German authorities said on Friday they had found torn-up sick notes showing that the pilot who crashed a plane into the French Alps was suffering from an illness that should have grounded him on the day of the tragedy.
French prosecutors believe Andreas Lubitz, 27, locked himself alone in the cockpit of the Germanwings Airbus A320 on Tuesday and deliberately steered it into a mountain, killing all 150 people on board.
"Documents with medical contents were confiscated that point towards an existing illness and corresponding treatment by doctors," said the prosecutors' office in Duesseldorf, where the co-pilot lived and where the doomed flight from Barcelona was heading.
Torn-up doctor's notes found in his home would have excused Lubitz from work for medical reasons, for a period that included the day of the crash. That supported the view that Lubitz had "hidden his illness from his employer and his colleagues", the prosecutors said.
They found no suicide note or confession, "nor was there any evidence of a political or religious background to what happened", they added.
Germanwings said Lubitz had not submitted any sick note that would have grounded him on Tuesday, March 24, the day of the crash.
In France, authorities said they had recovered between 400 and 600 body parts strewn across the Alpine crash site. No bodies were found intact and DNA testing would be the best way to identify the remains, Patrick Touron, deputy head of the criminal research division of France's Gendarmerie, told reporters at the site. Investigators would look for pieces of uniform to try to identify the crew including Lubitz.
Lubitz's mental health - and what Germanwings and parent company Lufthansa knew about it - could become central questions in any future legal case over the crash. Under German law, employees are required to inform their employers immediately if they are unable to work.
