Fatal cut-throat injuries: a retrospective comparative autopsy study of homicidal and suicidal deaths

When a person dies from a deep cut across the throat, the path to determining how that death happened can be fraught with uncertainty. In the world of forensic science, the manner of death is the official classification of whether a death was a homicide, a suicide, an accident, or something that cannot be determined. While the external wound might look similar in different scenarios, the story behind it is often hidden in the details of the body's internal damage and the circumstances surrounding the scene. Distinguishing between a self-inflicted wound and an attack by another person is one of the most difficult tasks a medical examiner faces, because the anatomy of the neck is so compact that a single sharp object can sever major blood vessels, the windpipe, and the spine with devastating speed. When witnesses are absent and the scene offers no clear clues, the autopsy becomes the primary source of truth, yet even the most skilled examiners can find that the physical evidence overlaps significantly between victims who took their own lives and those who were killed by others.

To navigate this complexity, a team of forensic pathologists in Türkiye conducted a detailed review of forty-three fatal cases involving cuts to the throat. They examined the medical records and autopsy reports of these individuals, who had died between 2021 and 2025, to see if specific patterns emerged that could reliably separate the two groups. The researchers looked at everything from the direction of the cut and the presence of defensive wounds on the hands to the specific internal injuries found in the neck, such as damage to the carotid arteries or the spine. They also considered the environment where the body was found and whether drugs or alcohol were present in the system. The goal was not to find a single "smoking gun" that would instantly solve every case, but to identify which features appeared more often in homicide cases and which were more common in suicides, thereby helping to build a clearer picture for future investigations.

The study revealed that while there is a great deal of similarity between the two groups, distinct trends did appear when looking at the data as a whole. In cases ruled as homicides, the victims were far more likely to have sustained defensive injuries, which are cuts or bruises on the hands and arms that occur when a person tries to block an attack. These victims also frequently suffered damage to the carotid artery, the large vessel that supplies blood to the brain, as well as injuries to the windpipe and the bones of the neck. In contrast, the cases classified as suicides showed a different set of characteristics. These individuals were much more likely to have "hesitation marks," which are small, shallow cuts near the main wound that suggest the person made several tentative attempts before delivering the fatal blow. They were also more likely to have similar hesitation cuts on their wrists and to show a specific pattern where the main wound tapered off at one end, becoming shallower and narrower. Furthermore, toxicology reports indicated that a significantly higher number of suicide victims had drugs in their systems compared to the homicide victims.

However, the researchers were careful to emphasize that these patterns are not absolute rules. A person with a defensive wound is not automatically a homicide victim, nor does the absence of hesitation marks guarantee that a death was not a suicide. The study found that many features, such as the exact location of the cut on the neck, the number of wounds, and injuries to the jugular vein or the voice box, appeared with similar frequency in both groups. This means that no single finding can definitively prove how a death occurred. Instead, the value of these findings lies in the cumulative weight of the evidence. When a medical examiner sees a combination of defensive injuries, deep arterial damage, and signs of a struggle at the scene, the likelihood of homicide increases. Conversely, the presence of hesitation marks, a tapered wound, and drug use points more strongly toward suicide.

The study also highlighted the importance of the scene itself. In the homicide cases where information was available, there was often documented evidence of a struggle, such as displaced furniture or signs of a physical fight, whereas the suicide scenes tended to be more orderly. Yet, even with these clues, two of the forty-three cases in the study remained classified as undetermined, illustrating that sometimes the evidence is simply not enough to reach a firm conclusion. The authors concluded that determining the manner of death in these tragic cases requires a holistic approach, weaving together the physical evidence from the body, the toxicology results, and the context of the scene. While the patterns identified in this research offer valuable guidance, they serve as part of a larger puzzle rather than a standalone solution, reminding us that the truth in forensic pathology is often found in the integration of many small details rather than a single dramatic discovery.
