DSS special agents serving as assistant regional security officer-investigators (ARSO-Is) are at the frontline of conducting transnational investigations and collaborative training with DSS international and foreign partners. These law enforcement officers work to protect U.S. national and border security before threats reach U.S. shores.

As it does each year, the Diplomatic Security Service (DSS) punched above its weight in 2019 especially in the areas of overseas investigations and training.

Here is a snapshot of one of their cases in 2019:

Given its sustained presence at more than 270 U.S. missions around the world, DSS can uncover criminal networks in even the most remote locations. In 2019, the ARSO-I at the U.S. Embassy in Lima, Peru, traveled several hours to a small, remote city in Peru to train and build relationships with local law enforcement and immigration officials. The training paid off, as one of the trained officials shortly thereafter identified an imposter using a stolen U.S. passport. That tip turned into a full investigation in which ARSO-I Lima and the embassy’s vetted police unit uncovered an international human smuggling and trafficking network. The team quickly shut down the network, and the Peruvian National Police arrested the ringleaders. ARSO-I Lima continues to train and engage with Peruvian counterparts to disrupt transnational crime, no matter the distance.
