Chris D'Back (3:33)

From what I know, she would come over to Biloxi on the bus, sometimes with a friend, sometimes not. She'd usually stay a couple, couple days to a week. And from what her family tells me, sometimes it'd be up to three weeks. So wasn't anything unusual for her to be over here. But she always would call or keep in contact with a friend or something.

Ashley Flowers (3:54)

Except this time, Maidung was strangely quiet. Two weeks pass, then three, then four. But her family hadn't seen or heard from her. When they got a call from one of their mom's friends who had also been ghosted, they really began to worry because the woman said that Mai Dung was supposed to visit her after her Mississippi trip, but she just never showed. And she hadn't returned any of the woman's repeated phone calls either. The family decided they needed to take action. So on November 5, Mai Dung's son Vu Tran, decided that he needed to file a missing persons report with authorities in Escambia County, Florida, where they had lived. When he told him that his mom's last known location, though, was in Mississippi, well, you know how this works. Not their jurisdiction. So they called over to Biloxi where they got ahold of Dback. They explained the scenario to him and put him in touch with Maidung's family.

Chris D'Back (4:48)

One of the first things I did was call them to find out more about their mother and what she might have been doing here in Biloxi. Asked them the normal stuff, does she have bank accounts, you know, what's her cell phone number, who might she contact, who her friends were if she came over with a friend? I did ask them. We're talking about the end of September and this is beginning of November. Why they waited so long. They kind of reiterated that whole three week thing and it kind of made sense a little bit, you know, wasn't out of the ordinary. But once they started calling around, they couldn't get in touch with her. She usually would return calls, and if she wasn't returning calls, that's when they got concerned.

Ashley Flowers (5:28)

Now, when Maidung boarded the bus back in September, De BAC told us that she'd been alone, but that's not to say that she was planning to be alone the entire trip. Vu said that his mom was very friendly and, quote, would talk to anybody. And apparently she had been making these trips to Biloxi for at least the last year at that point. So it was likely that she knew people there. They just didn't know who those people might be. She'd never talked about anyone in particular. And tracking Maidung's movements, even in 2008, was going to be a challenge because there wasn't really a paper trail for De Bak to follow. Maidung only used cash, cash to gamble, cash to pay for her bus ticket, cash to pay for her hotel rooms. Vu said that his mom often kept large amounts of cash on her. She preferred to carry her money this way and actually didn't even have a credit card. She didn't even have a bank account.

Chris D'Back (6:21)

When you're tracking missing persons, that's one of the first things you look at, along with their cell phone. And so that was out the window.

Ashley Flowers (6:29)

So one of the first things that De Bak did was call Mai Dung's cell just like her kids had tried. But the same thing happened, no answer. He also called her long term partner, Quang Nguyen, whose number he had gotten from her kids. Maidung and Kwang lived together in Florida.

Chris D'Back (6:48)

Everybody I talked to asked about the boyfriend, was there problems there or anything like that. I said no, they got along real well. There wasn't anything that raises an eyebrow for anybody even checked into that background because, you know, certainly a domestic is one way to go, but, you know, was able to confirm he was at work and there was no past reports or any indication that there was an issue there.

Ashley Flowers (7:11)

When questioned, Kwang said that he was working offshore, as he often did as a fisherman. During Maidung's trip to the Biloxi casinos. It was only once he got back home in October that he discovered Mai Dung was nowhere to be found.

Chris D'Back (7:25)

Tried to call her, couldn't get ahold of her, went to the normal locations looking for her, couldn't find her, talk to the family and everything else. He also found out that the rent hadn't been paid. None of the other bills had been paid. About the end of the month, each month he would send her about $4,000 to pay rent, you know, buy groceries, things of that nature, live. And there was no indication that the $4,000 was left behind. So it must have gone with Ms. Tran when she came over.

Ashley Flowers (7:53)

Kwang told De Bak that Mai Dung had been talking about taking a trip home to Vietnam to visit her family. So DBACK immediately began checking airlines and reaching out to federal agencies that track international travel.

Chris D'Back (8:07)

And nothing. They used her maiden name, her current name, everything. It did not appear she left this country.

