I’ve been trying to find out more about this because the story doesn’t make any sense:
“he approached the sleeping woman, and then lit her on fire with what was believed to be a lighter. She added the victim’s clothes became fully engulfed in a matter of seconds.”
Clothing shouldn’t just be flammable like that without some kind of accelerant.

Polyester propagates pretty easily if the fire is big enough. It only “self extinguishes” sometimes when the gloop of melted plastic falls off, or if the flame is small. But a large flame will for sure spread, especially if it’s a thin and airy fabric or a blend.
