Sandra Castaneda was 20 when she was given a life sentence for a murder she didn’t commit. After she’d spent 19 years in prison, a judge overturned her conviction and ordered her release. But instead of walking free, she found herself behind bars again, in a holding cell in an Immigration and Customs Enforcement (ICE) office. That’s because California prisons notify ICE whenever they release a person who wasn’t born in the U.S. – even someone like Sandra who’s a legal permanent resident who’s lived here since she was a child. What happened next is a window into an all-too-common story for immigrants who get funneled from the criminal justice system into the deportation system. Even when states like California have overturned their convictions. KQED’s Senior Immigration editor Tyche Hendricks has been following Sandra’s case for months, and brings us her story.
