This is a little out of the jurisdiction of the City of Fresno. In fact, it's not even in Fresno County. It is in Tulare County.
The Fresno Sheriff's Department did investigate the murder of their officer, which did occur in Fresno County, but they would have no cause or jurisdiction to look into anything else. If anything is going on up there it is up to the FBI to keep on top of it, and they aren't going to be telling us what they are doing.
Also, isn't this group's charter school that has received about 1 million $'s in Fresno. I believe that it is supposed to get close to 4 million $'s next year!
