Eastern Indiana police say two people died in a car fire along Interstate 70 near Richmond on Sunday afternoon after an occupant lit a cigarette as another person in the car was using medical oxygen. Of the car’s four occupants, the two in the back seat died after flames engulfed the car. The two in the front seat were able to escape, but with severe burns. The fire prompted police to close westbound lanes of I-70 for nearly three hours. Authorities have not yet released the names of the two deceased passengers.
