    Piophila casei (Linnaeus) (Diptera: Piophilidae) is reported from human cadavers in two separate forensic cases for the first time in Malaysia. Both bodies were found indoors. The first case, was that of a male of unknown nationality and age and also contained maggots of the muscid Ophyra spinigera (Stein). The second case was a female Chinese whose body also contained other species of maggots but these were not identifiable.

    Cadaver body bags are the conventional method to contain a human body or human remains, which includes the use for storage and transportation of the deceased at any crime scene or disaster scene. During disasters, most often than not, the first responders including the police will be equipped with cadaver body bags to do scene processing of human remains and collection of personal belongings at the disaster site. However, in an unanticipated large scale disasters involving hundreds and thousands of fatalities, cadaver body bags supplies may be scarce. The authors have therefore innovated the cling film plastic wrap as an alternative for the cadaver body bag used at the disaster site. The plastic wrap was tested on six different experimental subjects, i.e. both adult and child mannequins; body parts of the mannequin figure (arm and hand); a human adult subject and an unknown dead body. The strengths of the cling film plastic wrap are discussed in comparison with the cadaver body bag in the aspects of costing, weight, duration of the wrap, water and body fluid resistant properties, visibility and other advantages. An average savings of more than 5000% are noted for both adult body wrap and child body wrap compared to the cadaver body wrap. This simply means that the authors can either wrap 25 adult dead bodies or 80 children dead bodies with the cost of 1 cadaver body bag. The cling film plastic wrap has proven to have significant innovation impact for dead body management particularly by the first responders in large scale disasters. With proper handling of dead bodies, first responders can manage the dead with dignity and respect in an overwhelmed situation to facilitate the humanitarian victim identification process later.

    INTRODUCTION: Autopsy is one of the most important approaches to identify clearly the exact cause of death, whether it was due to natural causes, sudden death, or traumatic. Various studies have been done in different countries regarding ways to improve the diagnosis during autopsy. The imaging approach is one of the methods that has been used to complement autopsy findings and to enhance the diagnosis for achieving the most accurate post-mortem diagnosis. The aim of this study is to identify the role of imaging modalities that complement routine autopsy and correlate the findings of diagnostic imaging that can help improve the accuracy of diagnosing the cause of death.

    METHODS: We sourced articles from Scopus, Ovid and PubMed databases for journal publications related to post-mortem diagnostic imaging. We highlight the most relevant full articles in English that explain the type of modality that was utilised and the added value it provided for diagnosing the cause of death.

    RESULTS: Minimally invasive autopsies assisted by imaging modalities added a great benefit to forensic medicine, and supported conventional autopsy. In particular the role of post mortem computed tomography (PMCT), post mortem computed tomography angiography (PMMR) and positron emission tomography computed tomography (PMCTA) that have incremental benefits in diagnosing traumatic death, fractures, tissue injuries, as well as the assessment of body height or weight for corpse identification.

    CONCLUSION: PMCT and PMMR, with particular emphasis on PMCTA, can provide higher accuracy than the other modalities. They can be regarded as indispensable methods that should be applied to the routine autopsy protocol, thus improving the findings and accuracy of diagnosing the cause of death.

    Death-in-custody refers to the occurrence of death, while a person is under the custody of any enforcement agency. Their incidence often creates overwhelming public and media attention. Currently, there is no standardised definition of 'death-in-custody' in Malaysia and internationally. A crosssectional descriptive study was performed in the Department of Forensic Medicine Hospital Tuanku Ja'afar Seremban (HTJS) for a period of 24 months. Information on all custodial deaths registered at HTJS from January 2001 till December 2015 was selected from the in-house hospital death registration system. The definition of 'death-in-custody' used was guided by the recommendation by the 'Australian Royal Commission into Aboriginal Deaths in Custody' 1991 with few adjustments. Four custodial settings of interest (the police, prison, immigration depot for the illegal immigrant, and army custody) were studied. A total of 172 deaths-in-custody were collected, in which the majority of cases were natural deaths (84.88%), predominantly infective in nature (65.07%). Less than 1/6th of cases were unnatural deaths with more than 80% died from legal intervention. All custodial deaths were dominated by males (96.51%) with a mean and median age of 37 years. In terms of nationality, 52.91% of the deaths involved Malaysian citizens in which the 'Malay/Bumi' race outnumbered the other two main races. The most documented custodial deaths occurred in prison (44.19%) followed by immigration depots (38.37%) and police lock-ups (17.44%). This study provides a general overview of the pattern including the causes and the demographic profile involving death in custody in the Seremban district registered at HTJS.

