German prosecutors concluded co-pilot Andreas Lubitz was suicidal when he locked the captain out of the cockpit and flew a Germanwings plane into the French Alps in 2015, killing all 150 people on board. But on the second anniversary of the crash, Lubitz's father is floating a new theory. At a press conference Friday, Guenter Lubitz said his son had suffered from depression in 2009 but "loved life" at the time of the crash and "had no reason to plan and carry out a suicide," per the BBC. To the dismay of victims' families, Lubitz, 63, instead argued his 27-year-old son was incapacitated by a carbon monoxide leak in the cockpit of the plane while the captain was locked out.
Prosecutors agree Andreas Lubitz hadn't been recently diagnosed with depression, but they say he suffered from a "psychological illness" months before the crash and was likely taking anti-depressants, per the AP. That's not enough to convince journalist Tim van Beveren, who spoke at the press conference alongside the elder Lubitz. He accused prosecutors of "poisoning" the investigation from the beginning by failing to pursue other possible leads into the cause of the crash. He also questioned the plane's airworthiness certificate, reports Deutsche Welle. A lawyer representing victims' families says they were left "shocked" and "literally speechless" by Friday's "irresponsible" display, per Euronews. (Read more Germanwings crash stories.)
