Haley Sisco

Tonight on Dateline. There was tape all around the property. My grandma told me that my dad and Karen's been shot and killed.

I wasn't home when he wanted me to come home, and I was just really, I was really doing my own thing. So you were fighting with your dad? Yeah.

He did spend a lot of time with Karen, and so me and Mike, I felt like I was, I wasn't replaced, but I wasn't as special.

Your dad, at the time, didn't think you were ready for this serious relationship? Well, me and Chris hung out a lot, and my dad didn't really like Chris.

My dad told me that I needed to follow his rules, be home at curfew and that kind of thing, or I'd have to move out. And so... I moved in with Chris and his family.

I've been thinking about it because they went to the casino the night before, and they would have won a lot of money.

Help me.

He loved being in the mountains and just hiking, you know, fishing and camping and all that stuff. He taught us how to do all of it. I remember I would, you know, hook my own worm and unhook my own fish. I mean, we were really into it.

She had the nice car, and she always wanted to look nice. And she was very busy. Would you describe it as kind of a typical family? Yeah. We had a backyard with the dog. We had the sandbox. All the fun stuff, you know, as kids.

There was always just arguing, you know, just like the constant tone of the household that we were just accustomed to because that's all we knew. Mike and Dana were married for about 15 years when they got divorced. They tried to get back together and make it work. It just didn't last very long.

The custody was a battle. My mom really wanted us. My dad really wanted us. My mom was found to be really unhealthy and was drinking quite a bit at the time. And so when my dad got custody, she moved to live with her sister to try to get a handle on her alcohol problems.

So she was regularly using her phone.

I'm sure your stomach is turning.

This is the mother-daughter showdown for the ages.

Thank you.

Thank you.

Thank you.

for your mom to be arrested.

I was really scared because she was going to find out that I had been recording our conversations. So arresting her and taking her to trial was great.

It was terrifying. And it was very awkward. And it was hard to not feel like you are doing something totally wrong and betraying your mom. But I was only doing what was right. If you believe she did this, then she has to pay. Yeah. I wanted the jury to know how much she hated them, what she put them through, and... Karen and Mike. Yeah.

I felt like my life was starting. You know, that was behind me. And this was the new fresh start, a new beginning. Chris and I got married and we started having kids and it was great.

Yeah. Yeah. the Kansas Supreme Court overturned the conviction.

I was terrified if she would get out of jail. And I had kids now. Yeah, could she harm one of your children? Yeah. Was that a fear? Harming them or just trying to see them in general.

My mom looked so different. I mean, she'd been in jail for 11 years, and it was still hard to see her. But, you know, time had passed, and I had grown, and So I think it was a little bit easier.

Yeah.

I wanted the truth. I'm telling the truth, and I'm doing the right thing, and I'm not moving.

Wow. Shocking. This is the mother-daughter showdown for the ages. Absolutely.

I was really nervous about her getting out on bond. I felt better because she was supposed to stay in Kansas and she'd have an ankle monitor, but still, I knew it was nothing for her to drive any distance.

Knowing that I was going to have to get up on the stand and be questioned by her was like upsetting my stomach to have to talk to her.

I put on my game face. I remember right before I went in to testify, I remembered like a soccer pep talk that my dad gave me as a kid to get ready for the big game. because I needed to be my best, and I needed to be ready for a fight, and just like, I can do this, you know? And I remember reminding myself where I stand. I wanted the truth.

I wanted the truth. There's finally an arrest.

I'm telling the truth, and I'm doing the right thing, and I'm not moving.

No, he did not. And I'm like, no, that did not happen. She was making things up.

Yeah, yeah, guilty. Does it feel even better this time around because of everything you've been through that maybe this is final now?

Yes. This time with her representing herself, exposing herself with all of her stories, I feel it is over. It's fully out there. Everyone knows what happened.

He would have made, like, the best grandpa to my kids. And Karen would have been a great grandma, too.

I hope my dad's proud of me. That's all I wanted.

My grandma called me and just asked me if I could come to Karen's house. And I said, sure. Mike's daughter, Haley, was 17 at the time. When I got to Karen's, there was tape all around the property. What a shock to the system. Yeah. What are you thinking? I honestly didn't even think, you know, there was something going on at Karen's house.

And I sat down, and I think it was my grandma that told me that they had been shot and killed. My gosh. Your reaction to that, I mean, just unbelievable. It was unbelievable. I was just in shock. I don't think I said two words.

You have to testify. It was terrifying. I put on my game face. You're not going to intimidate me.
