What happened
Two young girls were murdered in the Baneheia recreation area in Kristiansand in 2000, producing one of Norway’s most consequential criminal cases.
The investigation
Jan Helge Andersen confessed to one killing and implicated Viggo Kristiansen. Early DNA interpretation and Andersen’s account helped secure convictions against both men.
What the courts or investigators concluded
After the case was reopened, Kristiansen was acquitted in 2022 while Andersen remained criminally responsible and later faced renewed scrutiny concerning the second victim.
Why the case remains significant
The case is now a central Norwegian example of tunnel vision, problematic expert interpretation and the importance of independent review when forensic evidence is uncertain.
