The most horrible thing you could ever imagine, woman's asleep in her own room, in her own bed,

and she's awakened to being stabbed. She's laying right here, whoever it was starts stabbing her.

Joanne Witt lived alone in the home with her 14-year-old daughter Tyler Witt.

Joanne had 20 stab wounds over her entire body. It's one of the most horrific wounds I've ever seen.

It was very brutal.

It didn't appear that there was a robbery involved.

There was nothing else missing from the home.

And then the next question was, where's the daughter?

And then wait a minute, where's the daughter's boyfriend?

Where are they?

It was a very devastating experience. My daughter is

murdered and we don't know what happened. The next thing we know, they're telling us that our

granddaughter and her boyfriend did it. The relationship she had with Stephen Colvert,

she worshipped him. She would have done anything for him.

She was turning into more of a rebellious teenager.

She was testing the limits.

She'd been getting into trouble.

You've been arrested for murder.

What?

Who did I murder?

Your mother.

What?
