Killed with scattered nails (5)
I believe the answer is:
slain
'killed' is the definition.
(slaying is a kind of killing)
'scattered nails' is the wordplay.
'scattered' indicates an anagram.
'nails' anagrammed gives 'SLAIN'.
'with' is the link.
(Other definitions for slain that I've seen before include "Slaughtered" , "Put to the sword" , "Violently killed" , "Killed, murdered" .)
