On October 13, 2021, five victims were fatally stabbed. Anderson Brathen is also charged with 11 counts of attempted murder for firing on people with bows and arrows in the 26,000-strong former mining town of Konsberg.
He is accused of causing bodily harm, threatening behavior, refusing to obey police orders and throwing knives at officers.
The attack began inside a grocery store. Anderson Brathen was arrested more than half an hour later on charges of starting to shoot arrows inside the store and attacking people inside their home.
He read the allegations aloud on Wednesday and listened quietly. Although he admits, he may not end up in a Norwegian prison.
Prosecutors want him punished with mandatory mental health care, saying he was in a “strongly deranged state of mind” during last year’s attack, according to charging documents obtained by the Associated Press.
Following his arrest, Anderson Brathen was admitted to a closed psychiatric ward. Three forensic psychiatrists who assessed him concluded that he was probably insane at the time of the murder.
The hearing is expected to last a month.
