Pretty good run down of events here.

April 21 Unicoi TN Sheriffs Dept are looking for him. This is after he assaulted hikers in Madison Ct NC and Devil's Fork Gap. Both he Sheriff's Dept and USFS had gotten calls about him and he was ID'd by his trail name with a description.
April 22 Madison County Sheriff's Dept makes contact, determines he's not a threat, and releases him.
April 23 Unicoi Sheriff's Dept arrests him for assault and drug charges after what looks like 2 more incidents in TN on Laurel Rector Rd and Sam's Gap.
April 26 he pleads on criminal impersonation, drugs, and public intoxication. Fine, probation, and released.
May 11 he is arrested for murder and attempted murder in Wythe County VA.
They are still investigating whether there were more incidents. As tight as the hiker community is, I doubt there are other victims. At least not on trail.
So the tally is 3 Sheriff's Depts and the USFS get calls about this guy and I'm guessing most of this happens in a vacuum with little to no communication of it to other agencies. Dept 4 ends up with a murder and attempted murder in their jurisdiction. As an average citizen it makes me scratch my head how this guy bounces around causing these issues with nothing more than a fine and probation to show for it. Damn shame as far as I'm concerned. If the guy snapped one day and did it, I might be able to chalk it up as people need to just watch out for themselves. As it stands, it's a testament to the slow nature and lack of foresight of the system that you don't need to be counting on. When a guy spends a week threatening and assaulting people it should really be more of a red flag. Yes you need to take care of yourself, but let's face it, the media and a lot of LE have done a good job of communicating that it's their job even if they can't possibly do it. It's no wonder people expect them to be there. They say they will be.
