Underground Murder

One morning, a young man left for work to meet his colleagues at the metro station as he always did. They claim that he was acting unusual the morning of the accident, then without a word, he suddenly turned and ran from the train. With contradicting eyewitness reports, no one can give a positive account of the incident. It is unclear what truly happened at first glance, but they all have one thing in common: witnesses stated that he simply fell to his death.
