While I don't know the specifics of the incident, I kept wondering if the auto-lock feature in the car deterred the occupants form getting out, and prevented the rescuers from opening the car doors.
My car came with the auto-lock feature programmed in. I had my dealer de-activate it after reading about a car-fire incident in an Audi, where it was rear-ended, smashing the battery, thus cutting power to the door locks. The occupants were subsequently burned as they could not get out.
Here's an example of the designers being too fancy and worked too hard just to have a 'cool' feature in the car.
I just hope that did not contribute to buring tragedy. Everyone please drive safe. Life is precious.
