Her Family did not want Her there, is what I read somewhere. That must of been here, this is My only News source.
From the article: "They {the Richardson family} lost a court fight to bury her at a location of their choosing."
The Kennedys forced the burial to be at the Kennedy's cemetery near their family compound, and then they dug her up and moved her to a plot in remote corner away from from the plots of other Kennedys.
#$%^&#@ Kennedys!