Ashley Flowers (8:17)

So with neither Maidung's partner nor her children knowing what happened in Biloxi, De Back was left to try to piece together Maidung's last movements on his own.

Chris D'Back (10:44)

I started contacting the different casinos to find out if she had a player's card, if she had ever stayed there, any information I could about her. So when you go to a casino, you can get a player's card. It's kind of like a member card for that casino. It's specific to each casino each and what you do is like if you're playing Slots or something like that, you can put your card in, it tracks your points, it just tracks your history. But the only two casinos that really had current activity around that time, the end of September 2008 to October 2008, was the Imperial palace in Beau Rivage.

Ashley Flowers (11:22)

Employees at the Imperial palace confirmed that Mai Dung had checked into the hotel on September 27th and paid with cash for a three day stay that she had booked in advance. Deeback was able to find activity on her player's card that first day, which would've been the 27th, and then again on September 29th and 30th.

Chris D'Back (11:41)

In all indications, she did stay from the 27th through the 30th. When we checked with the Imperial palace where we know she stayed at, nothing had been left in the room.

Ashley Flowers (11:50)

When de back called the other casino, the Beau Rivage, he found out that Maidung had also pre booked a room there from October 1st to the 3rd. But she never showed up to check in. And after the 30th, there was no more activity on her players cards at any casino in the area. Now, of course, it's possible that Maijung was still staying at the casino and playing games without swiping her card. But without any more activity to track, Deepak was stuck. None of the other hotels or casinos in the area had any record of Mai Dung staying or or playing around that time. The same was true for the local law enforcement agencies, hospitals, even the coroner's offices. None had any information about Mai Dung or any unidentified Asian woman who matched.

Chris D'Back (12:39)

Her description at the time. It was a little bit difficult there really didn't have a place to go search. Certainly the casinos did our best there with the assistance of surveillance and security. But other than that, we really had no place to go search.

Ashley Flowers (12:55)

You might be thinking, because I was too, that surveillance at casinos is pretty intense. Like hard for someone to go missing kind of intense. Casinos usually have not only high definition cameras covering every inch of the floor, but usually on the ground security teams constantly monitoring everyone and everything around them. The problem was that the surveillance cameras from the Biloxi casinos were where she would have been playing, only stored footage for around a week. And because Maidung wasn't reported missing until over a month after she was last in contact with anyone, most evidence of her movements in Biloxi had been deleted by the time Deeback got on the case. Now there was one piece of technology though that did still have data even over a month out, and that was Meidum's.

Chris D'Back (13:47)

It appears the Last time her phone was used was at 3 o'clock in the morning on October 4th. She called the phone. It went unanswered, so nobody was able to talk to her at that point. If she's the one making the call after that point, I can tell you there were several incoming calls but no answers. So I could tell that she didn't answer and I can tell that nobody ever made another call from her phone by looking at the 24 hours prior to that call to see who she called and you know, if they knew anything and you know, what was the reasoning for that call.

Ashley Flowers (14:20)

It turned out Maidung was in contact with a handful of people prior to her disappearance. De Bak tried to reach out to all of them. Most, it seemed, were friends that she would gamble with and many of them didn't answer. Now, to be exact, Maidung made 15 phone calls between 9.30pm and 3am on October 3rd and 4th, and none of those were picked up. Fourteen of these calls, including Mai Dung's last call, were to the same man. When De Bak called that number, the man said that he had met Mai Dung gambling on a previous trip and the two had sort of become friends.

Chris D'Back (14:58)

He said that usually when she would call it was hey, come, I'm in town, come gamble with me and all that. But he was working, didn't really have the time, so he just didn't answer the calls. That was one of the last calls that was made.

Ashley Flowers (15:09)

The last call she made that was answered was placed just before 9.30pm it was to a friend who we'll call Bob. And Bob told Doubt that during that conversation he made plans to meet up with Mai Dung at the Imperial palace that night, October 3rd. When Bob got there, he noticed Mai Dung had brought along a woman that he didn't recognize.

