Researchers seek lost Native American boarding school graves

In this undated photo provided by National Archives, some students at the former Genoa Indian Industrial School in Genoa, Nebraska line up outside the school. Researchers are now trying to locate the bodies of more than 80 Native American children buried near the school in central Nebraska. For decades, the location of the student cemetery has been a mystery, lost over time after the school closed in 1931 and memories faded of the once-busy campus that sprawled over 640 acres in the tiny community of Genoa.
