Drugs are found all the time on or with people trying to cross the border. Our Lauren Kendrick got an inside look at how CBP catches people with drugs. Within the last few weeks, CBP has made large seizures of drugs. Most of them were found on buses. We spoke to someone with CBP about how they find those drugs. "There is no template for who may be attempting to bring in narcotics." Chief officer Davolina tells us the agents at the bridge have seen everyone from babies to little old ladies attempting to smuggle in drugs. The officers decide who to question . "Upon their discretion, they can send in people to be examined a little bit closer and this is how our officers have been able to encounter the success they've had." Success they've had in the last two weeks. "Bringing in seizures of heroin, marijuana. More than a thousand pounds. heroin more than 122 pounds." Davolina says the last five seizures have dealt with bus passengers. Most recently, a bus was carrying 123 pounds of heroin in the floorboard of a bus worth twelve million dollars. "That is one of the largest heroin seizures we have seen in the last few years." The twelve million dollars worth of heroin seized last week was done so by this x-ray truck right behind me. Currently, there is an x-ray truck, which drives next to the buses to spot drugs. This will soon change and be replaced by the z-portal, where vehicles just drive thru it. With this advancement, speed and efficiency will exist for drug seizures.
