Two young girls killed in Thursday night's tragic crash on Interstate 75 had just arrived at the airport to spend the summer with their mother and grandmother.
Tiffany Watts and her mother, Sandra Anderson, had just picked up Ms. Watts' daughters, Savannah and Kelsey, according to the Morristown Citizen-Tribune.
All four were killed when a semi barreled into traffic that was being funneled into one lane for a paving project near the Ooltewah exit.
The 2010 Toyota Scion occupied by the three generations of the family was the only vehicle to catch fire.
One of the women in the vehicle was ejected, and those who rushed to the car were unable to save the three people trapped inside from the fire.
Ms. Watts, 31, worked at Morristown-Hamblen Healthcare System and lived at Morristown, Tn. Ms. Anderson, 50, lived nearby at Rutledge, Tn.
Savannah was eight and Kelsey was 10. They lived in California with their father.
