Since I find this story interesting and I want more info I have compiled a few links. One is to a more in depth story from another site. http://thefreethoughtproject.com/activist-stabbed-death-house-set-fire-predicted-cops-kill/

Here is the link to the site listed in the article, appears to be his letter documenting it all. it's a bit rambling but here it is. https://archive.is/cBYn0

Here is most of what is in the archive link above but a little easier to read and with the videos embedded. http://fresnopeoplesmedia.com/2016/01/2829/
