And I anticipate that there will never be any charges filed against Mr. Winger.

Yeah, I was fine with that.

Case closed.

Case was closed before then.

There was an outpouring of support for Mark here in Springfield.

Almost everyone believed he was a good family man whose life had been shattered by a madman.

But one family wasn't buying that story at all.

Roger Harrington's family.

Harrington's sister, Barbara Howell, pleaded with Detective Cox.

Roger's mother, Helen, felt the shame of a city that believed she had raised a psychotic killer.

You felt branded.

The Harringtons bore their grief quietly, believing they were alone.

They didn't realize that someone else doubted Winger's story, someone close to the investigation.

How convincing was Mark Winger that night and the night after?

It was very convincing.

Detective Doug Williamson.

Were you convinced?

Williamson had a lot of questions.

Why would Donna leave her baby alone on her bed and open the door to Harrington, a man she supposedly feared?

Roger Harrington was allowed into the house.
