Massachusetts senators demand investigation into ICE detainee system

BOSTON (WWLP) – A group of senators, including Massachusetts’ Elizabeth Warren, is leading 32 members of Congress in pressing DHS to investigate ICE.

U.S. Sen. Elizabeth Warren (D-Massachusetts) and U.S. Sen. Ben Ray Luján (D-New Mexico), along with U.S. Rep. Veronica Escobar (D-Texas) and U.S. Rep. Lauren Underwood (D-Illinois), led 32 other members of Congress in urging the Department of Homeland Security Inspector General to investigate failures in the Immigration and Customs Enforcement’s (ICE) detainee locator system. The lawmakers contend that without a functional system, the DHS is effectively causing “disappearances” on U.S. soil.

The group of lawmakers requested an evaluation of the Online Detainee Locator System (ODLS), citing reports of inaccuracies that hinder legal representation and increase the risk of deportations.

The DHS Online Detainee Locator System allows the public to determine if a person is in ICE custody and their location. ICE policy mandates updating the ODLS within 8 hours of a person’s arrival at a facility. However, reports indicate individuals are not being accurately added for days and sometimes weeks, with increasing inaccuracy noted since January 2025.

The failure of the ODLS impacts detainees’ ability to obtain legal representation. Attorneys have reported difficulties filing habeas petitions due to unknown client locations, leading to an increased risk of detainees missing court hearings or case deadlines.

Families have also experienced distress, with some reporting that their loved ones were deported before their location was ever recorded in the system. Massachusetts resident Any Lopez Belloza was deported under such circumstances.

The current scale of detention exacerbates the ODLS issues. There are more than 70,000 people in ICE custody, an 80% increase since December 2024. The Trump administration is detaining people at an unprecedented scale, according to the lawmakers.

Frequent transfers of detainees make ODLS updates more challenging. Matters are further complicated by individuals being held in unconventional settings, including military bases, state-run facilities like “Alligator Alcatraz,” ICE field offices and, soon, warehouses built for storing packages.

Some experts expressed concerns that these issues could be intentional, used by ICE to remove people from jurisdictions with more protective laws or favorable judges. One ICE agent reportedly told a detainee being transferred from California to Indiana that it was “thanks to the laws in California.”

In their letter, the lawmakers formally requested the DHS Inspector General to address several points to understand the scope of the problem. They specifically asked for information on why the ODLS system has reduced its timeliness, the types of information ICE does not add to the system and the practices ICE employs for updating location information.

The lawmakers concluded their letter by requesting that the DHS Office of Inspector General conduct an evaluation of the matter to understand the problem’s full scope, the reasons for reporting gaps and the impacts on detainees and their families.