    Domestic maid violence is an assault and coercive behaviour, which mainly includes physical, psychological and at times sexual too, by employer or household members of employer against a person hired as a domestic help. Maid abuse is well known but poorly documented in scientific literature. This is an important global issue. In this article, two illustrated cases of maid abuse are discussed. Their employers allegedly subjected both the victims to physical and psychological trauma. The physical examination of the victims showed poor state of clothing, nutrition, and presence of injuries of different duration. The bruises were irregular to patterned, and were inflicted by beating. Both cases had eczematous contact dermatitis over palms and soles, paronechia, and sub-ungal fungal infection due to unprotected working in wet conditions. In both cases, external ears were deformed like cauliflowers due to repeated trauma. All cases had multiple injuries of varying duration. In this paper, medico-legal and social issues related to maid abuse are also discussed in detail. A possible solution to minimise maid abuse is also suggested. This paper highlights and document maid abuse.

    The requirement of the medical graduate, tabled in the objectives of undergraduate medical education, as envisaged by the Malaysian Medical Council, call for the all round basic doctor to be able to handle any medical emergency, as well as meet the requirements of law in examining, documenting and reporting on the common offences of the Penal Code, where medical documentation is required of law for the purposes of dispensing justice. However, in tabling the amended requirements of the undergraduate syllabus on the lines of those followed in sollie of the more developed nations, we seem to have lost this perspective. The authors discuss, based on his previous experience from another former colonial country viz. India, where the objectives of the undergraduate training is the same, and the influences 011 the legal profession bear a common origin and governance, the relevance of some of these topics, coming under the antbit of Forensic Medicine and Toxicology as an undergraduate subject, in the day-to-day practise of medicine in and out of government service. While this issue has been the frequent topic of discussion in international confereilces and symposia, where the decline in the standards of medico-legal work in the coulltries attending have been blanled on the fall in the standard of undergraduate teaching, due recognition of the pitfalls of the deletion or whittling down of the course content, independent of the overall overhauling of the syllabi of medical schools, to keep up to the trends of overseas universities, has not been accorded in the planing of the coursc revisions, resulting in a deletion of a vital aspect of daily practise of medicine.

    True vehicular homicides are defined as those occurrences in which a motor vehicle is intentionally used as a weapon in taking of a life. A case is presented in which the deceased was traveling in the front passenger seat of a motor car that was deliberately rammed by a heavy jeep that came in the opposite direction, resulting in a serious frontal collision. Immediately after the impact, while the occupants of the car were lying in a dazed condition, the two persons riding in the jeep escaped with a bag containing money that was in the car, leaving the jeep behind. The impact mainly involved the driver's sides of both vehicles. The driver of the car sustained serious injuries but was found to be alive, whereas the front-seat passenger, who did not show any serious external injuries, was found to be in a collapsed state and was pronounced dead on admission to the hospital within 30 minutes of the accident. The autopsy revealed that death was caused by closed hemopericardium from a ruptured right atrium. The evaluation of the external and internal injuries confirmed that the fatal injury and a few serious internal injuries were caused by the seat belt (tertiary-impact injuries). The ruptured right atrium was attributed to blunt abdominal trauma by impacting against the lap belt. The case was a true vehicular homicide in which a motor vehicle had been used as a weapon to kill a person. Various aspects pertaining to road accidents, the safety of the occupants, and the advantage and disadvantage of the safety devices are discussed.

