Toni Hartzong

Her nail might have gotten into an old cut.

I don't know.

Then there is the other critical piece of evidence.

Bob's DNA was found on the palm of Tony's right hand.

Bob admitted touching Tony when he found her body here in the doorway of the Hartsong's home.

But did he just touch her or did he bleed on her?

It becomes a key question because if Bob's blood is on Tony's palm, it almost certainly got there the day of the murder.

She didn't leave the house with blood on her hand.

No woman does.

If she noticed there was blood on her hand, she has immaculate hands.

She would have washed it off.

A blood expert testifies about the breakdown of DNA on Tony's palm.

She says it's a mixture of Bob and Tony's DNA, and some of it is blood.

Barry Sorin takes this to mean it's Bob's blood.

And after eight long years, he thinks his sister's murder has finally been solved.

I cannot find a way out for Bob.

He had to have done this.

I'm sorry to say that.

But Bob's defense attorney says the blood evidence isn't conclusive at all.

and he's about to punch some big holes in the prosecution's case.
