Ooops, my bad. I thought they'd all but matched her handwriting, tablet etc to that note, but didn't have the 'smoking gun' match to make it even semi-offical. I'll have to go back and re-read that '96 case synopsis, when I get some time. Thanks for the clarification.
It was a writing tablet from inside the house, no question. An intruder could have used it, however.
The not totally conclusive part was that Patsy wrote the note. She could not be ruled out, some said, and some apparently believed she wrote it. But it was not something so exact that you could say she was fingered.
They could not prove she wrote it, because if they could have, she would have been indicted.
