NEW YORK (CNN) - Police are searching for a woman they say pushed a man to his death on a New York train platform Thursday.
Just released surveillance video of the woman they believe is the suspect.
Witnesses say the woman was pacing on the seven train platform in Queens, talking to herself before she took a seat. When the train pulled into the station, she got up and pushed the man onto the tracks, they say.
Then witnesses tell authorities she ran away. There was no indication that he noticed she was behind him.
Police say the man was struck by the first car and pinned by the second, as the train of 11 cars came to a halt.
Police have not identified the victim.
