look real at all. >> Putting them here, they're super light. Super light. But that we take a look at them every day and make sure they're out of weight. >> We see this a lot. People trying to use project altered documents. You know, it's just with our training. [music] We do recognize things that are out of the ordinary. Counterfeit visas can be bought for thousands of dollars in Mexico, making serious money for criminal gangs. But this woman is insisting that hers is genuine. The woman claims she applied for her visa in person at the US embassy and it was later posted to her, but officers are convinced she's lying. Foreign speech. Foreign speech. So far, she's saying that she got the document, but the counsel, but she can't tell you where the pamphlet is, where she picked them up. Like, she's just kind of stalled. >> With the woman refusing to admit to her crime, officers decide to take her fingerprints. Checking them against their records will prove whether or not her visa is valid. nothing. But the fingerprints did show she did try to apply for a visa in 2018, which was denied. >> The woman did once apply for a visa, but her application was denied. Officers must now decide what penalty she will face. >> This is an immigration crime because she's presenting fraudulent documents to come into the United [music] States. >> The woman could be prosecuted and even jailed. Back at the Wararez Lincoln Bridge, >> there's an anomaly that we need to check is in the backseat area. >> Following a tip off, officers have discovered packages hidden in the backseat of a car, which they suspect could contain the deadly opioid fentinyl. There is an increase of importation of fentanyl by the smuggling organizations and we're very careful now with every single seizure. It's very dangerous not just of course for the the consumer but also uh for the officers that are trying to find it very small. >> What's up Charlotte? How you doing? How's it going? What's up air? How you doing? Thanks. amount of fentanyl can kill a lot of people. >> Just 2 milligrams of fentanyl is considered a fatal dose and inhaling even the dust can put officers at risk. >> I'm just watching this border border control or whatever show. I don't watch this show in a minute. I used to watch this all the time. The first packet is carefully opened revealing multiple layers. Electrical tape. >> Cellophane. And then it's vacuum sealed. >> Vacuum seal. >> And it's got toothpaste. >> Yeah. >> Toothpaste. >> Toothpaste has been used to try to mask the smell [music] and throw off the bridg's canines. now to find out for certain whether it is the cartel's most prized commodity that officers have intercepted. The [music] substance is tested. As you can see, it's a delicate process and we got to be very careful. So, we do it in this particular plexiglass case uh to avoid contamination in the area. >> The officer's Gemini laser detection system can identify all the major narcotics and should [music] produce a result in just a few seconds. As [music] suspected, the substance is fentinyl, the drug that's fueling a nationwide opioid crisis. It's responsible for a growing number of overdoses [music] with other recreational drugs often contaminated. Fenol is being used as a cutting agent to a lot of other drugs that are also very dangerous already. Fenol can be found in in cocaine uh sometimes even in meth to um increase the value and the the product itself right of what they have. They can make one kilo of cocaine maybe into two by adding fentanyl. And of course it's a lot more addictive and a lot stronger. Every fentinel seizure at the bridges is big news and must be thoroughly investigated. >> The process is to uh collect as much information surrounding the seizure and from there this information is also going to be provided to the investigative agency so they can further the investigation. >> This case will be dealt with by the DEA. Officers meticulously gather as much evidence as they can to hand over. So right now what they're trying to identify is to see if it has a stamp. Um, every smuggler has their own stamp. So that's what we're trying to figure out what it is so we can track it. >> This time the stamp is embossed onto the brick of narcotic. >> It says tomato in Spanish. So you can see the actual tomato here and the O has the leaves on the top. So again, this is um sort of a for them to track their own merchandise. [music] >> The packets are also dusted for fingerprints. And once the evidence gathering is complete, the narcotic is weighed. >> 12 bundles, 13 flat. >> 12 bundles, 13 flat. So total weight of the narcotics depending on for synthetic narcotics is u 13 kilos 12 bundles of 13 kilos very exact if um I mean usually that is the case a lot of these smugglers I mean they just send the amount that they pay for >> a single kilogram of fentinum has the potential to kill 500,000 people >> street value of more than $130,000 >> very cheap to get it in Mexico but once it it crosses a river or it crosses the international border, it starts multiplying in value. So any city in the east coast, the west coast that that receives this type of product, the of course the value will multiply several times. >> In total, this shipment is worth $1.7 million. Its interception is a major blow to the cartel responsible. As for their courier, he can expect [music] to spend years behind bars. But by taking um these 13 kilos off the streets, we