A look ahead: The Devil Inside

(WMC-TV) - Action News 5 speaks with a woman who has known Adam Mayes since the beginning...

"Adam was very much a mind manipulator, he would say something he wanted you to do in a way that would make you want to do it," said his sister. "I expected one of my brothers or sisters to snap, I just didn't know which one."

In an Action News five exclusive, hear the bombshell family secrets that set the plan into motion.

"They were going to cut off ties and I think Adam panicked because he didn't want to lose those two girls," his sister claimed.

Hear more from the woman who has known Mayes since he was a child, Thursday at 10 p.m. on Action News 5.
