On a cold, rainy night last November, Bastian Rodriguez spent the first hours of his 18th birthday inside an Immigration and Customs Enforcement van. Rodriguez was aging out of the Cowlitz County Youth Services Center, a juvenile jail in Longview, Wash., and was on his way to the Northwest ICE Processing Center, a privately run immigration detention facility for adults in Tacoma. He had already spent more than two years in ICE custody.
