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.

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

The "person of interest" was taken into custody hours after the attack while riding another train, according to NYPD Transit Chief Joseph Gulotta.
