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.

The woman who was set on fire on the NYC subway has been identified as Debrina Kawam, of Toms River, New Jersey, police say.

Authorities have released the identity of the sleeping woman burned to death inside a New York City subway train by a man who allegedly lit her on fire and stayed to watch the aftermath, officials said Tuesday.
