Is this the Movie With the Rock Burial?
I remember seeing a movie when i was a kid in the 70's. The town took someone who did something wrong and buried her under rocks until she smothered. I think I remember them being like Quakers or Amish or something like that. It's the only scene I remember. Is this the movie? I'm NOT thinking of The Lottery either. In that one she was stoned to death.
