Prey; sufferer (6)
I believe the answer is:
victim
I believe this is a double definition.
'prey' is the first definition.
(I've seen this in another clue)
'sufferer' is the second definition.
(I've seen this before)
(Other definitions for victim that I've seen before include "One who suffers the crime" , "One suffers from adverse circumstances" , "One killed, hurt or duped" , "Person who has been injured or swindled" , "Person tricked, swindled or wronged" .)
