What happened
Sixteen-year-old Sigrid Schjetne disappeared while walking home in Oslo in 2012, prompting a large volunteer and police search.
The investigation
Her body was found weeks later. Investigators used witness observations, vehicle evidence and the movements of suspects to build the case.
What the courts or investigators concluded
A man was convicted of her murder and ordered to compulsory psychiatric care rather than an ordinary prison term.
Why the case remains significant
The investigation is remembered for the scale of public participation in the search and for the challenge of turning a disappearance with few early clues into a prosecutable homicide case.
