Report: Germanwings co-pilot was being treated for depression
A person familiar with the investigation told the Journal that Lubitz was not only being treated for depression, but also hid news of his treatment from his employer - Lufthansa's low cost subsidiary Germanwings.
Investigators believe Lubitz locked the flight's captain out of the cockpit as the 28-year old junior co-pilot flew the Airbus A320 airliner into a mountainside.
According to the Wall Street Journal source, there is no evidence that would indicate Mr. Lubitz was on any "mind-altering medication" at the time of the incident.
Lubitz reportedly ripped up medical leave notes that had been issued to him and according to Germanwings were not submitted to the airline.
