Those three Polaroids taken by Officer Barringer.

Well, did you look at them in 95?

No.

Why not?

Didn't know they existed.

The Polaroids were taken before Donna and Harrington were moved to the hospital, but were never shown to investigators.

When the detectives finally saw these photos, they were flabbergasted.

It didn't take but 10 seconds.

It was a smoking gun.

It was the smoking gun.

Why?

Roger Harrington's body, the placement of that body in that photo, blew Mark's story out of the water.

It was over.

Roger Harrington's head and feet were in the opposite way of what Mark told us happened.

In the chaos, detectives did not have time to note for themselves where Donna and Harrington lay before paramedics rushed them to the ambulance.

To understand why the police now thought Winger had to be lying requires a little forensic fancy footwork.

Charlie Cox went with us to the Winger's old house to demonstrate.

The story that Winger told us, Mr. Harrington would have been lying

basically like this.

Because he would have fallen backwards when he was shot and landed that way.
