To add to this, Bergwall has actually been acquitted of almost all murders he was convicted of, much to the chagrin of chief prosecutor Van der Kwast I'm sure. The one exception is the murder of Charles Zelmanovits, which was appealed in February this year. That case was closed on July 31st.
The worst part of this scandal is that since Bergwall didn't commit six of these murders up to six other murderers are walking free to this day.
For those wondering, he's @StureBergwall on Twitter. I could translate some of his tweets if anyone's interested.
edit: I misinterpreted the verdict on the Zelmanovits case - Bergwall was actually acquitted of that too, meaning he didn't commit any of the murders.
