The Kill List
I was the D.A. back then in 1998, and... I was at the Kenosha Heart Ball. My page went off, and then they sent me to the Jensen residence. So I was wearing a tuxedo when I responded to the crime scene.

The Kill List
I knew it was going to be a difficult case because standing at the foot of Julie's bed, I didn't see any obvious things that caused her death. There were no stab wounds. There were no bruising. There was no battery wounds. There was no gunshot wounds. She was apparently a healthy woman lying dead in her bed.
20/20
The Kill List
We don't know how she died. There's no obvious cause of injury. Every suspicious death is to be treated as a homicide and investigated as a homicide until homicide is ruled out. So what we need to do is get consent to search. Then I went and spoke with Mark Jensen. He gave his consent to search.

I pointed out, you know, we are going to be taking that computer. It was rare to have a computer in a home. There were computers that were in offices, but the first time we'd ever taken a computer out of a private residence.

The Kill List
There's a really telling email exchange between Kelly and Mark in mid-October of 1998. He says, hey, would you like to run off somewhere? She's, of course, thinking about divorcing her husband.
20/20
The Kill List
I think Mark Jensen's dishonesty and evasiveness and sneakiness came through in that interview, particularly when he was asked about Kelly Labonte.
20/20
The Kill List
Mark lied about Kelly. He lied to police about Kelly. He said that, oh no, we weren't having an affair.

The Kill List
i viewed it as julie's last will and testament you know i felt that this was her testamentary request that if something were to happen to her she wants people to know i would never commit suicide my boys are everything to me and my husband would be my first suspect months after julie's death they interrogate mark in a little interrogation room in the pleasant prairie police department

The Kill List
There was a question between myself and the kids that morning whether or not to call an ambulance.
20/20
The Kill List
She told her neighbor, Ted Voight, that she thought her husband might be either planning to kill her or doing these things to make it look like he was planning to kill her to cause her to do something so that he could then make her look like she's crazy and take her children away.
20/20
The Kill List
What Julie was really terrified of, I mean, she was afraid of being murdered, but she was even more terrified of Mark divorcing her and taking her children away from her.

The Kill List
The computer was sent to the crime lab the next day, but we didn't get the analysis done until months later.
20/20
The Kill List
That is for poisoning. He thought he deleted everything off this computer, not realizing that when you delete things, they don't actually go away.
20/20
The Kill List
That is correct, yes. They're still there on the hard drive of the computer, which we were able to recover. He didn't know that was going to happen.
20/20
The Kill List
It's a horrible, horrible, horrible way to die. You start to have difficulty breathing. You're very sick and nauseous. Your kidneys shut down.
20/20
The Kill List
It wasn't a family computer. It was Mark Jensen's computer. It was Mark Jensen's computer in Mark Jensen's den.
20/20
The Kill List
I was the DA back then in 1998, and I responded to that crime scene. Over the next two or three years, I would take this case to prosecutors' conferences with me. I'd lay out the facts. And the overwhelming response I got was that there's not enough to charge this case out.
20/20
The Kill List
I read in the newspaper that Mark Jensen was marrying Kelly Labonte, and I said, you know, this case isn't going to get any better, and that could be victim number two. We've got to charge this case out. You were worried that Mark Jensen could kill again. Yes, could kill. I mean, I thought he would kill again.
20/20
The Kill List
Mark Jensen had told him in November of 1998 how to kill your wife. You'd feed her Benadryl and you'd mix it with another drug that would crystallize you from the inside out, which is what antifreeze does.
20/20
The Kill List
In some ways, it's a better case without the letter. It's a cleaner case without the letter. But I said, you know, one of the reasons I want to put this letter in is because this is Julie's voice. And I think this victim deserves to be heard.
20/20
The Kill List
I know the evidence in this case because it wasn't just Detective Ratzberg that responded on December 3rd, 1998. I was there too.
20/20
The Kill List
Did he tell you what happened when he sat on her and with her face pushed into the pillow?
20/20
The Kill List
She wasn't dying quickly enough because he'd promised the children that he would take mommy to the hospital. He had to make sure she was dead before the kids got home.

The Kill List
There were computers that were in offices, but it was rare to have a computer in a home.

Here we are today, 24 years, one month, 28 days after the homicide of Julie Jensen.
