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.

Authorities in New York have released the cause and manner of death of a woman who was set aflame inside a subway car earlier this month. Debrina Kawam, a 61-year-old resident of New Jersey, died from "thermal and inhalational injuries," the New York City Chief Medical Examiner confirmed to PEOPLE on Tuesday.
