For 42 years, investigators wondered what happened to Cheryl Miller and Pamela Jackson on May 29, 1971 -- the night the teen girls disappeared.
Today, they have a much clearer picture of that night.
The girls' skeletal remains were found in an overturned car in Brule Creek last September. DNA testing results released today confirm those remains were Miller and Jackson.
South Dakota Attorney General Marty Jackley said investigators found the car in third gear, lights on, and there appeared to be damage to one of the car's tires.
Miller's purse, along with notes and her drivers license, was found in the car.
Jackley says alcohol doesn't appear to be a factor in the accident. One of the girls had visited her grandmother just before disappearing.
Kay Brock, Jackson's sister, told us yesterday that the DNA confirmation lifts decades of uncertainty.
"I'm relieved to have no foul play," Brock said. "It's nice to have a permanent answer after 42 years."
