Months after the mysterious roadside deaths of a Florida mom and her 3-year-old daughter, officials in Orlando have revealed the cause. The lifeless bodies of Latifa Lincoln, 45, and her daughter, Maksmilla Lincoln, were discovered in the mother’s Porsche Cayenne on the Florida Turnpike back in June. The car was still running when a state trooper spotted the SUV and the radio was turned on.
After a rigorous investigation, a medical examiner said Tuesday the deaths were caused by hydrogen sulfide intoxication, likely as the result of a defect in the car’s battery… The colorless gas has a pungent odor and first responders were forced to retreat from the vehicle after they approached it and saw Lincoln and her daughter, who did not appear to be breathing.
