Ulises Peña López and his attorneys sued the United States government and private prison operators GeoGroup and CoreCivic in federal court, alleging violations of the Rehabilitation Act after his detention by U.S. Immigration and Customs Enforcement in February 2025 in Sunnyvale, California. The complaint states that ICE officers took López to an alleyway and struck him until he lost consciousness, requiring CPR, and that he endured inadequate medical care and verbal abuse while housed at facilities operated by GeoGroup and CoreCivic. His wife and young daughter witnessed part of the alleged beating. The lawsuit says that López, a carpenter who suffered a mini‑stroke in August 2024, experienced worsening headaches, right‑side weakness, numbness, eye pain, hearing loss, insomnia, nightmares, blurry vision, back pain and difficulty walking during his eight months in detention. He was unable to work and did not receive timely medication. Staff allegedly mocked his disability and made statements such as “motherfucker, you don’t get to be asleep” and “you’re never gonna walk again.” At the transfer to California City Detention Center in August 2025, the complaint alleges staff denied timely medication and subjected him to harsh conditions. CoreCivic’s spokesperson said the company’s top priority is the safety, health and well‑being of detainees but declined to comment on the litigation. ICE declined to respond to a request for comment. Elena Hodges, co‑director of Pangea Legal Services, said the case seeks accountability for physical and emotional harms and aims to signal that ICE and private prison contractors are not above the law. After publication, an ICE spokesperson said claims of substandard medical care are false and that staff always use the minimum amount of force to safely de‑escalate situations.
