Serial Killer John Fautenberry

Would you recognize a serial killer if you rubbed elbows with him in a bar or if he struck up a conversation with you on a hiking trail? Maybe something about the person would set off alarm bells, especially if you found yourself alone with him. A sociopath or a psychopath can often present a charming demeanor, though, so most of us would never notice the predator in our midst. We might not realize the friendly stranger is a brutal murderer until we read the news the next day.
