German investigators announced Friday that Andreas Lubitz, the co-pilot of the doomed Germanwings plane, had intentionally hidden his medical condition from his employer. The news comes after a report that Lubitz had spent more than a year receiving psychiatric treatment after suffering from a "serious depressive episode."
Investigators searched Lubitz's home and found a ripped-up doctor's note that authorized Lubitz to take time off from work due to an illness. The investigators added that they did not find "any indication of a political or religious" nature in the home, nor did they find a suicide note.
The investigators are looking into Lubitz's family background as well as a potential history of psychological problems, including depression.
Lubitz is believed to have intentionally crashed a Germanwings plane in the French Alps on Tuesday, killing all 150 people on board.
