NEW YORK -- A woman died after she was set on fire while sleeping on a New York City subway car Sunday morning in Brooklyn, according to police. A person of interest was taken into custody later in the day, New York Police Department Commissioner Jessica Tisch said at an early evening news conference.

A woman set on fire inside a New York City subway has raised questions about how a world traveler and former Merck employee ended up homeless and burned on a train.

Three teenagers are being rewarded for turning in the man who allegedly set a woman on fire on a New York City subway in December.

Update: The three teenagers who helped police find the suspect accused of fatally setting a woman on fire in a New York City subway station will receive the reward money after all, NYPD officials said Friday.
