Germanwings Crash Updates: Did Killer co-pilot 'spiked coffee of his captain with diuretic drug?

After the revelation of the cause of the Germanwings Plane crash, more development has been unfolding as to what and what the killer co-pilot must have done, undergo or research before carrying out the plane crash.

According to the new development on the investigation and report by UK Daily Mail, Air crash investigators examine a computer belonging to Germanwings co-pilot Andreas Lubitz in a bit to try to determine whether the killer 'spiked' his captain's drink to force him into the toilet.

Lubitz, 27, crashed the Airbus A320 passenger jet into the Alps changing the aircraft's altitude to just 100 feet using the autopilot, sending it on collision course with the Alps.

German prosecutors believe that Lubitz may have added a chemical to Captain Patrick Sodenheimer's coffee to remove him from the flight deck.
