ATHENS, Greece (AP) — The Latest on the flow of migrants in Europe (all times local): 12 p.m. A district court in Germany has opened a trial against a migrant accused of raping and killing a 19-year-old female medical student in the southwestern city of Freiburg last year, in a case that fueled a nationwide debate about the country's migration policy. The trial started Tuesday for asylum-seeker Hussein K. in Freiburg. The victim vanished in mid-October on her way home in Freiburg. Her body was found in a river. The suspect was linked to the crime through DNA evidence and video footage from near the scene. The suspect arrived in Germany in 2015 without identity papers.