    All deaths due to unnatural causes and deaths that are believed to be due to natural causes but where the medical cause of death is not certain or known are subjected to an inquest. The objective of an inquest is to ascertain facts pertaining to the death. This is achieved by inquiry and at the conclusion of the inquest a verdict is arrived as to whether the death was due to a natural, accidental, suicidal or a homicidal cause. An inquest is not a trial. There is no complainant or defendant and at the conclusion of the inquest no judgment is passed. The inquest system exists in all parts of the world. In the English legal system, the person who conducts an inquest is called a Coroner. In Scotland, he is called a Procurator Fiscal. The United States of America use the Medical Examiner system. Most continental European countries and their former colonies follow the Code Napoleon. A postmortem examination may become necessary in certain deaths that come up for inquests. In these situations the authority which conducts the inquest will order a doctor to perform a postmortem examination (medico-legal autopsy). To perform a medico-legal autopsy, consent from the relatives of the deceased is not required. In an unexpected sudden death, only a doctor after a postmortem examination may be able to determine the cause of death. However, it is often wrongly assumed that the objective of a postmortem examination is only to ascertain the cause of death. This article deals with the purpose of the inquest and roles of the medico-legal autopsy.

    Preservation of larvae retrieved from cadavers is important in ensuring the quality and integrity of entomological specimens used for the estimation of post-mortem interval (PMI). The process of killing and preserving larvae could distort the larvae leading to inaccurate estimation of PMI. In this study, the effects of killing Chrysomya megacephala larvae with hot water at different temperatures and subsequent maintenance in various preservatives were determined. Larvae not killed by hot water but preserved directly were used as control. The types of preservative used were 10% formalin, 70% ethanol and Kahle's solution. The morphological features examined were length, turgidity, curvature and coloration of larvae. Larvae killed in 80ºC hot water have shorter mean length (12.47 ± 2.86 mm) compared to those in 60ºC hot water (12.95 ± 2.69 mm). Increasing the duration of preservation in all types of preservative caused elongations of larvae treated or untreated with hot water. There were no significant changes in larval turgidity preserved in Kahle's solution compared to other two preservatives and were unaffected by the duration of storage. Larvae preserved in Kahle's solution experienced the least changes in coloration and shape compared to other preserved larvae in 70% ethanol or 10% formalin. Larvae directly immersed alive in 70% ethanol experienced the most changes in curvature, coloration and turgidity. This study suggested that killing larvae with hot water at 80ºC and preservation in Kahle's solution is the optimum method resulting in least changes in morphological features of Ch. megacephala larvae.

    Organ weights are routinely measured during autopsies as a crude screening tool to detect possible organ pathology. In several centers, inclusion of major organ weights indicates whether an autopsy report has achieved its standard of practice, which in turn should be subjected to an audit. Previous studies show statistical variation in organ weights across different populations. Malaysian pathologists have relied on Western data and crude subjective determination in the interpretation of normal organ weights. Hence, the need for a reference range as a guide for pathologists is acute. Organ weights from traumatic deaths between 2004 and 2017 were analyzed in the UKM Medical Centre. Statistical analysis was performed to form reference ranges for normal weights of the brain, heart, lung, liver, spleen, and kidneys. In addition, the data were compared between sexes, races, and body mass index values to determine whether organ weights were affected by these parameters. In this study, reference ranges for organ weights are presented for Malaysian adult men and women.

    The main aim of this study is to determine the causes and the epidemiological aspects of sudden natural deaths. Data were collected from 545 sudden natural autopsies in UMMC, Kuala Lumpur over a five-year period, from 1st January 2000 to 31st December 2004. There were 475 males and 70 females. The largest number of sudden natural deaths was in the age group of 41-50 years. 35.8%, 30.5% and 11.7% of the patients were Chinese, Indian and Malay, respectively. A majority of the patients were married (59.8%) and came from the semiskilled-unskilled group (30.6%). The monthly distribution was almost constant. Cardiovascular diseases were the most important cause contributing 64.9% in sudden natural deaths.

