A man who is in prison for killing a prostitute in 2007 is now suspected of murdering at least three more across the South.

John Boyer, a long-haul trucker, is currently serving a 12 year sentence after pleading guilty to killing a prostitute named Scarlett Wood in Wilmington, North Carolina, but in the last few months he has confessed to killing even more women throughout the Southeast and faces murder charges in Tennessee and South Carolina.

His demeanor is so violent that even his own attorney suspects that there may be more victims who were murdered.  “It wouldn’t surprise me if there’s other stuff out there,” H. Lawrence Shortwell said.  “I have absolutely nothing other than a gut instinct on that.”
