Medicolegal Death Investigation: Coroner and Forensic Pathology Functions and Processes in Victoria, Australia

Suspension-associated dislocation of the jaw in hanging

Hanging is a common type of death, and the role of the medical investigation of such deaths by a forensic pathologist not only requires the determination of the cause of death but providing information to assist in the determination of the manner of death. The forensic pathologist should be well versed in the spectrum of injuries known to be associated with neck compression, to document injuries known to be associated with hanging, but also to identify those that are inconsistent with self-inflicted hanging or that may suggest the involvement of a third party in the death. Comprehensive identification and correct interpretation of external and internal injury are crucial for the appropriate degree of police and coroner/medical examiner investigation. We present two cases of deaths believed to be caused by self-inflicted hanging that were observed to have unexpected unilateral dislocation of the temporomandibular joint identified on routine post-mortem computed tomography, without any evidence of involvement of a third party. This injury was unexplained and had not been previously observed at our Forensic Institute nor was it identified after a review of the published biomedical research literature. Issues regarding the cause of this abnormality, possible mechanisms, and the medicolegal significance of this finding will be discussed.

The Intersection of Death Investigation and Organ Donation Systems: A Scoping Review

Introduction

Death investigators (DIs) such as coroners, medical examiners, and forensic pathologists play important and evolving roles in deceased organ donation. DIs communicate with organ donation organizations (ODOs) to gather case-specific information and release or restrict organs depending on the medicolegal requirements. This scoping review aims to identify the breadth of roles and decision-making processes that may facilitate or hinder deceased donation in DI cases.

Methods

This study was conducted using a scoping literature review and subsequent thematic analysis.

Results

Thirty-one eligible papers described 8 common themes with region-specific nuances. These include: 1) shared (ODO and DI) protocols for early communication around each case; 2) shared standards and education for death investigation practices related to organ donation; 3) DI support staff or teams to facilitate organ donation; 4) DI authority to order additional testing and imaging before organ recovery; 5) donation-specific legislation to enhance DI and/or ODO operations; 6) legally trained DI authority to veto medical decisions to proceed with organ donation; 7) DI attendance at organ recovery; and 8) surgeons recording specific DI evidence during organ recovery.

Conclusion

These findings have cultural and resource-allocation implications and expose gaps in the international literature describing practices at the intersection of deceased organ donation and death investigation. A better understanding of the rationale and execution of various systems for DI and ODO cooperation may serve to advance both organ donation and death investigation.
