Diana Sanchez, a Stockton-area resident with pending asylum and U-visa applications, was detained by ICE officers at a check-in appointment in mid-December 2025 at Otay Mesa Detention Center. During her nearly four-month detention, she witnessed multiple medical emergencies including strokes and fainting, reported inadequate medical response and poor food quality, and experienced retaliation from guards after filing grievances about treatment. A federal judge ruled in her favor in April 2026, finding ICE lacked authority to detain her, and she was released.
