"Virginia Beach man accused of decapitating son to stay in hospital", (Newport News) Daily Press, 9/26/2011.
In this case, there's both a syntactic-grouping ambiguity and a functional ambiguity — the headline is meant to be interpreted as
[[(a) Virginia Beach man [(who is) accused of decapitating (his) son]] [(is) to stay in (the) hospital]]
but readers are likely to parse it first as
[(a) Virginia Beach man [is accused of [decapitating (his) son [(in order) to stay in (the) hospital]]]]
