It does seem likely to be an inquest. After a very quick look up, the numbers listed and the terms used could refer to a local judiciary company who may have conducted it. If so, it is worth pursuing to see if we can access the findings of the inquest, since there may be records relating to the reference number. I'm not an expert in legal issues let alone Spanish so I have no idea how difficult it would be to get access. Nothing to be lost by trying though.
I'll have a look at your message.
