article_snippet.sent: (CNN)The investigation into the crash of Germanwings Flight 9525 has not revealed evidence of the co-pilot Andreas Lubitz's motive, but the co-pilot Andreas Lubitz's motive suffered from suicidal tendencies at some point before the co-pilot Andreas Lubitz's motive aviation career, a spokesman for the prosecutor's office in Dusseldorf, Germany, said Monday.
article_snippet.sent: Investigators have not found any writings or conversations where Lubitz shared the co-pilot Andreas Lubitz's motive motives or confessed to any plans, prosecutor's spokesman Christoph Kumpa said.
article_snippet.sent: This was before the co-pilot Andreas Lubitz's motive ever got the co-pilot Andreas Lubitz's motive pilot's license, Kumpa said.
article_snippet.sent: Kumpa emphasized there's no evidence suggesting Lubitz was suicidal or acting aggressively before the crash of Germanwings Flight 9525.
article_snippet.sent: It is believed that Lubitz locked the captain out of the cockpit and deliberately crashed the plane Tuesday into the French Alps, killing all 150 on board.
article_snippet.sent: The speculation about Lubitz' mental state is based on a letter found in a waste bin in his Dusseldorf apartment.
article_snippet.sent: The note, which was "slashed," said Lubitz was not able to do Lubitz job, Kumpa said Friday.
article_snippet.sent: Lubitz to let Bild in.
