David Coffin was a 41-year-old male who was full of life, very attractive, a lot of fun.

I think he's very smart, but he's impulsive.

And when I looked at everything, I was literally disgusted. I was disgusted that he had gotten away with it.

The defendant is wealthy. and let's face it, he's wealthy and comes from a very good family here in Atlanta and that creates a whole new dynamic. It's a different dynamic because wealthy people have advantages that poor people do not have and they work the legal system.

Flames were shooting out of his roof 20 to 30 feet in the air. When they got the fire under control, they walked through once, found nothing, walked through the second time, and actually a firefighter stepped on the body of David Coffin. People who die from the fire, they're usually found on their stomachs because they're trying to crawl out of the house.

He was a competitive man who wasn't going to lose his wife to the likes of David Coffin. And he targeted the competition. He hunted his competition. He stalked his competition. And he ultimately killed him.

How important is Megan to this case? Megan is the motive. I think the case would have been very difficult without her. Sorry.

And was David there?

He was on his back when they discovered him. That led the firefighters to believe that he did not die from the fire, that this was a murder case. He literally was just executed in cold blood. All that remained of David Coffin was charred remains. My name is Sheila Ross. I'm an assistant district attorney in Atlanta, Georgia.

Like he's being haunted by the ghost of David Coffin. And he started realizing all the mistakes that he may have made in perpetrating the crime. And then he impulsively tries to cover up what he had done.

It's his impulsiveness that did him in, because he's always trying to outthink the police. He's trying to outthink everybody, outsmart everybody. Good morning.

Scott Davis may not have lit the actual match to the Porsche. Do you today believe it's possible that somebody else helped him? I absolutely believe that it is possible that somebody else helped him, yes.

The fire to David Coffin's body and to his home was very, very devastating and destructive. We're talking no hairs, no fibers, no DNA, no fingerprints from any of the things that came from the home.

I told them to expect anything.

That anything is possible.

And just brace for impact.

It's the hardest case I have ever fought in my entire career.
