Poor Bethany Lott; poor Richard Butler, who would have married her; and poor headline writer who penned this appalling crash blossom:
Bethany Lott killed while being proposed to by a lightning strike in Knoxville
Bethany was not proposed to by a lightning strike. She would have been proposed to by her boyfriend Richard Butler, who took her hiking in the North Carolina mountains that she loved and planned to pop the question when they reached the top. Three lightning strikes homed in on them, and the third scored a direct hit, killing her and wounding him. The story is here. And what a disaster of a headline it got.
The writer's syntactic problem was simply the ordering of three preposition phrases: (1) the temporal adjunct while being proposed to; (2) the passive complement by a lightning strike; and (3) the locative adjunct in Knoxville. All that was needed was to order complements before adjuncts, and locative before temporal adjuncts, as normal in English, and everything would have been hunky dory: Bethany Lott killed by a lightning strike in Knoxville while being proposed to.
That would still have been false (Richard never got to tell her he wanted to marry her; after her last words "Look at how beautiful it is" she was promptly killed by the lightning bolt), but at least it wouldn't have tainted a very sad romantic story with a catastrophically ludicrous ambiguity.
This is the sort of crash blossom that makes you wonder if news sources don't make them up deliberately to have fun, giggling to each other about overcharging the dead, missing women police, batter markets, drinking rockets, and so on.
