Cases of postmortem canine predation often involve elderly recluses and their dogs. The face, head, and genitalia are targeted. Two unusual cases of postmortem canine predation of abandoned newborns are described to demonstrate an unusual alternative pattern of mutilation related to the small size of the decedents, marked decomposition, and canine scavenging behavior.

Alternate light sources such as ultraviolet, narrow band, and infrared have been used in an attempt to reveal the presence of bruising that is not otherwise apparent.

The following study evaluates the ability of alternate light sources to enhance visibility of bruises by employing an objective assessment of digital photography images in conjunction with histology. A pigskin model was employed with bruises created by injection of blood to be not visible or barely visible (inapparent) under white light.

Data were analyzed for age, sex, time of year/season, place of discovery, circumstances of death, and underlying medical conditions. Despite the considerable demographic, geographic, and climatological differences, hypothermic deaths occurred at very similar rates in South Australia (3.
View Article and Find Full Text PDFA review of hypothermic deaths was undertaken using cases from the Charité University, Berlin, Germany and Forensic Science South Australia, Australia. There were 16 cases from Berlin (age range 38-96 years; average 68 years; M:F = 13:3) Wischnewski spots were present in all 16 cases (100%), skin discolouration in nine (56%), and acute pancreatitis and muscle haemorrhage in one case each (6%). There were 62 Australian cases (age range 30-89 years; average 67 years; M:F = 13:18).

Body core temperatures dropped to a minimum of 7-10 °C, causing death under anaesthesia at times varying from 120 to 240 min.

Experimental studies have been successfully performed using animal models to replicate this finding, however study animals have inevitably been subjected to a variety of additional stressors including food deprivation, restraint and partial immersion in water while conscious. As it is recognised that stress on its own may cause superficial erosive gastritis, a model has been developed to enable the study of the effects of hypothermia in isolation.

Toxicological analysis had been performed in 555 (68 %) from a total of 815 autopsies. It was found that the proffered manner of death was changed from the provisional report (provided immediately after the post-mortem examination) in five cases (just under 1 %) as a consequence of the toxicological findings.

Assessment of injuries in marine mammals may be required to help authorities determine whether human activity was involved. Three cases of marine animal deaths involving propeller blade strikes are reported to demonstrate characteristic features of such cases and diagnostic difficulties that may occur. Case 1: A juvenile New Zealand fur seal (Arctocephalus forsteri) suffered two parallel linear incised wounds of the flank and died following small intestinal herniation.

Human trafficking of young men from Africa to Europe is a crime with often devastating consequences. The African continent loses members of the younger generation and many die during the attempt to reach their destinations. The identification of these victims is often difficult, however the structured and by now well-established procedures utilizing standard disaster victim identification protocols provide a reliable and functional approach.

An underwater disaster may involve a crime scene investigation which should be handled as if it were located above water and include a detailed description and documentation of items, belongings and findings. The environment, however, creates special circumstances, each with specific problems that are not encountered during land investigations. Risks associated with underwater recovery cannot be overestimated and underwater disaster recovery diving should not be performed without special training and careful pre-dive planning.

Review of the Australian National Coronial Information System and the Swedish National Forensic Database was undertaken over a 7-year period from 2001 to 2007 for all cases where death had been attributed to autoerotic death or sexual asphyxia. In Australia, there were 44 cases (M:F = 42:2) with the majority of victims aged >30 years (77%)-a yearly national rate of approximately 0.3/million.

Transfer of knowledge is the cornerstone of any educational organisation, with senior staff expected to participate in the training of less experienced colleagues and students. Teaching in the field is, however, slightly different, and a less theoretical approach is usually recommended. In terms of Disaster Victim Identification (DVI) activities, practical work under supervision of a field team stimulates tactile memory.

Aim: To identify and characterise cases of infant deaths where the fatal episodes were considered to be because of positional asphyxia from wedging and/or suffocation associated with sleeping on or near a mattress that had been placed on a floor.
Methods: Retrospective review of autopsy cases from Forensic Science SA, Adelaide, Australia, was performed over a 10-year period from January 2001 to December 2009 to identify such cases.
Results: A total of five deaths were identified.
