Cut up as daughter falls, being murdered (4)
I believe the answer is:
iced
'being murdered' is the definition.
(ice can informally mean to murder)
'cut up as daughter falls' is the wordplay.
I cannot really see how this works, but
'daughter' could be 'd' (genealogical abbreviation) and 'd' is present in the answer.
The remaining letters 'ice' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
(Other definitions for iced that I've seen before include "Dressed in a sweet coat" , "Chilled - killed" , "Finished off cake" , "Having a sugary coating" , "found thus in freezer?" .)
