Agents with Immigration and Customs Enforcement (ICE) busted stash houses in houses in an affluent Washington, D.C., neighborhood, where dozens of illegal aliens were allegedly concealed, according to NBC News.

ICE Homeland Security Investigations (HSI) authorities found 73 migrants, including 60 adults and 13 children, in northwest Washington homes in an area where the median home price is $750,000, NBC News reported, citing internal documents.

An HSI spokesperson told the Daily Caller News Foundation declined to comment on the investigation.

“Our goal is to identify, disrupt, and dismantle significant Transnational Criminal Organizations (TCO) involved in human smuggling through the aggressive, and smart, application of the full range of our authorities. In April, DHS committed more than $50 million to bring the swift hand of justice down on these criminal organizations,” the spokesperson told the DCNF.

Stash houses, which are mostly found at the southern border and are run by human smugglers, are often overcrowded and filthy. HSI has recorded 2,266 cases, 4,264 criminal arrests, 1,495 indictments, 1,334 convictions and 6,556 Admin Arrests, all related to human smuggling, in fiscal year 2021, according to agency data shared with the DCNF.

Illegal immigration at the U.S.-Mexico border has surged since President Joe Biden took office in January 2021, with border authorities encountering over three million migrants while the administration has been in leadership, according to U.S. Customs and Border Protection (CBP).
