NEW YORK (AP) - Investigators were looking for a man who witnesses said was mumbling to himself on a subway platform before and after he pushed another man down onto the tracks in front of an oncoming train Monday afternoon, resulting in that man's death, police said.
The pushed man, 58-year-old Ki-Suck Han, of Queens, tried to climb back up onto the platform a few feet above and died after getting trapped between the train and the platform's edge, police said.
The incident occurred around 12:30 p.m. Monday at 49th Street and Seventh Avenue in Manhattan, where N, Q and R trains stop, and transit officials said the incident involved a southbound Q train.
Witnesses described the suspect as a man in his 20s wearing a white t-shirt. Police are reviewing surveillance camera footage.
Patrick Gomez, 37, of Saddle Brook, N.J., was waiting on the platform for the southbound train. As it pulled into the station and slowed down, he "heard a thud that didn't sound normal."
Then he saw people screaming and running from the other end of the platform.
"They looked like they were in shock," he said.
Police evacuated the platform within minutes, Gomez said, and back up on the street, he saw the man who'd been hit brought up on a stretcher. He said the man looked older, and was motionless.
"This is very jarring - suddenly, in the middle of the day in midtown Manhattan," Gomez said.
The New York Post says one of its freelance photographers was on the platform as the ordeal unfolded. Umar Abbasi says he tried to warn the subway operator by flashing his camera. One of his photos shows Han on the tracks, arms on the platform, looking at the train as it bears down on him.
Subway pushes are unusual. Among the more high-profile was the January 1999 death of Kendra Webdale. A former mental patient admitted he shoved her to her death.
Following that, the state Legislature passed Kendra's Law, which lets mental health authorities supervise patients who live outside institutions to make sure they are taking their medications and aren't a threat to safety.