Chris D'Back (15:31)

Well, they hung out at the RP Casino for several hours and then they decided to go over to the Beau Rivage. They were at the Beau rivage, all the three of them, for another several hours. And around 4:00 on the 4th, May says, well, I'm going to go down to the Grand Casino and the gentleman gives her $5 for the cab. As far as the Grand Casino, we have no indication that she ever arrived through surveillance or players card. That's the last time she's seen. Sometimes you'll find where taxi companies keep the records at pickups drop offs. I couldn't find any pickup or drop off in the area for that time frame.

Ashley Flowers (16:08)

Doucheback doesn't know if someone called this supposed cab, or if it was already nearby or if it was really even a legitimate cab at all. To this day, he hasn't been able to pinpoint the company or the driver of that car. And it's after this 4am pickup that Maidung essentially goes off the grid. People continue to call her phone, but she never picks up again. Now, because Maidung's phone continued to get calls, it did continue to ping cell towers. Now, ordinarily, this could give investigators a general idea of the area where someone is, but not in this case, because the towers it was hitting on were kind of a red herring.

Chris D'Back (16:52)

I know she was at the border of IJ on the morning, but if you look at her phone records, she. It's hitting further north up in the county. It's a switch tower. So if the tower gets overloaded or something like that, it switches to another location. So the GPS location didn't help on the cell phone records.

Ashley Flowers (17:09)

De BAC was never able to locate Mai Dung's physical phone, but he was interested in learning more about Bob and that other woman that she was last seen with.

Chris D'Back (17:20)

When Bob met up with Ms. Tran at the IP Casino on the night of the 3rd, this unknown female was with her. Only thing he could tell me is that she was foreign. He didn't know where she was from, who she was, anything like that.

Ashley Flowers (17:33)

So Divac tried to see if the casino employees knew anything about this mystery woman, and that's when things sort of took a turn.

Chris D'Back (17:43)

None of them could tell me who this person was, but they thought she was involved in some kind of prostitution or something. I don't know how they got the idea she might even be involved in prostitution. Nobody ever came forward with any information for that. I would say I'm very skeptical of this unknown female. I know what people are saying and what they believe. I don't know how they. I want to say, assumed or what their theory is, where it came from, that she might have been involved in prostitution. I still haven't figured that one out, but if that is anywhere close to accurate, maybe she got hooked up with the wrong people, and maybe that's who she was staying with and something went wrong.

Ashley Flowers (18:24)

De Back tried to identify this woman, but other than searching for a player's card, which he couldn't find, there wasn't much he could do without surveillance or a paper trail. And we don't know how the mystery woman or Bob's nights ended after Mai Dung allegedly left. According to Doucheback, there was nothing to suggest that Bob was involved in Mai Dung's disappearance. And though all of the new information he provided was helpful, there were still tons, tons of gaps in the timeline. And honestly, even more questions.

Chris D'Back (18:56)

You know, she checks out IP on the 30th. Where did she stay between the 30th and the morning of the 4th? I can't even put her gambling at any of the casinos other than two days during that period, one being the last day and one being the one of the first days she's there. So I haven't been able to determine or figure out what she did in the middle there. It's just the story is so weird between those dates that she just, she wasn't at a casino or if she was, she wasn't using her player's card, she wasn't on any kind of video that we know of, and she wasn't checked into a hotel. So I don't know where she was staying at, who she was with. And majority of the time we get a report of a missing person, we find them a couple hours later, and you know, sometimes they're sitting at another casino, sometimes they just, you know, went to sleep or whatever it is. But. And thankfully, majority of Mr. Person reports, that's how they end up. They just lost track of time or whatever. Cell phone died, whatever it is.

Ashley Flowers (19:55)

By the end of November, Douchebag hadn't received so much as one tip from the public. It was starting to feel like there was nothing more he could do. But on December 5, just as he was on the verge of losing hope, De Bak got a call from a waitress at the Imperial Palace. She told him that just the day before, she had seen Maidung at the casino. And she wasn't alone. This message is sponsored by Greenlight. Looking ahead is important. It's important to teach kids important life skills like financial literacy. It's easy to do with greenlight.

That's greenlight.com thedeck to get started. The waitress who said she saw Mai Dung on December 4th told Doucheback that she recognized Mai Dung because she had served her at the casino many times before.

