Trick or treaters? (in disguise) might be indicative of a closet homosexual either with or looking for a steady relationship with another. If that went wrong, or disease made him unfit for flight duty, maybe that would be a motive.
another poster posted the link to the alleged girlfriend’s FB page, Kathrin Goldbach. The profile pic was a cute blonde but the larger banner pic was a pretty Arab girl in front of a sunset over water.
If the FB profile is real it is either incredibly tacky and thoughtless or an ‘in your face’ taunt by Muslims.
