Some more sensational newspapers claimed that a Luger pistol with one round fired was found among the wreckage and speculated that a person on board committed suicide or shot the airship. However, there is no evidence suggesting an attempted suicide or official report confirming the presence of a Luger pistol. Initially, before inspecting the scene himself, Eckener mentioned the possibility for a shot as the cause of the disaster, because of threatening letters they received. At the German enquiry Eckener discounted a shot – among many possibilities – as the cause as nearly impossible and highly improbable.
