Transcript for Investigator tries to ID person of interest on hotel surveillance: Part 5
Battery charging. ��������� When Ken Brennan posed this idea that Inna had been attacked by this large man that we see on the surveillance tape, wheeled out of the hotel in a suitcase and dumped, detective Foote thought this was a joke. Thinking that maybe he is a little out there? Sometimes we are all out there, but it's a lead. It's not on my priority, I am putting this lead off to the side, while I pursue the leads that I have. Actually he said that's a nice theory, good luck with it, let me know when you get any further. Ken is persistent and, you know, he went after that lead. He is determined. He is determined. This is a pretty bizarre theory, how does this go over with the hotel? In fact, one of the owners said, what the hell kind of an investigator are you? He goes, you're telling me it's this big black guy, everybody else says it's two white, hispanic. Where's this coming from? You know? And they all started laughing. And that's what really pissed me off. And I said, hell or high water, I'm going to find out. I'm going to prove to these people that I'm right. I knew this was the guy. And I was going to catch this guy. The case is pretty cold at this point, he's long gone. How do you even begin to try to find this guy? You know, I didn't know if he was somebody that was staying at the hotel, that was a visitor that was just visiting. If it's a guy just walked off the street. We didn't know, so that was the next part of the investigation. Like so many hotels, this one actually photocopied ids of registered guests. But you can see the pictures are barely recognizable, and weren't even useful. So you go back to the tape? So I go back to the tape. And what do you find? I was looking to see if he had any interaction with any of the other people at the hotel. And he does. He ends up interacting with another fellow. The big question now is who is this second man that they see on the videotape? Well, Brennan, being the eagle eye that he is, notices right away that the man is wearing a lanyard around his neck. Could that help them pinpoint where this guy might've worked? I'm trying to find out why he's wearing this name tag. Problem is that they can't read it. The video simply isn't good enough to allow them to see what the name is on that lanyard. One of the problems with surveillance cameras are that they many times are not totally crystal clear. So, for example, if you have names on a nameplate, you may only capture part of it. And then fortunately, that's where Brennan is at this point. He has partial words but he doesn't know exactly what they mean. He even went to nasa to see if they had ways of magnifying images that would tell him what was on that I.D. Badge. I say, listen, you know, I know you guys look at digital photography from light years away, maybe you could help me out on this case that I'm working. So they couldn't, they couldn't do it? No. So, they informed me, listen, we tried, but we're not able to get that for you, so -- I said, "Okay, fine, let's go back to the tape." Later on in the video, when he's out by the hallway, you can clearly see that this says Mercury. But it's -- What's -- what's Mercury? That was the problem, I didn't know. Could be anything. On the back of his shirt you could make out barely a V and an O. And for whatever reason, I don't know, I think that says verado. What the hell's a verado? I said, "I don't know, let's find out." So then I went online and did a and I got a hit. And it showed that Mercury marine made a brand new outboard engine, by the name of verado. After I saw that, and I realized that was a boat engine, I said, these guys are working at the boat show. He discovered that in fact this big boat show had been going on at the same time that this crime occurred. And then they learned that mercwas a major exhibitor during the boat show. Brennan is convinced that he's just about to close this case. He assumes that the guy he's looking at works with this other guy that he's seen on the tape at Mercury. And so now the only thing he's gotta do is figure out who he is. Ken would text me or send me emails of everything he is doing and he tells me about the t-shirt and the verado. And at this point, I am giving him the thumbs up, good job. Mercury marine is actually, the parent company is a company by the name of Brunswick. I ended up contacting Brunswick, speaking to the head of security, and id, listen, do you have any employees that stayed at the airport regency hotel. He said, "No, we didn't." So it's a dead end? So, it's a little bit of a set back. I said, well, trust me, one of the guys there is walking around with one of those Mercury verado shirts, somebody was giving them out. So, he goes, "Okay, let me get back to you." So I said, "Okay, fine." Couple days later he calls me back, he says, "Far as we can tell, the only people that received any of the verado shirts were employees that worked at the food court." So another connection? So there's another connection. I said, well, let's find out who's the caterer for the Miami boat show. So, it ends up becoming a company called center plate. So I end up contacting center plate. And they told me, "Listen, we'd love to be able to help, but we hire people from all over the country. We wouldn't be able to tell you where these people stayed no matter what." They told him that they do reimburse people for housing. But they have no idea where they might stay. They simply don't have that kind of detail. These are people who are coming in, doing contract work. And when it comes to the hotel, it's up to them where they stay. They can't say who stayed at the regency airport hotel. So now, he's hit another dead end. But I've come a long way, and I said I'm not going to give up on this guy yet. I said, "Listen, he's really distinctive. The guy's about 6'4". He's a black fella, and he wears glasses." So I said, "Does anybody remember working with a guy that matches that description?" Sure enough, about a week or so later, he says, nobody knows the guy's name, but one of the people that remembered seeing this fellow, remembers something about him being hired out of Louisiana. He believes that's where he's from. So now you've gone from Miami to Louisiana? So now I'm over in Louisiana. Brennan's search is now taking a big turn to the big easy. Trying to find somebody in New Orleans is kind of like finding a needle in a haystack. There's no way 50i78 going to let this guy go.
