District Attorney Kristian Nicolaisen argued for forvaring for Khan, extended preventive custody that can be used to potentially extend a sentence to life incarceration, on the grounds that there was a danger the Norwegian-Pakistani could kill again.
The court did not rule in favor of forvaring, explaining that it was unlikely he would emerge from such a long prison sentence with his drug problems intact.
Khan was on a variety of drugs, vodka and rohypnol when committing the crimes.
The three sisters Nafisa, 13, Saadia, 24, and Sobia, 27, were struck down with an axe and murdered in their semi-detached home in the Kalbakken district of Oslo. One of the sisters was also shot with a pistol on the night of October 1, 2006.
When the trial began the brother declared himself partially guilty, and testified that he could not remember carrying out the killings, but realized that he must have been responsible.
