Van Gogh wasn't the most stable person psychologically, remember he sliced off his ear and delivered it to a brothel. In a fit of depression or rage he could have shot himself. A tortured genius.
Another famous firearm thought lost forever, the FN 1910 in 380 ACP that Gavril Princip used to kill Archduke Franz Ferdinand and Archduchess Sophie, the event that set off World War I, it turned up a few years ago.
Once Princip had been apprehended, his pistol was, for unknown reasons, given to the Jesuit priest who administered the last rites to Ferdinand and his wife. The Jesuits eventually turned over the gun to the Vienna Museum of Military History.