were able to probably save numerous lives. And um this is very important for us. I mean, trying to do this job here and trying to take these type of narcotics that are very harmful to society off the streets. [music] 180 mi further down river is the Texan city of Progresso. >> Okay, I got that. That's all I >> linked by bridge to Novo Progresso in Mexico. Here, officers are on the lookout for travelers carrying illegal medication into the US. And they know all too well that smugglers come in all shapes and sizes. >> Purpose of Mexico today? >> What are you bringing back from Mexico, ma'am? >> This morning, two sisters in their 70s have been referred for an inspection after an X-ray picked [music] up something suspicious in their luggage. >> Been arrested before in the US or anything, ma'am. >> Officer Zavala is not swayed by their gental demeanor. >> I have two sisters. that have been referred for an enforcement inspection. They appear to be nice senior citizen ladies, but we've seen many just like them that have smuggled before. >> The X-ray detected what appears to be loose pills hidden inside the lining of one of their bags. >> She knows she has something. I'm not going to entertain the lady. I want to know what is it that you have. We're serious. It's a busy day, so I'm not going to be doing no scavenger hunts. I know something's there. >> Same. It's going to be very straightforward, okay? I don't want to waste your time and we're not going to waste ours. This is your purse. Do you understand that? Inside your purse, it was discover. I need to find out where how did you put them in there? Is it necessary for me to get scissors and I don't know, but I'm not going to do that. I come and show how secretly put it in there. I can't do that. The woman has admitted putting pills through a hole she's made in the lining. >> And that's okay, ma'am. I totally understand. I'm not a medical doctor, but the way you're bringing it in is not >> The pills are Tramodol, an addictive painkiller that is only available on prescription in the US. >> How many bottles did you put in there, ma'am? I want to say three or four. It's either 50 more or 6. How many bottles did she double pack? This is four. So you have four bottles in this small and it's a huge number. >> In small quantities, Tramodol can be legally imported into the US if declared, but this woman has more than 200 pills. The issue here now is the way you are smuggling it into the United States. That is a schedule 42 substance. You do understand that, right? I'm sure you do. You look like a very knowledgeable agent, so I'm sure you know what I'm talking about. >> Deliberately smuggling a schedule 4 controlled substance is a felony offense, punishable with up to 5 years in prison. Are you doing the same strategy? >> Because they're traveling together. Officer Zavala suspects that the [music] elder sister could also be smuggling. >> I'm asking you before I search your purse. Are you doing the same strategy? Yes, sir. >> Yes. >> Back in Hidalgo. Officers are continuing to question a woman who's been caught trying to use fake visas [music] to enter the US with her son. still claiming the documents are genuine. But a search of her bag has uncovered more incriminating evidence. What's up? What's up? >> Found a travel permit called an I94, which is only issued at the border. Good. That's good. >> Most Mexican nationals traveling inside the US require an I94 as well as a valid visa. >> They had it hidden in in their backpacks. So, we went in there and we found it. >> We're the ones that issued these. Only us. Nobody else. Only us. [music] >> What's more, these supposed I 94s are [snorts] riddled with errors. There's so many discrepancies everywhere. >> Admit it, for example, only has one T. It's supposed to have two T's. December is D E C and they put D I see. It's in Spanish. He's trying to put it in Spanish. >> With not just two, but four forged documents in her possession. Evidence of the woman's wrongdoing is mounting. >> This is supposed to be a formal document. Obviously, it's it's it's a counterpart. It's it's fake. Officer Gonzalez hears back from the prosecutors. >> I just got word from the supervisor. We are going to expedite remove her. She's going to have a 5-year ban. We're going to go ahead and take her across the street so we can process her and that way we can return her to Mexico. >> Having narrowly escaped jail time. The woman and her son will be escorted [music] to the other side of the border. She'll be banned from entering the US for 5 years. [music] Once that time's up, she can make another attempt to apply for a genuine visa >> in Progresso. >> So, you have four bottles in this. >> I couldn't sleep. >> The 75year-old woman's been >> I'm kind of sleepy. I just woke up from my nap. Might need to sleep a little more. I think I'm going to wake up in a second here. I just drank some caffeine. Super Bowl Cindy. And what a game. What a game it was, man. If you like highscoring contests where the outcome is in doubt to the finals. >> Okay, let's play a game. Um. [sighs] Yeah. Okay. >> [snorts] >> Okay, I'm going to [snorts] go I'm going to I'm going to make thumbnail for this uh game and then I'll play the game for a couple hours. I'm going to clean up and stuff. [clears throat and snorts] See What's up? Uhel, [snorts] how you doing? [sighs] What's up? What's up? Uh, Tia, right? How you doing? >> [sighs] [snorts]
