The husband claims (and he should certinaly know) that his wife was LEAVING the house that morning.
The fire was allegedly cause by antifreeze being ignited by the HID headlights
the antifreeze was released by the radiator being punctured by the vehicle crashing into a workbench
These simple things are absolutely impossible to happen in the way they are stating, and here is why:
1) Radiators are not pressurized like an aerosol can is. They come to be pressurized by thermal expansion as the coolant absorbs engine heat and expands.
2) If she was LEAVING for work that morning at 5:00 AM, the coolant would not be warm yet so no expansion would occur. A leak of any size would cause the coolant to simply drip to the floor, and not be atomized.
3) Absent atomization, the coolant would have a MUCH higher flash point.
4) Similar to the coolant, the headlights would not reach their full oprating temperature for a period of time after they were turned on. Anything less than full operating temperatures would severly limit their ability to cause anything to get to it's flash point, even gasoline
5) Headlights are physically shielded from the radiator. It would take quite a lot of atomization to create a cloud large enough to even reach the headlights.
6) The headlight bulbs are further removed physically by thier plastic housings. In order for the atomized vapors to reach the bulb itself, the housings would have to be breached. Anything less than a complete breach would limit the amount of vapor that could get to the bulb.
7) A bulb that is in the warm-up phase would generate positive thermal expansion itself, with the surrounding air expanding away from the heat source.
The above alone eliminates the possibility of this occuring as claimed. When you add the other factors (husband not concerned about her being in the car, radiator punctured while exiting the garage, no air bag deployment in a crash strong enough to compromise the radiator and the headlight housings), to accept the explanation provided you must suspend all logic.
I would normally not give a news story like the fire and her death a second thought, but when the investigators attempt to fed us this line of BS my radar goes up and I become suspicious.
Why was BATF involved?
Why wasn't the husband frantic when he saw her BMW was in the fire?
What sort of people/things was she recently involved in?
What is with the information that she was unconcious prior to the fire?
Why do the investigators state that there is no suspicion of foul play?
Color me extremely suspicious.
You do good research. You bring one question to my mind. Thermal expansion. How long prior was the car driven and how long would it take for the pressure to subside? I have not read near enough on this story but if she was only home for an hour or two would that have caused the pressure to remain much higher than you anticipate with a ‘cold’ start?
