A grandmother seeks justice for Native Americans after thousands of unsolved deaths, disappearances

Yolanda Fraser is back near a ragged chain-link fence, blinking through tears as she tidies up flowers and ribbons and a pinwheel twirls in the breeze at a makeshift roadside memorial in a small Montana town. This is where the badly decomposed body of her granddaughter Kaysera Stops Pretty Places was found a few days after the 18-year-old went missing from a Native American reservation border town. Four years later, there are still no answers about how the Native American teenager was killed.
