A Norwegian court has sentenced Philip Manshaus to 21 years in prison. He was convicted for killing his sister and attacking the Al-Noor Mosque in Bærum.
The case reopened last year to determine his mental state during the 2019 attacks. The court examined whether Manshaus could be held legally responsible for his actions.
Judges concluded he was fully aware of his actions during both incidents. They stated the evidence proved his sanity beyond reasonable doubt.
Court documents reveal detailed reasoning behind the verdict. Officials found no signs of psychosis during his violent acts.
The Al-Noor Mosque attack shocked Norway's Muslim community. It raised concerns about far-right extremism in the country.
Bærum residents remember the 2019 incident as deeply traumatic. Local communities have worked to rebuild trust since then.
Norwegian courts rarely issue life sentences for single murders. The 21-year term reflects the severity of both crimes.
Legal experts note this case tested Norway's mental health laws. The verdict confirms courts will hold extremists accountable regardless of their ideological motivations.
