The woman must have been injected with a syringe while she was sleeping, according to a witness heard in the investigation. The man himself has denied any wrongdoing.
It was on November 22 last year that the police were called to an apartment in the central parts of Norrköping. At the scene, a dead woman was found. The 45-year-old was also in the apartment, who was arrested and has been in custody since then.
Previously convicted of a crime
The man has a background as a gang criminal and has previously been convicted of several crimes.
Now the 45-year-old is being sentenced for murder and assault against an official after an incident during custody when, according to the verdict, the man threw a cup of urine at a correctional officer.
The reason for the death
The district court makes the assessment that syringe injection with narcotics was what caused the death. It was clear after the coroner and toxicologist were heard during the trial.
A forensic psychiatric examination has shown that he suffers from a serious mental disorder. After the forensic psychiatric care is completed, the man must be deported for life, according to the Norrköping district court.
