I would never take my life because of my kids. They are everything to me.

The evidence is abundantly clear that Mark Jensen in a very cold and calculated fashion murdered his wife. It is just the most cold-blooded case I've ever seen.

You believe she was murdered? This is a poisoner, a poisoning murder case. And poisoners are a different breed of murderers.

It is phony. So the fact that Dan Jensen or Florence Jensen say they believe something, that carries no weight with me at all. They're both a couple of liars.

He kills the witness, and then he complains because he can't cross-examine her. That's the definition of chutzpah.

We fought hard to get this letter into evidence. By God, her words should be heard by that jury.

December 3, 1998, I was summoned by the Pleasant Prairie Police Department to this residence. My name is Robert Chambois, and I'm the special prosecutor.

He wanted to stay out of this. He didn't want to get involved. Not exactly heroic, was he? Well, I'm not putting him up for hero of the year.

It certainly was not death by natural causes. We considered that it could have been a suicide. Julie had written a letter.

And I'm writing this on Saturday, November 21st, 1998. If anything happens to me, he would be my first suspect.

She was poisoned with ethylene glycol, and it may have killed her, except we now have very good reason, very good evidence that what actually killed her was Mark Jensen sitting on her in that weakened state, shoving her face in a pillow and suffocating her, and that's what I believe happened.

Oh, the nose was off to one side. The mouth was off to one side, like she'd been shoved into something. People don't sleep like that. So she was put in this position. Somebody put her like this.

Would you like to try a swiff of ethylene glycol right now?

In my view, it was almost like her last will and testament.

Please take a taste of it.

So how did that taste?

What is your opinion to reasonably of medical certainty as to the cause of Julie Jensen's death?

We think more, we're not sure.

I would not buy a used car from him.

You wanna know why the jury's gonna believe him? Because he's telling the truth.

As soon as he had somebody available, as soon as he had somebody on tap to replace her, bang, she was out of the picture.

If Mark Jensen didn't murder Julie and she committed suicide, I just wanted to be able to prove it.

For nine years, I've been trying to tell a jury about what happened to Julie Jensen. She expresses her pain.

She wanted the world to know the truth. She wanted you to know the truth. At the time she wrote these words, Julie Jensen had no motive to lie.

My pager went off. I got called to the scene. And they told me, the M.E. is saying it's probably natural causes, but we have some questions, so you might want to come out.

40-year-old women don't just drop dead for no reason.

We absolutely considered that right from the very beginning.

That letter reinforced the suspicions that I'd had the night before.

The computer was a treasure trove of inculpatory evidence. First of all, it showed us the motive because there were the emails between Mark and Kelly. We did know that Mark had a girlfriend on the side at this time.

IDLY means I do love you, and then she's got IDLY2, and then I am one, and IWY, I miss you, I want you.

Absolutely not.

He was looking up ways to kill his wife on the computer.
