Why Did Peter Johansson Kill Police Officers in Blood Sacrifice?

Netflix’s Blood Sacrifice spends most of its five episodes hiding the identity of the person behind the gruesome attacks on Stockholm police officers. The finale finally unmasks Peter Johansson as the so-called 112 Killer, but his motive is more complicated than a simple hatred of the police.

Peter is a former police officer whose partner, Hugo Brankovic, died during an emergency call after desperately needed backup failed to arrive. What destroyed Peter afterward was the discovery that the police records made it appear as though he had never asked for help at all. Blamed for Hugo’s death and abandoned by the institution he had served, Peter eventually turned his anger into a murderous campaign against other officers.

What Happened to Peter Johansson and Hugo Brankovic?

Two years before the main events of Blood Sacrifice, Peter and Hugo responded to a 112 call involving a domestic disturbance.

The situation quickly became violent. Hugo was pulled inside the apartment by the armed man and stabbed. Peter remained outside and radioed for backup, but help did not arrive in time. By the time the confrontation ended, Hugo was dead. For Peter, the trauma did not end there.

When the incident was investigated, there was apparently no official record showing that Peter had called for backup. Instead of being regarded as an officer who had desperately tried to save his partner, he was treated by colleagues as someone who had failed Hugo. Peter knew that wasn’t what happened.

His attempts to challenge the official version went nowhere, while his reputation inside the department collapsed. Eventually, his grief became mixed with an obsession over proving that the police system itself had sacrificed him.

Why Did Peter Become the 112 Killer?

Peter’s murders are designed around the same system that failed him.

He uses the 112 emergency service to lure police officers into traps. One of his cruelest methods involves recordings of previous victims. A victim’s voice can be used to create the next emergency call, sending another group of officers to a location where Peter is waiting.

The repeated time of 1:15 a.m. is also significant because it connects the murders back to the night Hugo died.

Peter therefore isn’t picking random methods simply to avoid getting caught. He is repeatedly recreating elements of the tragedy that destroyed his life.

In his mind, the officers he kills represent an institution that refused to take responsibility for Hugo’s death and then allowed Peter to carry the blame. The murders become his distorted attempt to force the police to experience the same vulnerability and abandonment that he experienced.

That explains Peter’s anger. It does not justify what he does.

Most of his victims had nothing to do with Hugo’s death. Peter turns a genuine institutional failure into an excuse for murdering people who were not responsible for it.

Why Does Peter Want to Kill Alfred Berg?

Peter’s ultimate target is not just another patrol officer. It is Alfred Berg.

Peter believes Alfred was responsible for what happened on the night Hugo died because Alfred had been working around the police dispatch operation. Peter eventually comes to see Alfred as the senior figure who must pay for the failure that ruined both Hugo’s life and his own.

That belief is why Peter kidnaps Alfred near the end of the series and builds his final act around him.

But there is a major problem with Peter’s revenge: he has blamed the wrong man.

The finale reveals that Lucas Lind was actually responsible for failing to properly respond to Peter’s request for backup. Lucas then erased evidence of the calls, protecting himself while allowing suspicion to fall on Peter. Alfred’s name became connected to the incident, leading Peter toward the wrong conclusion.

It makes Peter’s entire revenge campaign even more tragic. There really was a cover-up, and Peter really was treated unfairly, but he spends years building his vengeance around an incomplete version of the truth.

What Does the Midwinter Sacrifice Painting Have to Do With Peter?

The strange arrangement of Peter’s victims comes from Carl Larsson’s famous painting Midvinterblot, usually translated as Midwinter Sacrifice.

The painting depicts the legendary Swedish king Domalde being sacrificed after repeated crop failures. The basic idea Peter takes from it is that the person at the top must be sacrificed for the failures that occurred under his authority.

The painting also has a personal connection to Hugo, who admired it.

Peter eventually twists its meaning into a framework for his revenge. Police officers become sacrifices, while Alfred becomes the symbolic “king” Peter believes must ultimately pay for what happened.

That also helps explain the show’s title. Blood Sacrifice is not referring only to the literal bloodshed. Sacrifice is the central idea linking Peter’s murders to the police department’s behavior.

Peter believes the institution sacrificed him to save itself. He then responds by sacrificing innocent officers in his attempt to punish the institution.

Peter’s Motive Makes the Real Villainy More Complicated

By the finale, Peter is exposed as the killer, but the show does not completely absolve the police department.

Lucas really did fail Peter. Evidence really was concealed. Peter really was allowed to become the scapegoat for a mistake someone else made.

The difference is in what each person does afterward.

Lucas protects himself at another person’s expense. Peter responds to that injustice by murdering people who had no responsibility for Hugo’s death.

That is what makes the reveal more interesting than simply discovering the killer’s name. Peter Johansson became the 112 Killer because he believed the police had sacrificed Hugo and then sacrificed him to protect itself. His grievance began with something real, but his response transformed him from a victim of the system into the person terrorizing everyone within it.
