The suspect, a man in his 20s, was shot dead by police.
"We are just standing there and stamping our feet. We have no known relationship between him and the people who were at the address. If there is one, the investigation will show," says PO Andersson, criminal inspector at the police's serious crimes unit in Luleå.
It was at lunchtime on Christmas Day that the police were called to a villa in Boden where several people had been attacked with a cleaver.
Someone at the address is calling the police. We are being called due to some type of assault in a residence. Then we learn more things along the way.
The silence about the injured
A 55-year-old woman was killed and two other people were taken to hospital with injuries, where they continue to be treated.
Out of consideration for the victims and their relatives, neither the Public Prosecution Service nor the police want to provide any information about the injured or whether more people were in the villa.
According to Aftonbladet's information, the perpetrator was in the home for several hours, something PO Andersson neither wants to confirm nor deny.
A threatening situation arises when we arrive at the scene and this leads to the police opening fire at the man, says Andersson about the fatal shooting.
Looking for tips
The perpetrator has "connections to" Boden and the police had "some knowledge" of him previously, according to the criminal commissioner. The police are appealing for tips and observations that can be linked to the incident.
The police are interested in obtaining information that may seem like a trifle to the individual, but which for us can be a small piece of the puzzle.
The incident is being investigated as murder and attempted murder.
Police misconduct is investigated by special prosecutors' chambers with the support of the police's special investigations department.
