Medical examiner may take this slander (5)
I believe the answer is:
smear
I believe this clue is a double definition.
'medical examiner may take this' is the first definition.
(I've seen this before)
'slander' is the second definition.
(I know that smear is a type of slander)
(Other definitions for smear that I've seen before include "Blur, smudge" , "nasty mark" , "False accusation; blur" , "False report" , "Badmouth" .)
