Giovanna Hernandez, 24, was stopped by local police while driving on Tuesday morning in her hometown of Leeds, near Birmingham, according to her brother, Dilan Hernandez. She was taken to a county jail and is now in U.S. Immigration and Customs Enforcement custody there, ICE’s detainee locator showed. Hernandez’s parents brought her to the U.S. from Mexico at age 7, her brother said. She was valedictorian of her high school class, has bachelor’s and master’s degrees in social work, and works with young people applying for college through a local non-profit organization, he said.
