I believe the answer is:
abel
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">first homicide victim</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for abel that I've seen before include "Cain's 11" , "Adam's boy" , "Cain's victim; - Magwitch (Great Expectations)" , "Bale out with murder victim" , "Victim of murderer" .)
