Smilla Discovers That a Muscle Biopsy Was Taken from Isaiah After His Death

Smilla’s discovery that Isaiah received a muscle biopsy after death exposes a concealed act within what officials have treated as a routine accident. A small puncture in his rain pants, matched to a mark in his thigh, becomes a forensic clue that the body was sampled after his heart stopped—and that the official account leaves an important intervention unexplained.

The clue in the rain pants

The finding emerges from the autopsy performed by a forensic specialist at the Institute of Forensic Medicine at the University Hospital. The examination began the morning after Isaiah’s body arrived. The institute had been occupied with other cases, and the specialist did not begin work on Isaiah until eight that evening. He describes the procedure as routine: an external examination, inspection for material under the fingernails and other signs, followed by examination of the internal organs.

Isaiah was wearing Helly Hansen rain pants. The specialist says he checked the legs with a light bulb inside them, a practical technique he had developed in his profession. Near the thigh, he noticed a perforation in the garment, then found a corresponding hole in the tissue. He acknowledges that he should have noticed it during the initial surface examination, but what changed the significance of the hole was the lack of bleeding and tissue contraction. Those signs indicated to him that the puncture had been made after Isaiah’s heart stopped.

From mark to biopsy

The rain pants also carried a small indentation around the hole. That detail connected the garment to the wound in the thigh and prompted the specialist to use a biopsy needle—a large syringe-like instrument with a handle, used to remove a tissue sample. He compared the procedure to the core sampling used by geologists. The needle’s dimensions and the indentation appeared to fit: someone may have inserted it forcefully and in haste.

The specialist’s conclusion is emphatic but remains an inference from the physical evidence. He says he would stake his hat on someone having taken a muscle biopsy from Isaiah. The puncture was not simply an unexplained mark: its position in the rain gear, its match to the tissue opening, and the absence of signs of circulation made the timing central. It was a postmortem procedure, not an injury sustained before death.

Excluding the routine explanation

The specialist considers whether the ambulance medic might have taken the sample. He says he contacted the ambulance crew, speaking to both the driver and the medic, and also asked the orderlies who received Isaiah’s body. All denied doing it. Their denials do not identify who took the sample, but they remove the obvious explanation that it was part of the known transfer or intake of the body.

This leaves the biopsy as an intervention whose operator and purpose are unknown. The evidence establishes neither who ordered it nor what the sample was intended to reveal. Its significance lies precisely in that gap: a procedure took place after death, yet the people responsible for the body’s ordinary handling disavowed it.

An omission with investigative consequences

Smilla asks why Johannes Loyen did not tell her about the finding. The specialist seems, for an instant, about to explain, but the moment of candor ends before he provides an answer. He mutters that it must be a coincidence. His retreat leaves the key issue unresolved: whether Loyen knew of the biopsy, why the discovery was absent from what Smilla had been told, and whether the silence was deliberate.

That omission matters because Smilla is already contesting the official description of Isaiah’s death. In an earlier conversation, an investigator asserted that the police report showed Isaiah had been alone on the roof and that there was no indication of anything other than an accident. He also insisted that the examination had been thorough. The biopsy evidence does not by itself disprove the fall or establish a different cause of death, but it complicates the claim that the case contains nothing beyond an accident: someone performed an unexplained procedure on Isaiah’s body after death.

Evidence, authority, and the limits of proof

The discovery turns an apparently minor discrepancy into a challenge to the boundaries of the investigation. The official position invokes forensic thoroughness and the absence of evidence of assault; the biopsy, by contrast, is evidence of an unaccounted-for act. Smilla’s later threat to file a complaint is met with permission to do so, but the exchange does not resolve the question the biopsy raises. The institution’s confidence in its report and Smilla’s concern about what has been omitted remain in tension.

The finding also connects to the book’s wider pattern of medical evidence whose meaning depends on who examines it and what is disclosed. A specialist interprets the puncture through the physical correspondence between garment, tissue, and biopsy needle, yet cannot identify the person responsible. The result is neither a complete forensic solution nor a mere suspicion: it is a concrete postmortem act that the available explanations fail to account for. Smilla’s discovery therefore changes the shape of Isaiah’s case without settling it, making the unexplained sample itself a reason to continue asking what happened after his death.
