The real funny part is how the media has backtracked by mocking the sheriff. They are chuckling about how they were just head-faked by a bumpkin constable. I'm sure the reality is closer to: weirdo calls in a "tip" that there are loads of bodies in a mass grave. Responsible sheriff's office checks it out. Over eager media pounce on info obtained over scanner, or the weirdo who called in the tip calls the media as well.
What was the sheriff supposed to do? Ignore the call?
From first reports, tipster apparently called 3 news outlets and the sheriff.
News media apparently ran with the tip and then tried to blame the sheriffs office.
