Anne Heche was trapped in her vehicle as fire quickly spread and onlookers worked desperately to get her out ... and the panic plays out in the 911 call from the scene.
The caller -- who appears to be a neighbor of the home Anne crashed into -- tells the dispatcher Anne's car went through the home "very fast." At first, it doesn't appear the caller is aware of the fact Anne is trapped in the car, but you can hear people yelling in the background making it clear that someone is in trouble.
The call gets much more desperate when smoke starts to surround the vehicle -- and the caller works to get a water hose to the crash scene.
You can start to hear sirens in the background as the caller states the smoke is getting really black and fire breaks out ... and there's more shouting in the background about someone being trapped.
TMZ broke the story, it was August 5 when Anne crashed into the home -- an event that put her in a coma and eventually killed her. Law enforcement sources told us the actress had cocaine and possibly fentanyl in her system at the time of the crash.
Anne was declared brain dead Friday and taken off life support on Sunday, a medical team worked to harvest some of her organs for donation.
