Investigators have learned the name of a woman who was burned alive — and beyond recognition — aboard a Brooklyn train last week.

The 57-year-old, of Toms River, N.J., was set on fire as she slept in an F train stopped at the Coney Island-Stillwell Ave. station on Dec. 22.

The homeless woman torched to death at a Brooklyn subway stop has been identified as a 57-year-old woman from New Jersey, officials said Tuesday. Debrina Kawam of Toms River, NJ, was set on fire as she slept in an F train stopped at the end of the line at Coney Island-Stillwell Avenue station about 7:30 a.

It took police more than a week to publicly identify Debrina Kawam, 57, as the woman who was fatally set on fire in a New York subway train last month. But on the internet, it took just hours for a false name to begin spreading.
