According to the forensic psychiatric report, the man suffered from a serious mental disorder both at the time of the murders and at the time of the investigation.
The forensic examination, carried out by the National Board of Forensic Medicine, follows a minor so-called paragraph seven examination that indicated that the man could be mentally ill.
It was in March that the police were alerted to a residential area, where a young man and a woman were found dead. The suspect, a 19-year-old man, was arrested outside in connection with the scene. According to police and prosecutors, all three belong to the same family.
The man has confessed to the murders
The suspect confessed to the murders in the first interrogations. He has been detained on probable cause on suspicion of two counts of murder since March 10.
"The case involves a family of four who live at the crime scene. No outsider is suspected of a crime. A man and a woman in the family are deceased and a 19-year-old man is suspected of a crime. The father of the family is a witness to parts of the course of events and is himself the plaintiff for a serious unlawful threat", prosecutor Åsa Valter has previously said in a press release.
According to the prosecutor, the victims were murdered with a sharp weapon.
In the forensic psychiatric examination, the assessment is that the man is in need of forensic psychiatric care.
