Coroners Reports

Hello.  My gggrandfather died in Hong Kong in 1858 where he served as a member of the Medical Staff Corps.  I have some details (including his death and burial date) but he was accidentally killed and I believe there was a coroners report. I have searched the HK Public Record Office but am unable to find coroners reports.  Can anyone point me in the right direction?

Many thanks, tomcrean
