I have read different stories of why they were massacred. Such as one of the men raped a Native American woman or the Native American's became angree when they saw 80 or more mexican miners that might be taking over their land. I also have read some where that a Jesuit priest or priests killed and buried the N.A. with the treasure so there wouldn't be any witnesses ( dead men don't tell tales ). A young N.A. saw what happened and told what had happened. The treasure site became a sacred burial site and has been watched since the killing happened. I believe that the Peraltas while prospecting or knowingly looking for the treasure, found the treasure site/sacred burial site, They may have disturbed the site and the call went out, of course we know what happened next. Are there any other stories or opinions?
