Her body was found hanged in a barn.
There are no witnesses to the hanging. That she hanged herself is an assumption only.
The first thing I thought was that this just happened today, and already the news report is conclusive that it was suicide? Since it's the Kennedys, if it WASN'T suicide, we'll never know.
So she was killed? Because she wouldn’t give him a divorce? Because she knew too much? If this were 50 years ago you might have a good case for murder, but how likely is that now, when divorce is more readily available? And RFK Jr. is pretty small potatoes. Whatever you could say about his father and uncles, it’s hard to see anyone being killed to save his pathetic little (non-)career.
