(NewsNation) — The search for Vicky White and Casey White, and their eventual capture, captivated the nation. And while many have been left baffled by the motivations in this case, Toby Dorr knows exactly how it can happen.

In 2006, Dorr, previously known as Toby Young, did the same thing.

At the time, she was married and running a volunteer dog training program at a state prison in Kansas.

That’s where she met John Manard, who was serving a life sentence for a deadly carjacking.

“You’re at a point in your life where you just feel invisible, and you feel broken, and you feel so alone and lonely,” Dorr said. “When somebody notices, common sense just goes right out the door.”
