The day before the exhibition, Le Prince's brother, Albert, dropped him off at the train station. Le Prince was carrying everything he needed to present the exhibit, including his suitcase with his valuable patents.
What's strange about this is that no one on the train remembers seeing Le Prince.
When he failed to show up at his own exhibit, the police became involved and began their investigation by questioning other passengers on the train. Not one of them could say they had seen him.
The fact that there were other inventors who had hoped to be the first to show the moving picture to the world fueled speculation that one of his fellow inventors was responsible for his disappearance.
This theory was further fanned by Le Prince's wife, Elizabeth, who publicly stated that she believed it to be true.
She claimed that Thomas Edison, in particular, was known to be highly competitive.
Despite many theories surrounding his disappearance, Le Prince was never found, nor was his body.
