The woman was reported missing the day before she was found but has not been seen since December 13.
She was found dead under the municipality's large Christmas tree at Medborgarplatsen and the police have investigated the case.
Froze to death
The autopsy results have been delayed, but now preliminary investigation leader Anette Krig confirms the cause of death.
- She has ended up under the tree because she has laid down there.
The final autopsy report shows that the woman has frozen to death, says Krig to Norr media.
