I mean it is isn't?
