The medicolegal death investigation in Victoria, Australia is a traditional coroner system based on the model in England and Wales in the early 20th Century. In 1985, the first of a series of legislative amendments were made that proved the vanguard of reform of the coroners' jurisdictions in Australia. The Victorian Institute of Forensic Medicine (the Institute) was established by the Coroners Act 1985 (Vic.), now the Victorian Institute of Forensic Medicine Act 1985 (Vic.), to provide forensic pathology, medical, and related scientific services needed by the justice system. In addition to death investigation, other forensic and scientific services are performed by the Institute including: clinical medical examinations and support services for assault victims and perpetrators, forensic toxicology services and molecular biology, and anthropology and odontology services in relation to human identification. Medical and nursing staff provide medical information and support to families in a therapeutic setting, as well as direct referral to clinical medical specialists. This takes place where a medical death investigation procedure uncovers genetic or familial disease that may place other family members at risk of future illness. A donor tissue bank ensures that a death also provides the opportunity for families to donate organs and tissues from the deceased for transplantation. Today, the traditional autopsy is one of several modalities of death investigation with postmortem radiology and imaging playing a significant role. This paper describes the principles and new processes at the Institute that support the coroner in death investigation and prevention as well as the therapeutic services designed to relieve the burden of disease on the community.

AbstractMitragynine is the primary active alkaloid in the leaves of the tropical tree Mitragyna speciosa, and goes by the popular names “Kratom”, biak-biak and maeng da. Mitragynine is increasingly seen in forensic toxicology casework including driving under the influence of drugs and medicolegal death investigation cases. The toxicity of mitragynine continues to be debated in the scientific community as advocates highlight its long history of use in Southeast Asia and testimonials to its benefits by present-day users, while opponents point to an increasing number of adverse events tied to mitragynine use in Western societies. Quantitative reports of mitragynine in biological specimens from forensic investigations in the literature are sparse and may be influenced by poor analyte stability and inadequate resolution of mitragynine from its diastereomers, which could lead to falsely elevated concentrations and subsequently render those reported concentrations inappropriate for comparison to a reference range. Over the course of 27 months, 1,001 blood specimens submitted to our laboratory tested positive for mitragynine using a sensitive and specific quantitative LC-MS/MS method; concentrations ranged from 5.6–29,000 ng/mL, with mean and median concentrations of 410 ± 1,124 and 130 ng/mL, respectively. Mitragynine presents an analytical challenge that requires a method that appropriately separates and identifies mitragynine itself from its isomers and other related natural products. We describe a validated analytical method and present a short series of case reports that provide examples of apparent adverse events, and the associated range of mitragynine concentrations. This type of analytical specificity is required to appropriately interpret mitragynine concentrations detected in biological specimens from forensic casework and assess its potential toxicity.

Medicolegal death investigation agencies must provide timely final autopsy reports in order to meet minimum accreditation standards. To ensure a timely turn around, the principles of case management were introduced into an agency with a large metropolitan jurisdiction. Forensic autopsies are typically complex and the associated ancillary studies often include forensic toxicology along with various specialty consults. Beginning in 2013, a forensic case management service was initiated to aid forensic pathologists in reducing report turnaround time. Despite increasing number of cases in 2014, the agency was able to maintain the accreditation standard of 90% turn around within 90 days. The case management service required process improvement, technology to track and trend, and increased interdisciplinary collaboration. The implementation of a case management system within the forensic autopsy service can improve processes to reduce report turnaround times.

Researchers often have a need to conduct human tissue research using postmortem specimens. Medicolegal death investigation organizations are untapped areas for obtaining postmortem human tissues. Because death investigation organizations are not required by law to conduct or support research, an ethical dilemma exists in whether or not researchers should use cadaver tissues for research purposes. This paper analyzes the ethical issues of using human tissues through discussion of principles of biomedical ethics, respect for autonomy, nonmaleficence, beneficence, and justice. Policy makers, organ and tissue procurement organizations, medicolegal death investigation organizations, and scientists should be aware of these principles when considering researchers requests. The authors conclude that with Institutional Review Board approval and next of kin consent, there are prevailing reasons for using postmortem tissue for research.

Modern forensic medicine was introduced into China during the first decades of the 20th century. The members of China’s first generation of medicolegal experts were soon advocating that medical expertise play a greater role in police and judicial officials’ investigations of suspicious death and homicide cases. While forensic reform in China had parallels with developments in other contemporary societies in which physicians were pushing for a greater role in the law, this process unfolded in China in unique ways, against the backdrop of an older tradition of forensic science that had developed under the Qing dynasty (1644-1911). Central to this tradition was the Records on the Washing Away of Wrongs, a handbook of forensic practice that was written in the 13th century and saw numerous editions and expansions over subsequent centuries. Death investigation in early 20th-century China was defined by “forensic pluralism,” a situation in which the different body examination methods and standards of forensic proof associated with the Washing Away of Wrongs and modern forensic medicine were both accepted by officialdom and society. This article untangles the complexities of forensic practice during this period through the rather unexceptional exchange over a case of suspected drowning that occurred between local officials in Hebei province and Lin Ji (1897-1951), director of the Beiping University Medical School Institute of Legal Medicine. This case reveals the different regimes of forensic knowledge and practice that were used in China during this period as well as the sites at which they interacted.

Forensic toxicology and forensic medicine are unique among all other medical fields because of their essential legal impact, especially in civil and criminal cases. New high-throughput technologies, borrowed from chemistry and physics, have proven that metabolomics, the youngest of the “omics sciences”, could be one of the most powerful tools for monitoring changes in forensic disciplines. Metabolomics is a particular method that allows for the measurement of metabolic changes in a multicellular system using two different approaches: targeted and untargeted. Targeted studies are focused on a known number of defined metabolites. Untargeted metabolomics aims to capture all metabolites present in a sample. Different statistical approaches (e.g., uni- or multivariate statistics, machine learning) can be applied to extract useful and important information in both cases. This review aims to describe the role of metabolomics in forensic toxicology and in forensic medicine.
