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.
