Sigtuna

Sigtuna is linked to the investigation through a boarding-school circle whose members include both murder victims and perpetrators. Rather than serving in the cited scenes as a crime scene, it functions as a point of connection: the shared school history helps reveal how apparently separate people belong to the same network.

The Boarding-School Connection

When Jeanette Kihlberg explains the investigation to Sofia Zetterlund, she reports that almost everyone involved had attended a boarding school in Sigtuna. The statement broadens the case beyond the immediate question of who killed particular victims: it points to a shared past among people connected to the crimes, while leaving the precise nature of that school experience unstated.

Former Students in the Case

Jeanette identifies Hannah Östlund and Jessica Friberg as the killers of Karl Lundström and Per-Ola Silfverberg, and says they were also responsible for killing a homeless woman in a cavern. She reports that Hannah and Jessica have died by suicide. The school connection thus encompasses both women named as perpetrators and men identified as victims, as well as another killing connected to the investigation.

The Sigtuna Circle

During a later conversation with Annette Lundström, Jens Hurtig writes down names associated with the Sigtuna group and initially concludes that all its members have been murdered except Hannah and Jessica. He then notices an exception and asks whether Victoria Bergman will be present. Annette’s surprise and denial leave Victoria’s relationship to the group unresolved in that exchange. Together, these references make Sigtuna a key organizing clue: the shared school past gathers scattered names into a recognizable circle, but does not by itself explain each person’s role or establish that the crimes took place there.
