Transcript for Michael Lee Jones is arrested as Inna Butnytska has a breakthrough: Part 9
Since Inna was found assaulted and abandoned in that field, her memory has been foggy, all over the map. But suddenly, she's got a breakthrough. I tried to bring myself back in to the accident and see if I can remember something else, small details. She came to my office and said she didn't know if she was dreaming or if it was a reality. But she remembers being in the hotel room and sitting on the bed and across from her was a black male. Wow. Wow is right. So I put together a photo lineup with Michael Lee Jones in it, and I just tell her, "Tell me if you recognize any of them for any reason." And I chose a person from the lineup. This is the person who basically, who raped me, I said. She goes right for Michael Lee Jones. Finally, it all seems to be coming together. And the DNA results have arrived. I called Ken up, I says, "You are not gonna believe this." He goes, "It's him." I go, "No kidding." Yeah, yeah, it's -- I knew it was him. What was that moment like? Oh, it was total elation. I was happy. So the next step would be to make an arrest. Yes. I get an arrest warrant. And then I go back to Maryland. I meet up with Ken and members of the Frederick police department. And we go out to Michael's apartment. We are caravaning like John Wayne and the wagon train, where the cavalry is coming, 'cause we are gonna go get our guy. And we go to his apartment. We knock on the door, and he comes to the door and he answers, and we look at each other face to face, and I said, I told you I'd be back. You are being charged with rape, all right? She says I raped her? We already have the hit on the DNA, okay? Now it's just a question of interrogating him and seeing if I can get this guy to roll on it right. Look at these. , I didn't do that. You were there. I did not do that. You show suspects pictures of victims, because what you're trying to do is humanize the victim in the eyes of the offender. The problem is, it doesn't tend to work, because they don't Once we started to throw the fact that, you know, obviously he was under arrest for this kidnapping and rape, his story changed. Just give us your version of what went down. Now, you only get one chance at it. All right, I am gonna be straight up. I know the only thing he's going to come up with is, she was a prostitute, I paid for her, she was fine when I left her, I have no idea what happened to her, okay. Jones says that he and a friend, that guy in the Mercury t-shirt, went out to a strip club that night. That when he returned to the hotel, that he did see Inna hanging out with some women in front of the hotel. Obviously they were hookers or whatever. And you know, we were talking to her like, you know, "What to have some fun?" And then what happens next? Did you go to her room? Did she go to your room? We went to her room. You went to her room? Uh-huh. And then, you know, she -- she whispers in my ear, "A hundred bucks." So we did it, and we gave her a hundred bucks and I left. The offender is trying to steer them in another direction. Yes, I'll admit I had sex with her, but you can't prove anything beyond that. Is easy victim, easy victim for everybody, easy to blame you. Easy to blame. And then what happened after that, after you had sex with her? I went back to my room. So you don't know what happened to her. That's what you are telling me, right? Yes, sir. Unfortunately for Jones, his story doesn't match the surveillance video. True, he's with his friend, they're talking to some other women. But the problem is, when you look at the surveillance video, when she leaves the hotel at 3:33 A.M., she walks out of the hotel and past these women and doesn't stop to talk to anybody. There wasn't any kind of an exchange between the two of them that would have been indicative at all of somebody soliciting a prostitute or a prostitute soliciting a John. And then he couldn't come up with explanations as to why'd you leave the hotel when you weren't supposed to? Jones literally stayed at the hotel another full day after the attack. The question is why would he be leaving the hotel at 5:28 in the morning, without checking out, carrying a big suitcase, only to return about an hour later without it. So he put his suitcase in the trunk of the car. But he never came back to get the suitcase. I took my Downstairs and put it in the trunk. I think I went to 7-eleven or something' for a soda. In the middle of the night? Not in the morning, when you are checking out? Because I am not even sure if I am gonna go to sleep. Despite the fact that they have his DNA, and he's given inconsistent statements, there are still real challenges in this case. He has got a story, and that is that their sex was consensual. She doesn't remember exactly what happened. I did not hurt her in any Kind of way. The key for investigators is going to be poking holes in his story. Even though he's calm and he's cool and he looks like he hasn't done a thing in the world, it was my job to be able to show that he's a liar. Brennan is now going in for the kill. He is focusing on that key moment, that tug of the suitcase when Jones was getting off the elevator. What stuff did you bring out to your car? Well, I had my suitcase. I said well, what was in the suitcase? What did you have in your bag when you went out to your car? My clothes. How much clothes did you have? Just a bunch of [ bleep }. I was there like three two weeks? I think? How much stuff? How big was your bag? When Brennan drills down on what exactly is in the suitcase, Jones actually pauses, which, the investigators know, they've now hit a nerve. You could just see the wheels turnin' and he's saying, oh, I gotta come up with a scenario. Why is this heavier than it appears to be? How heavy was it? Was it fairly light? No, it was heavy. I had a bunch -- I had my Xbox in there, all kinds of . Your Xbox was in there? All right, anything else? Your clothes? Clothes, books -- You had books? I said, you're an avid reader, you read all the time? He said, yeah. I said what kind of books do you like? What was the name of the books you were reading? I have no idea. I couldn't tell you what the name of the book was I just took out of my pocket. He reads all these books, but now this avid reader kind of has a case of amnesia. Everything you are saying doesn't add up. It doesn't make sense. What doesn't make sense? Your timeline stinks, your story stinks. The whole story stinks. There's no doubt in Brennan's mind that Jones is lying, and he's convinced that any jury that sees this video tape will believe the same thing. Because any of the things he was talking about made absolutely no sense whatsoever. Who goes and leaves, takes tir clothes out to the car before they check out? Nobody! Who's 6'4" 380 pounds, has some underwear and an Xbox in a suitcase and needs two hands to pull it out of a crack? Nobody! It doesn't make sense. It doesn't make sense, because it's all ! What is true is that he already beat this girl, he's dragging her out. He's gone for an hour, because he's looking for a place to dump her, because he thinks she's dead. Would you be willing to take a polygraph exam? Sure. Jones fails the polygraph test but he continues to maintain his innocence. So you don't know what happened to her, or how it happened to her? No. He played his role right to the very end. The bitter end. Michael Jones was charged with sexual battery and kidnapping. And before the case can even go to court, it almost falls apart. And the defense gets help from, of all people, the victim. It seemed like at this point, you have got a slam dunk case. But it wasn't. I was afraid this guy was just going to get let off, he was going to walk.