    Decomposing carrion provides a temporary microhabitat and food source for a distinct community of organisms. Arthropods constitute a major part of this community and can be utilized to estimate the postmortem interval (PMI) of cadavers during criminal investigations. However, in Malaysia, knowledge of carrion arthropod assemblages and their succession is superficial. Therefore, a study on three types of forensic entomology animal model was conducted from 27 September 2010 to 28 October 2010 in a tropical rainforest at National University of Malaysia, Bangi, Selangor, Malaysia. Over one month collections of arthropods were made on nine animal carcasses: three laboratory rats (Rattus norvegicus, mean weight: 0.508 ± 0.027 kg), three rabbits (Oryctolagus cuniculus, mean weight: 2.538 ± 0.109 kg) and three long tailed macaque (Macaca fascicularis, mean weight: 5.750 ± 0.551 kg). A total of 31,433 arthropods belonging to eight orders and twenty-eight families were collected from all carcasses. Among 2924 of adults flies collected, approximately 19% were calliphorids with Chrysomya megacephala (Fabricius, 1794) being the most abundant. Arthropod taxon richness was lower on rat carcasses compared to that of rabbit and monkey carcasses, and this was more apparent during the first week of decomposition. However, there were no significant differences in Shannon-Weiner index (H'), Simpson dominance index (C) and Pielou's Evenness index (J) between different animal model. The arthropod assemblages associated to animal model were different significantly (p<0.05) while decomposition stage was a significant factor influencing insect assemblages (p<0.05). Analysis on the arthropods succession indicated that some taxa have a clear visitation period while the others, particularly Coleoptera, did not show a clear successional pattern thus require futher insect succession study. Although human bodies were not possible for the succession study, most of the arthropods collected are necrophagous, and will also possibly colonize human cadaver, and potentially be useful in assisting in estimates of PMI in future forensic cases in Malaysia.

    This paper discusses the colonization of the stratiomyid species Ptecticus melanurus (Walker) (Diptera: Stratiomyidae) in monkey carrion and its potential for the determination of the minimum time since death (PMI). A study was conducted in a tropical forest at Bangi, Malaysia from 13 November 2009 to 8 June 2011. Twelve monkey carcasses (Macaca fascicularis Raffles) were used and divided in equal number into three different field trials. Adults of P. melanurus were first observed on monkey carrions on the second day the carcasses were placed in the field while their penultimate instar larvae were found in the wet soil under and beside carcass from day 8 to 31 days postmortem.

    Analysis on fly artifacts produced by forensically important blowfly, Chrysomya megacephala (Fabricius) (Diptera:Calliphoridae), revealed several unique patterns. They can be divided into fecal spots, regurgitation spots and swiping stains. The characteristics of fecal spots are round with three distinct levels of pigmentation; creamy, brownish and darkly pigmented. Matrix of the spots appears cloudy. The round spots are symmetrical and non-symmetrical, delineated by irregular and darker perimeter which only visible in fairly colored fecal spots. Diameter of these artifacts ranged from 0.5 mm to 4 mm. Vomit or regurgitation spots are determined by the presence of craters due to sucking activity of blowflies and surrounded by thickly raised and darker colored perimeter. The size of these specks ranged from 1 mm to 2 mm. Matrix of the spots displays irregular surface and reflective under auxiliary microscope light. Swiping stains due to defecation by flies consists of two distinguishable segments, the body and tail. It can be seen as a tear drop-like, sperm-like, snake-like and irregular tadpole-like stain. The direction of body and tail is inconsistent and length ranged between 4.8 mm to 9.2 mm. A finding that should be highlighted in this observation is the presence of crater on tadpole-like swiping stain which is apparent by its raised border characteristic and reflective under auxiliary microscope light. The directionality of this darkly brown stain is random. This unique mix of regurgitation and swiping stain has never been reported before. Highlighting the features of artifacts produced by flies would hopefully add our understanding in differentiating them from blood spatters produced from victims at crime scenes.

