I was going to say that maybe it was the work of the man who killed the people on that Christmas tree farm in Ashe County, NC, Frederick Hammer. But then I realized he was arrested last year and the murders have continued.
He killed 3 men in that incident and later confessed to killing his nephew, Jimmy Blevins. He led police to his body. He also confessed to killing another man, Timothy Shatley. Most of these were over money. A news story that came on at the time of his arrest said that he claims that he has murdered 17 people, but at the time they weren't commenting further on his claim because the others couldn't be proved. He was sentenced to 7 life sentences earlier this year for the Christmas tree farm slayings.
(This case has fascinated me because my grandmother and my aunt's family live in Ashe County near to this farm.)
I would like to think that they are going to investigate this Rocky Mount case and the above confession with due diligence. The idea that there are/were 2 serial killers that close to home is very disturbing.
I'll be keeping these woman and their families in my thoughts. I hope they arrest the guy they have as a possible suspect soon if he really is a valid suspect.
