1791 Criminal records for Yahualica, Jal.?

I have located what I think is the burial record for my 5ggmo, Catarina
Perez, on 17 Jul. 1791. It states "no se administro pax su muerte tan
violenta", which suggests to me that she may have been murdered so there may
be a trial associated with her death. Can anyone guide me towards the
location of criminal records for this location and period? Thanks so much.
