Utterance duplicated in the Coroner’s records (3)

I believe the answer is:

cor

I'm a little stuck... Click here to teach me more about this clue!

'utterance duplicated' is the definition.
I can't judge whether this defines the answer.

'in the coroner's records' is the wordplay.
'in' indicates the answer is hidden within the clue.
'COR' is hidden within 'coroner records'.

Can you help me to learn more?

(Other definitions for cor that I've seen before include "Expression of surprise" , "Gosh" , "Blimey" , "Surprised expression" .)

I've seen this clue in the Evening Standard.
