A coalition of 36 lawmakers, including Senator Elizabeth Warren, has expressed grave concerns about the Immigration and Customs Enforcement's (ICE) online detainee locator system (ODLS), which they claim has led to 'disappearances' of individuals detained by immigration authorities. In a letter to the Department of Homeland Security (DHS) inspector general's office, the lawmakers highlight that the system has become 'increasingly unreliable' since January 2025, making it difficult for family members, attorneys, and journalists to track detainees. They cite specific cases, such as that of Any Lopez Belloza, a 19-year-old college student who was deported before her location was updated in the ODLS, as evidence of the system's failures. The lawmakers are urging an investigation into the systemic failures contributing to the issues with the ODLS, which has been in place since 2010. They point to the high number of detainees, currently exceeding 70,000, and the use of non-traditional detention facilities as factors exacerbating the situation. The letter also raises concerns about the lack of oversight at these facilities and the rapid transfers of detainees, which further complicate tracking efforts. As the Trump administration continues its aggressive immigration policies, the lawmakers are demanding accountability and transparency from ICE and the DHS.
