If Kenneth Biros is put to death as scheduled December 8th, will questions about unsolved murders die with him?

In the 90's several police departments in Mahoning County and Pennsylvania thought he might be a suspect in cases where women were cut and injured then had their intestines or body parts cut out. Biros tortured, raped, murdered then dismembered Tami Engstrom, a 22-year-old mother from Hubbard.

Prosecutor Dennis Watkins says Biros own psychologist found he had a schizoid personality. That is someone who has a quest for the painful destruction of other human beings.

He stopped short of calling Biros a serial killer saying he can't prove it, but in a letter to the first parole board Watkins came close.

"The facts show he is an incipient serial killer, an educated loner who kept to himself and hated women," says Watkins. "That was my opinion. It is my opinion today. It will never change."

Those cases have never been solved. Prosecutor Watkins points out the YSU graduate took classes in criminology and forensics and knew how to destroy evidence.
