French prosecutor OKs burials for 150 victims of Germanwings crash after all remains ID'd

The remains of all 150 victims of the Germanwings plane crash in the French Alps will finally be turned over to their families for burial now that investigators say they have completed their identification process.

The Marseille prosecutor says Tuesday that death certificates for everyone aboard the doomed Airbus A320 jet have been signed and turned over to officials at German airline Lufthansa, parent company of the low-cost airline whose co-pilot intentionally crashed the aircraft into a mountain.

Authorities are still puzzling over why co-pilot Andreas Lubitz, who had suffered from suicidal tendencies and depression in the past, locked the captain out of the plane's cockpit on March 24 and sent the Airbus hurtling into a mountain, killing all 150 people on board.
