The judge who presided over Amanda Knox's second murder conviction said he suffered over the verdict but he and the jury agreed about her guilt in the death of British student Meredith Kercher.

Judge Alessandro Nencini said the jury had come up with a motive that would be explained in the written explanation of the verdict, expected within three months.

But he hinted at the conclusion, saying that until 8.15pm on the night of the murder Knox and her then boyfriend Raffaele Sollecito had other plans, but something changed.
