Jonas murder case: Appeals court increases sentences for three defendants

In a significant development following the murder of Jonas Aarseth Henriksen, the Borgarting Court of Appeal has handed down harsher sentences to three of the four individuals initially convicted in the district court.

Jonas Aarseth Henriksen, 30, was discovered shot and deceased outside a cabin in Nes, Ådal, on the morning of August 17, 2023. The case was previously heard by the Ringerike, Asker, and Bærum District Court in 2025. At that time, two men were found guilty of committing the murder, while two others were convicted of complicity.

The district court had imposed sentences of 14 years, 13 years, 5.5 years, and 3 years imprisonment. However, the appeals court has revised these sentences substantially. The new penalties are 19 years, 16 years, 5 years, and 4 years and two months for the four accused, reflecting a notable escalation in the severity of the judgments for the majority of the defendants.
