MONTABAUR, Germany — The pastor of the Lutheran church in Andreas Lubitz’s hometown said Sunday that the community stands by him and his family, despite the blame prosecutors place on the 27-year-old co-pilot for causing the jetliner crash that killed 150 people in southern France. “For us, it makes it particularly difficult that the only victim from Montabaur is suspected to have caused this tragedy, this crash — although this has not been finally confirmed, but a lot is indicating that — and we have to face this,” pastor Michael Dietrich said. Authorities are trying to understand what made Lubitz lock his fellow pilot out of the cockpit and ignore his pleas to open the door before slamming the plane into a mountain on what should have been a routine flight from Barcelona to Duesseldorf. French officials refused to confirm or deny a partial transcript that German newspaper Bild am Sonntag said it had obtained of the cockpit recording. The paper reported Sunday that the pilot left for the toilet shortly before 10:30 a.m.
