I wish he would be cleared as well, but I don't know if Stearns will take the time and resources to do that. I don't think the FBI has bluffed on Rassier at all, it's all Stearns County from what I can tell. Stearns has always led the investigation and are the ones who focused on DR since 2003...FBI only served a support role until taking over the case in November 2014. Things happened pretty quickly at that point.
What about all of those other agencies involved? The BCA was reviewing the case in 2010 and they apparently found the info for a warrant?
