Homicide (6)
I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">homicide</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that homicide can be written as murder)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for murder that I've seen before include "a number of crows?" , "Kill" , "Situation causing hardship" , "Dispatch" , "Serious crime (that may be blue?)" .)
