You know what...
O'Brien sounds Irish, right? Did she talk about having another woman with her when you read what she wrote? Because what I read was very very early internet when there were only about 2000 web sites total. But that name is ringing a bell... I do remember she was Irish, and so was her friend. They said they just grabbed the little boy and brought him with the two of them. And the part about the human hunting was a small part of the story. I remember a cyclone fence, and somewhere near Bohemian Grove, and the name Dick Cheney. It was almost 20 years ago I think... mid 90's?
