Gilberto Guerrero Reyes, 61, was detained by ICE after being a passenger in a traffic stop in rural Texas on September 29. He was held on an immigration hold at a county jail before ICE took custody of him on October 1. His wife, Nivida, a cancer survivor who relies on an oxygen tank and daily medications, says Gilberto was the family's provider and her caregiver, and she is now facing emotional and financial hardship without him.
