As terrified passengers poured out of a smoke-filled train after pulling into a Brooklyn subway station, Sam Carcamo watched in horror. “I saw fear in some of the people's faces. Someone was crawling cause they had fallen over. People are screaming, running towards me,” Carcamo told Inside Edition. The 35-year-old says he was about to transfer from a local to an express train at 36th Street in Sunset Park, when a gunman detonated smoke bombs and opened fire on passengers inside a moving train.
