'completed his sentence' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'cops' mole at fault in trouble' is the wordplay.
'in trouble' indicates an anagram.
'cops'+'mole'+'at'+'fault'='copsmoleatfault'
'copsmoleatfault' with letters rearranged gives 'CAME TO A FULL STOP'.
