NEW YORK (AP) — Police searched for a woman who killed a man by pushing him in front of a subway train and released surveillance video Friday of her running away from the station.

Commuters, meanwhile, absorbed the news of the second fatal subway shove in the city this month.

"It's just a really sad commentary on the world and on human beings, period," said Howard Roth, who takes the subway daily. He said the deadly push was food for thought about subway safety, "but I guess the best thing is what they tell you — don't stand near the edge, and keep your eyes open."
