Oslo Police District Violent Crime Investigation Department

The Oslo Police District Violent Crime Investigation Department is the Oslo police unit at the center of a struggle over who may investigate a pair of murders in the city. Led by Gunnar Hagen, it defends local control as more than institutional pride: its officers argue that local knowledge, broad competence, and the ability to choose when outside expertise is needed are essential to effective murder investigations. The dispute with the Norwegian Criminal Investigation Service turns the department’s investigative work into a test of its continued authority.

Mandate and Local Expertise

Hagen describes the department as the country’s largest murder-investigation unit. Its position is that local police should decide which cases they can handle alone, when they need help, and which should be transferred to the national service. The Norwegian Criminal Investigation Service, in Hagen’s account, was established to support local police with specialist expertise in difficult murder cases, not to take the allocation decision away from them.

The department’s institutional argument also concerns the risks of concentrating investigations in one place. Hagen warns that a single centralized unit could become too narrow and insular, losing the advantages of local knowledge and a wide range of investigative experience. He also sees centralization as limiting the recruitment and development of new investigators. These concerns make the jurisdictional contest consequential beyond the immediate case: it may determine whether local police retain a meaningful role in solving murders.

The Double Murder and Jurisdictional Conflict

The immediate dispute follows the discovery of Charlotte Lolles dead behind a Datsun and the recognition of similarities to the earlier killing of Borgny Stem-Myhre. Both bodies were found in Oslo, but the Norwegian Criminal Investigation Service asserted that the linked killings fell within its jurisdiction and began its own investigation. The Ministry’s future support for the agency was understood to depend on the outcome, raising the stakes for both organizations.

The rules themselves had shifted. Hagen explains that Mikael Bellman had used a change in procedure to allow the national service to decide whether a major murder case belonged to it or to the relevant local police force; previously, the decision had run the other way. Bellman’s agency then pursued the case without sharing its information with the Oslo unit. Hagen says the local investigation had stalled, while the agency appealed to the Norwegian Ministry of Justice and the Oslo police chief received a message that the Ministry would welcome a transfer of the case. The department thus faced not only competition in the investigation but also pressure from above to surrender it.

A Covert Investigation

Hagen brings Harry Hole back into the work despite recognizing the personal cost of his previous case. He acknowledges that the last investigation had affected Harry and people close to him, but argues that investigative work is what Harry knows how to do. The new case, Hagen says, involves two murders whose method is not yet understood but which appear identical. The experience gained in the earlier investigation is therefore presented as relevant to recognizing what the department is facing.

Harry asks for a team of three, consistent with his preference not to work with a large group. Hagen accepts the small scale in part because it lowers the chance that the national service or the Ministry will learn that the Oslo department is continuing to investigate. Harry identifies the killing of Marit Olsen as a possible third case: like the other victims, she was a woman alone at night who was taken somewhere and killed in an unconventional way. He treats the apparent pattern as a reason to investigate, while Hagen’s response makes clear that the team must avoid crossing paths with the national agency.

The arrangement carries an explicit institutional risk. Hagen sets the condition that, if the inquiry becomes public, it must not be attributed to the department. The leadership would say that some employees had become involved but describe the investigation as an unauthorized solo venture by Harry, conducted without the department’s knowledge. Harry would have to confirm that account. The unit supplies the conditions for an inquiry while preparing to deny responsibility for it, a contradiction that exposes how little practical protection its formal authority offers under political pressure.

Evidence, Method, and Significance

The case develops through the reconstruction of connections that are not apparent from the victims’ identities alone. Information about Adele Vetlesen’s missing-person report and rail booking places her on a journey from Drammen to Ustaoset on November 7, the same date Borgny Stem-Myhre had booked travel to the area from Kongsberg. A search of Iska Peller’s account also uncovers payment for two beds in each of four mountain huts, with the final booking at Hävasshütte, about half a day’s walk from Ustaoset. These findings do not establish every relationship among the women, but they give the investigators a specific route and shared location to test.

Harry characterizes the results cautiously: they place a missing woman and another woman who may have no connection to the murders in the same area, while strongly suggesting that Charlotte Lolles was accompanied and that Borgny Stem-Myhre and Marit Olsen were near Ustaoset. The distinction between established facts and developing inference matters to the department’s work. Its investigators have to build a case from travel records, accounts, and similarities while operating in the shadow of an agency that is withholding information and pressing for control.

The department’s narrative role is consequently defined by a double bind. Its experience is needed to interpret the murders, yet its institutional standing is threatened by a system that may remove the case from local hands. Hagen’s covert conditions make the investigation possible, but place its personnel, especially Harry, in a position where success may not be publicly credited to the unit and exposure may be framed as unauthorized conduct. The conflict over jurisdiction turns the murder inquiry into a wider question about whether expertise is best exercised through centralized command or through local investigators who know when and how to seek help.
