The German hospital that was treating the Germanwings co-pilot for an undisclosed illness handed his medical records over Monday to prosecutors in the city of Dusseldorf, a clinic spokeswoman said.
Co-pilot Andreas Lubitz, 27, who is believed to have locked himself into the plane’s cockpit and intentionally slammed the aircraft into a mountainside in southern France, killing himself and 149 others on board last week, is the focus of the investigation.
The teaching hospital at Dusseldorf University refused to say Friday what his illness was, except that it was not depression. Lubitz was at the hospital on three occasions starting February, the last on March 10, for a diagnostic examination.
Prosecutors said the likelihood Lubitz struggled with psychological issues remains a central theory into his possible motive.
After searching his apartment in Dusseldorf, prosecutors said they found torn doctor’s notes giving him sick leave from work on the day of the flight.
Friday’s revelation that Lubitz concealed an illness from the airline, a Lufthansa subsidiary, prompted a call to amend German laws of doctor-patient privacy.
Meanwhile, Crews continued construction on a road that would ease access to the mountainside crash site Monday, as they searched for the contents of a second black box that could give investigators clues into the flight’s last moments.
They were also piecing together DNA evidence of hundreds of humans remains to identify victims, but Marseilles prosecutor Brice Robin told dpa that the DNA of the co-pilot had not yet been identified.
