Believed to be guilty (9)
I believe the answer is:
suspected
'believed to be guilty' is the definition.
('suspect' can be a synonym of 'believe to be guilty')
This is all the clue.
(Other definitions for suspected that I've seen before include "Fancied" , "Believed likely or distrusted" , "Felt" , "Believed (someone) guilty" , "Believed to be guilty but without proof" .)
