Hassan Samriye Hashin had admitted the murder. An appeals court also found him guilty of raping 19-year-old Hedda Karterudseter at Sogndal Folkehøyskole on October 28, 2004.
Hashin had followed Karterudseter home to her student apartment and admitted strangling her in a fit of jealousy. He denied raping her.
He had been sentenced to 16 years in prison by a lower court, which also found him guilty of both murder and rape. The maximum prison term in Norway is 21 years.
