Reports said the vehicle was traveling about 100 miles per hour when it hit a curb, a tree, a light post and another tree, triggering the fire.

He was transported to a New York hospital, where he was pronounced dead hours later.

''Stephanie told me, 'Mommy kept saying, I can't stop. The brakes don't work. I can't stop.' She said that mommy was in a complete panic," Caroline recalled. "Stephanie grabbed the hand brake.

"Given the heavy fire and smoke conditions, it wasn't that you could clearly see into the vehicle or clearly be able to access it," LAFD Deputy Chief Richard Fields explained to the NBC 4 I-Team. "Heavy smoke conditions, heavy fire conditions, which makes it very difficult for us to just see each other on the inside of a working structure fire."
