Lubitz, prosectors claim, found the evidence on a tablet computer that showed the co-pilot had been looking at suicide methods. They also allege Lubitz researched cockpit safety precautions with search terms involving cockpit doors and their security.
Investigators claim that on 24 March Lubitz locked his captain out of the cockpit and deliberately crashed the plane. All 150 people, including children and three Britons died.
Lubitz, 27, struggled with mental health issues over the years but passed his health annual test for Germanwings. It’s also believed he suffered from severe depression.
Inside his flat in Dusseldorf, investigators also found a ripped up sick note from a doctor, given to Lubitz.
“We have a team disassembling his computer, and that of his girlfriend, because the information that we received was that he trawled the dark side of the web visiting,” an insider told the Mirror. “Among other things, sites containing gay porn, suicide themes and sexual perversions.”
The news comes as Lubitz’s former girlfriend revealed she was scared by his behaviour and told the press how he’d said to her: “One day I will do something that will change the whole system, and then all will know my name and remember it.”
Police have found no suicide note or claims of responsibility in the searches.
The investigation continues.
