Default US mother and her three-year-old daughter may have been gassed to death in car by faulty battery

Quote:
Latifa Lincoln, 45, and her three-year-old daughter, Maksmilla, were found dead alongside Florida's Turnpike in their 2006 Porsche Cayenne
Medical examiners struggled for four months to determine what caused their deaths on May 13
Lab and urine tests confirmed that they inhaled excessive amounts of hydrogen sulfide
Investigators are now trying to determine whether the gas was leaked from the Porsche Cayenne car battery
Unlike most other vehicles, the Porsche Cayenne's battery is located under the driver's seat rather than underneath the hood
http://www.dailymail.co.uk/news/arti...r-battery.html


First responders who arrived at the scene reported smelling a foul
odor. Three of them even had difficulty breathing


That their deaths were caused by hydrogen sulfide inhalation seems indisputable. The first-responders testimony indicates high levels inside of the car.

But I can't work out how the battery could have caused this. It is my understanding that overcharging a car battery will release hydrogen and oxygen gasses, but hydrogen sulfide?

It seems possible.Many GM cars have their batteries under the back seat with vent tubes hooked to them to bleed off any gasses..
If someone installed the wrong battery and it was defective or overcharging with no vents it could happen..

From my knowledge of chemistry, H2S is NOT associated with battery charging or even a defective battery..,

This is a pretty odd occurrence.

I found a link to "Chemical Suicides" that discusses generation of H2S.

Another article discusses "Detergent Suicides."

If the battery is under the seat, it makes me wonder about some kind of interaction with the seat padding - foam rubber or whatever is used now.

I would be looking at the Catalytic converter and exhaust leaks .

As I recall a Catalytic converter can produce hydrogen sulfide
towards the end of its life .

I bet she could not afford to replace the exhaust system
and was aware of a smell for some time .

Now a failing catalytic converter has possibilities.

The wrong size battery was put in. It wasn't the original. One time Sears did that to one of my cars. Every time the hood was opened and closed it did damage to it. It eventually fried some electronic system in my car. I wonder if it didn't do the same thing here.
