“…Postmortem radiography and imaging has been recommended as standard practice in veterinary medicolegal investigations and the feasibility of Virtopsy in animals has been investigated . Serial postmortem imaging of the thorax and abdomen in dogs and postmortem radiographic findings in the abdomen of cats are described . In a series of six dog cadavers examined at 22–33°C, the liver was a primary site of intravascular gas identification, occurring in the hepatic veins and portal branches .…”

“…I n humans, the use of cross‐sectional postmortem imaging for medicolegal investigations or virtual imaging has rapidly expanded over the past 15 years and is now routine in many jurisdictions . Veterinary forensic radiology and imaging research has focused on postmortem imaging and identifying radiographic features of nonaccidental trauma; how e ver, research opportunities and practical applications of forensic radiology and imaging in veterinary medicine are abundant and growing . Imaging studies are often provided as evidence in medicolegal investigations involving humans or animals.…”

Imaging studies are often of evidentiary value in medicolegal investigations involving animals and the role of the veterinary radiologist is to interpret those images for courts as an expert or opinion witness. With progressing interest in prosecuting animal crimes and strengthening of penalties for crimes against animals, the participation of veterinary radiologists in medicolegal investigations is expected to increase. Veterinary radiologists who are aware of radiographic and imaging signs that result in animal suffering, abuse, or neglect; knowledgeable in ways radiology and imaging may support cause of death determinations; conversant in postmortem imaging; comfortable discussing mechanisms and timing of blunt or sharp force and projectile trauma in imaging; and prepared to identify mimics of abuse can assist court participants in understanding imaging evidence. The goal of this commentary review is to familiarize veterinary radiologists with the forensic radiology and imaging literature and with the advantages and disadvantages of various imaging modalities utilized in forensic investigations. Another goal is to provide background information for future research studies in veterinary forensic radiology and imaging.

“…Due to the timing of cadaver availability and amount of time necessary to complete the procedures in each cadaver, it was necessary to refrigerate half of the cadavers for up to 24 hours. A 2009 study by Heng et al revealed postmortem changes in canine cadavers including gas accumulation in the pleural cavity and lung collapse as noted by an alveolar pulmonary pattern on radiographs, with severe decomposition apparent as early as 24 h from the time of death when stored at an ambient temperature of 22–33°C . It was suspected that cold storage would slow these processes.…”

Investigation of animal-related crime, and therefore submission of forensic cases to veterinary pathology facilities, is increasing, yet many veterinary pathologists are unfamiliar and often uncomfortable with involvement in the forensic necropsy. This article discusses various aspects of the forensic necropsy without specific attention to any particular species group or crime. General advice is given on procedures, documentation, and recording of the examination, and the article indicates how these features may differ from those used in investigation of natural disease. It also discusses evidence management, including recordkeeping, identification of evidence, labeling of photographs, and use of standard operating procedures and protocols. Various written and visual methods for documentation of the forensic necropsy are covered, and adjunctive topics such as sample collection, assessment, and description of wounds and taphonomy are included. Cause, mechanism, and manner of death are defined, and guidance to the use of these terms is given. The aim of this article is to offer guidance on procedural aspects of the forensic necropsy that will help those developing their forensic services, contribute to standardization of the provision of forensic veterinary pathology, and build the confidence of the ''uncomfortable'' forensic veterinary pathologist.
