The crash of Germanwings Flight 9525, headed from Barcelona, Spain, to Dusseldorf, Germany, left 150 people dead.
During their search, authorities took several objects and papers that may be evidence that will reveal more information on why Andreas Lubitz "deliberately" flew the plane into the mountainside, German police said.
Authorities searched the Lubitz family home in Montabaur and his apartment in Dusseldorf.
Other news sources have reported that Lubitz was depressed and that he had 18 months of psychiatric help for a 'serious depressive episode' while he was training.
