Samuel Bai’s murder and disfigurement

Samuel Bai’s murder and disfigurement is presented as a staged death whose forensic details contradict its appearance as a hanging. Found in an attic in the Monument block, the sixteen-year-old had been missing after running away from home. His case becomes significant not only for what the crime scene reveals, but also because his treatment by Sofia Zetterlund draws Jeanette Kihlberg’s attention to a connection with another case.

Discovery and setting

The body was discovered in an attic in the Monument block, near Skanstull on Södermalm. The discovery came at roughly the same time that Karl Lundström was attempting suicide in Kronoberg Prison. The timing places the two incidents side by side in the narrative, but the crime scene initially offered little to suggest that the boy had been killed by the same perpetrator responsible for the earlier bodies.

A resident of the building found Samuel while apparently looking for a box of old records to sell. Several storage areas along the corridor had also been broken into, making it possible that he had been searching for saleable property when he came upon the body. Investigators did not have evidence implicating him, though they did not rule out his involvement; he was taken for questioning. The circumstances of the discovery therefore supplied a lead to check, not an established explanation for the murder.

Forensic reconstruction

Samuel had been left hanging from an ordinary clothesline tied with a granny knot. The forensic examination identified a ligature mark consistent with hanging, but the scene did not support suicide. The crucial contradiction was practical: the cord was at least ten centimetres too short for Samuel to have fastened it to the ceiling himself, even if he had stood on a bench. Investigators also found a ladder nearby and a bench arranged beneath the body, details that allowed them to reconstruct how someone might have staged the scene.

The evidence indicated that Samuel had been suspended alive. The forensic officer noted signs of involuntary bodily response, further distinguishing the scene from a self-inflicted death. The ladder and bench appeared to have been used to create the impression that Samuel could have reached the ceiling and arranged the cord himself; the rope’s length undermined that appearance. Taken together, the scene details led the investigators to treat the death as a homicide rather than accept the hanging at face value.

His face had been disfigured by a corrosive substance. At first the damage resembled burns, but the rest of the body and the clothing bore no signs of fire. Splash marks on the floor and nearby wall, together with a dried yellow stain, supported the suspicion that acid had been thrown at him. The forensic officer assessed it as fairly strong hydrochloric acid, while noting the danger to whoever handled it. Ivo Andrić offered a possible source for the substance: the wall appeared new, and builders sometimes use acid to prepare old brickwork so plaster will adhere. That possibility explained how acid might have been present, but did not establish who used it or why.

Ivo proposed that the disfigurement might have been intended to conceal Samuel’s identity. This remained an initial hypothesis, not a confirmed motive. The acid’s possible connection to building work, the damage to Samuel’s face, and the staged hanging leave distinct questions open: how the substance was obtained, why it was used, and what the killer intended the scene to suggest.

Samuel and the investigation

Samuel was sixteen and had been reported missing after running away from home. Social-services case notes forwarded from Hässelby recorded drug abuse, theft, and violence. Those reports form part of the investigators’ available background, but do not explain the killing or establish a motive.

His parents had fled the war in Sierra Leone and had been the subject of numerous investigations. The family’s most pressing difficulty, according to the case information, had been Samuel’s trauma from the war. He had received intermittent treatment at a child-psychiatry centre on Maria Prästgårdsgata and had also seen a private therapist, Sofia Zetterlund.

That therapeutic connection changes the case’s place in Jeanette’s investigation. On learning that Sofia had treated Samuel, Jeanette recalls that Sofia had also treated Karl Lundström. Her recognition does not prove that the cases share a perpetrator or cause; it marks an unexpected overlap among people already appearing in separate inquiries. The link makes Samuel’s history relevant beyond the attic crime scene and gives Jeanette another reason to examine how the cases may be connected.

Significance

The murder turns on the difference between a scene’s appearance and what its physical arrangement permits. A body hangs from a cord, a bench lies beneath it, and a ladder is nearby; yet the cord is too short for the supposed suicide to have been carried out as staged. The forensic reconstruction converts those ordinary objects into evidence of deliberate arrangement.

The acid disfigurement introduces another unresolved layer. Concealment is suggested as a possible purpose, while the newly plastered wall offers a separate, tentative explanation for the chemical’s presence. Neither hypothesis is resolved by the evidence available at the scene. Meanwhile, the identification of Samuel and the disclosure of his treatment by Sofia connect the case to the wider investigation without confirming that the crimes have the same source. The event’s force lies in that combination: a fabricated appearance of suicide, a victim whose history is only partly known, and a connection that prompts suspicion but does not yet settle the pattern.
