Here the "Brattåsmannen" is arrested - see the police's own photos

The unique images from the arrest of the 45-year-old man are included in the new SVT documentary "Dna-spåret: Double murder in Brattås" in three episodes, all of which were released on SVT play on the night of Thursday. Program manager is Carina Bergfeldt.

The documentary tells the whole story of the extremely brutal double murder of Tor Öberg and his special resident Gerd Viklund, both in their 70s, on Tor's farm in Brattås outside Härnösand in the early summer of 2005.

It tells about the problems in the investigation, and about the top-down of nearly 800 people who did not yield a hit on the DNA trace that was secured at the crime scene. About the relatives' long-standing struggle to gain knowledge. And about the unexpected breakthrough this spring, which led to the arrest and detention of a man who had so far been completely unknown both to the police and to the victims' relatives.

Several weeks of preparation

The arrest became possible after he could be linked to the DNA trail from the crime scene. After that, experts at the Swedish Medical Examiner's Office and the National Forensic Center managed to create a DNA profile - which the police's DNA genealogists in turn were able to trace to the man in question.

After several weeks of preparation, where the man was secretly arrested in his absence, he was finally arrested. By then, the police had carefully mapped his habits and behavior patterns.

- When we entered the apartment, the man was sitting in an armchair with his computer on his lap. He only noticed us when we took the computer from his lap, says one of the police officers who was present at the arrest, in the SVT documentary.

"Very nice feeling"

When the DNA match was confirmed, police investigation manager Josefine Perming Tengqvist and her colleagues could breathe a sigh of relief.

- It was a very nice feeling that we got confirmation that we were right, she says in the documentary.

The man, who denies any crime at all, was sentenced on September 9 this year to 14 years in prison for aiding and abetting murder in two cases. The verdict has been appealed and the case will go up in the Court of Appeal for Lower Norrland on November 5.
