It's still hard to make out every word, but the official police transcript notes that Bruno and Melissa can be heard cursing and calling each other names.

The transcript also notes the sound of a dog barking.

Then Melissa shouts, I didn't do anything.

Listen closely.

Nearly 30 minutes after they first pulled into the driveway, Melissa told Bruno that he had to leave because of something he'd previously done hundreds of times, said Melissa.

A bit later, Melissa can be heard talking.

Then it sounds like things are being thrown.

Just seconds later, the gun goes off.

Joanne says she hasn't been able to listen to the recording, but has read the transcript.

I was horrified.

Of course I cried.

Also horrifying is the sound of Chelsea screaming after her father called her over and she first discovered her mother.

She says she doesn't remember questioning her father that night, but she did.

And Bruno's answer gave police yet another version of his story.

He implied that Melissa had been the one holding the gun.

A little over two weeks later, Mark Powell says forensic expert Dr. Wayne Ross confirmed what Greg Allen and Dan Nylon had suspected about how all the blood got on the wall behind Bruno.

And so where do you say Bruno was at that time?

The theory is that Melissa tried to escape Bruno's grip, and there was a struggle.

What do you think your sister would say about all of this?

If she was here, she would say, lock his ass up and get away from my kids and my grandkids.
