She had just moved to one of Norway's most beautiful villages. And landed a job at the village hotel.

But just seven days later, she disappeared.

A search was initiated, but it was too late. 

18-year-old Trude was found brutally raped and murdered in the most scenic setting.

The case has been described as one of Norway's most extensive investigations, 

but almost 30 years later, police are still searching for answers.
