The grave of a 12-year-old boy who was hit by a train in 100 years ago has been dug up in a Pennsylvania cemetery.
What police in Butler, about 30 miles north of Pittsburgh, can't figure out is who did it or why. They also don't know if there were any remains still in the grave a century later.
George Olenic, the superintendent of North Side Cemetery, called 911 on Monday night when he found the hole. It was two feet by five feet and four feet deep.
Butler police say they asked forensic anthropologists to determine what might have remained in the grave.
The boy, Walter Roberts, was killed by a train as he was returning from picking blackberries in the woods on Aug. 3, 1911.