Chris D'Back (21:37)

She said, I think I saw her on December 4 with an unknown white male and never seen the guy before. Nothing. So I asked her, I said, well, where did you see her in the casino, exactly? And what was she doing? Did she appear to be scared, anything like that? She said, no, she appeared to be normal. I didn't go up and talk to her or anything like that, but I'm pretty sure it was her. So I started checking into that, checked her players records, got with surveillance to figure out exactly what camera she might be on, and they were never able to find anything. And so whether it was her or not, I couldn't tell you, but this employee felt like it was Ms. Tran.

Ashley Flowers (22:19)

DBAC said that he believed the waitress was reliable, so he had the Imperial palace look through their surveillance video based on her tip. But there didn't appear to be any footage of Mai Dung anywhere. So unable to confirm the waitress story, De Back had to assume she was mistaken. She couldn't say anything else about the man she'd allegedly saw Mai Dung with other than he was white. Which just left De BAC with another possible person of interest that he had no way to identify. That same month, De BAC also got a call from Mai Dung's son, Vu. He's the one who initially reported her missing. He told Doucheback that he received a call from somebody saying they saw Mai Dung at a casino in Lake Charles, Louisiana, which is over four hours from Biloxi.

Chris D'Back (23:08)

So I got with the Louisiana Gaming Commission, and between them, Mississippi Gaming Commission and casinos, we were able to check every casino nationally and put out a bolo, and there was nothing. New Orleans, Lake Charles, Las Vegas. Nothing on this Tran other than here in Biloxi.

Ashley Flowers (23:29)

Unfortunately, that was the last tip Doucheback received in this case. In fact, those two tips were the only tips he's ever gotten. In January of 2010, Deeback entered Vu's DNA into CODIS. And over the years, he's gotten a handful of hits for possible matches to unidentified remains found out of state. But each one was eventually ruled out.

Chris D'Back (23:52)

At this point, I can't say that there's a person of interest, but at the same time, you know, whether you want to call them witnesses or friends, associates, it just is an active missing person case. So it's kind of hard to rule anybody out at this point. But, no, there's no front running you know, person of interest, nothing like that. I'd love to talk to that driver. The unknown white female, and let's say December sighting was accurate. The unknown white male. Those would be the three people that I'd want to talk to right now, or anybody that knows where she may have been staying at between 30 September and 3 October.

Ashley Flowers (24:35)

Divac said that because it's been so long and Mai Dung hasn't resurfaced anywhere, gotten any tickets in another state or. Or popped up on any NCIC list, he can only assume that there was foul play involved in her disappearance. But other than that, he says he doesn't have enough information to come up with a theory about what happened to her. Here's our reporter Nicole, speaking with Detective D. Back. What would you say has been the most challenging part this case?

Chris D'Back (25:06)

The unknown, the inability to get information on those. The. Those few days in the middle of where exactly she was and what exactly she was doing, and not having the ability to go back and get the surveillance. A lot of the surveillance, most of it, as a matter of fact, because it's just gone. You know, we lost it in time. The records at the time, as far as the cell phone records, you know, certainly details are better nowadays than they were even in 2008. And not being able to pinpoint, you know, that cell phone ping where she was making the calls because it hit a switch tower. And then, unfortunately, majority of the calls she made in that last day went unanswered. So that, to me, that's the frustration. You just. There's nowhere to go to get the questions answered. And unless somebody comes forward that knows, you know, has those answers, there's no technology we could use to get it, no records we can go dig up. We haven't received any new leads, any new information in over a decade now. And the few attempts or times that I've been able to pull it out and look at it and try to rerun the information, trying to find a new connection, I've gotten nowhere. I think anything is important, especially we're talking about the time frame. Again, through the end of September. I stayed through the beginning of October. But if she was observed or seen after that, that information is important, too. So it doesn't matter how small it is or insignificant you believe it is. You know, any information can help. And it's a puzzle. You're trying to put the puzzle together, and you may have that piece, whether it's very valuable or it's not as significant. It's still part of the puzzle.

Ashley Flowers (27:01)

Today. Mai dung would be 67 years old. @ the time of her disappearance. She was 5ft tall and 140 pounds. She had black hair, brown eyes and pierced ears. You can find her photo in the show notes.
