Both prosecutor Bertil Månsson and the suspect’s lawyer Fredrik Lindberg have painted a picture of a young man who felt like an outsider – not physically abused, but overlooked by his stepfather. Thoughts of revenge grew in the suspect’s mind. He kept it to himself and no one in his family sensed anything was wrong.

The siblings were surprised by the attacks. His 15-year-old half-brother was slashed by a knife in the hall when he came home from school. Afterwards, he went into the living room with the knife in his hand where his unsuspecting half-sister lay on the sofa and watched television. About an hour later, he stabbed his former stepfather to death with an axe.

On Tuesday, a psychiatric evaluation established that the man was seriously mentally disturbed when he murdered his half-siblings and their father. He is still severely mentally ill, according to the examination, and should instead be submitted to psychiatric care.

Both the lawyer and the prosecution will call for the 21-year-old to be sentenced to secure psychiatric care.
