The Department of Homeland Security will start a DNA testing pilot program next week to help identify and prosecute individuals posing as families in an effort to target human smuggling, two department officials confirmed to CNN.
The Rapid DNA testing, as it's known, involves a cheek swab and can, on average, provide results in about 90 minutes, a senior Immigration and Customs Enforcement official said.
The pilot program will run for two to three days in two border locations, the official added.
It's the latest move by the Trump administration to address the swell of migrants, predominantly families and children from Central American countries, at the border using a wide variety of technology and increased resources to fight illegal immigration.
DHS has repeatedly warned that children are being exploited by traffickers to skirt the nation's immigration laws. Currently, the government can't hold migrant children in detention for more than 20 days, often leading to the release of families — or groups posing as families — until their immigration court hearing, a practice President Donald Trump has derided as "catch and release."
The information collected in the DNA test will not be stored or shared, the ICE official said.
"This is part of a larger investigative process. This is not screenings, this is not just random application of this, this is a pilot designed to assess the usefulness of this technology in an investigative process," said ICE acting Deputy Director Derek Benner, calling it "new ground" for the department.
DHS press secretary Tyler Houlton also confirmed the pilot program.
According to DHS, there was a 315% increase "in the number of cases of adults with minors fraudulently posing as 'family units' to gain entry" from October 2017 to February 2018.
"Cases of 'fake families' are popping up everywhere. And children are being used as pawns," former Homeland Secretary Secretary Kirstjen Nielsen in a speech last month. She also said DHS had uncovered "child recycling rings," a process of using children repeatedly in an attempt to released in the US.
Both ICE and Customs and Border Protection — two agencies within DHS that handle the processing of migrants — will be involved in the pilot. CBP will make a referral for investigation and ICE Homeland Security Investigations will take it from there, the senior official said.
