BAD ROMANCE.

MATT GUTMAN (ABC NEWS) (Voiceover) I'm traveling to the Gatesville Correctional Facility, about an hour west of Waco. I'm there to meet Wendi Mae Davidson, the former veterinarian, current convicted murderer. From day one, she has insisted she wasn't responsible for the death of her husband, Staff Sergeant Michael Severance. When you do interviews like this, you always wonder what it's going to be like looking into the eyes of a killer. But Wendi doesn't look or act like any of the killers I've talked to. I'm gonna cut to the chase and get right to business. The first question is, you know, you basically kept your silence for 15 years. Why did you decide to do this first network interview?
