The co-pilot of the Germanwings airplane which crashed last week killing all 150 on board, searched the internet for information about committing suicide and the cockpit doors, days before the crash, investigators said Thursday.

The details were found in Andreas Lubitz’s iPad, found at his apartment in Dusseldorf, Germany. He conducted the searches between March 16 and March 23, the day before the crash.

“During this time the user was searching for medical treatments, as well as informing himself about ways and possibilities of killing himself,” the investigators said in a statement.

“On at least one day the person concerned also spent several minutes looking up search terms about cockpit doors and their safety measures,” the statement said.

Investigators believe Mr. Lubitz, the co-pilot, deliberately crashed Flight 9525 on March 24 after locking himself in the cockpit, and stopping the captain from entering.

The plane was travelling from Barcelona to Dusseldorf.

The latest disclosure came as investigators in France reported finding the second black box from the crash.
Prosecutors in Düsseldorf declined to release any information on the exact terms Mr. Lubitz searched for, the New York Times reported.