    Insects found associated with corpse can be used as one of the indicators in estimating postmortem interval (PMI). The objective of this study was to compare the stages of decomposition and faunal succession between a partially burnt pig (Sus scrofa Linnaeus) and natural pig (as control). The burning simulated a real crime whereby the victim was burnt by murderer. Two young pigs weighed approximately 10 kg were used in this study. Both pigs died from pneumonia and immediately placed in an oil palm plantation near a pig farm in Tanjung Sepat, Selangor, Malaysia. One pig was partially burnt by 1-liter petrol while the other served as control. Both carcasses were visited twice per day for the first week and once thereafter. Adult flies and larvae on the carcasses were collected and later processed in a forensic entomology laboratory. Results showed that there was no significant difference between the rate of decomposition and sequence of faunal succession on both pig carcasses. Both carcasses were completely decomposed to remain stage after nine days. The species of flies visiting the pig carcasses consisted of blow flies (Chrysomya megacephala, Chrysomya rufifacies, Hemipyrellia ligurriens), flesh fly (Sarcophagidae.), muscid fly (Ophyra spinigera), soldier fly (Hermetia illucens), coffin fly (Phoridae) and scavenger fly (Sepsidae). The only difference noted was in the number of adult flies, whereby more flies were seen in the control carcass. Faunal succession on both pig carcasses was in the following sequence: Calliphoridae, Sarcophagidae, Muscidae, Phoridae and lastly Stratiomyidae. However, there was overlap in the appearance of members of these families. Blowflies continued to oviposit on both carcasses. Hence postmortem interval (PMI) can still be estimated from the partially burnt pig carcass.

    BACKGROUND: Palatal rugae are asymmetric ridges of connective tissue located behind the incisive papilla over the anterior hard palate. They serve as stable superimposition landmarks to assess tooth movement in orthodontics and as identification aids in forensic odontology. However, the stability of palatal rugae remains controversial. This review aimed to describe the genetic, growth, and environmental factors that may influence the palatal rugae patterns. A broad search of PubMed and ScienceDirect databases was conducted. A total of 193 articles were identified, of which 73 met the selection criteria. Data were extracted into a table that presented the details of the study, sample description, and changes in the palatal rugae patterns.

    HIGHLIGHT: There were conflicting results regarding sexual dimorphism and population characterization of the palatal rugae patterns. All rugae showed positional changes, increased lengths, and lower numbers, but no significant shape changes with growth. The lengths, numbers, and positions of the rugae were affected by orthodontic treatment, especially their lateral points, but their individual characteristics did not change.

    CONCLUSION: The diversity in rugae patterns and their potential for sex discrimination among different populations showed differing results due to individual variations and the complex influence of genetic, growth, and environmental factors on their morphology.

    Law enforcing authorities need to provide a scientific basis for the identification of any unknown individual. In recent years, dental records comparison has developed into one such credible method of confirming the identity of a deceased. This method is however restricted as dentists are not making and maintaining adequate records of their patients. Fortunately the advent of inexpensive cameras and print processing procedures has enabled the availability of ample antemortem photographs. Photographs in which a person expresses his/her teeth 'gleefully' has provided a sound scientific basis for the identification by comparing dental characteristics of the deceased.

    While forensic medical tasks are usually associated with supporting the criminal justice system, there are a range of forensic medical skills that can be brought to bear on addressing humanitarian activities. Disaster victim identification is a procedure that has achieved international standardisation through the work of a multinational Interpol Standing Committee. While part of a police organisation, it includes forensic pathologists, anthropologists, odontologists and molecular biologists who provide most of the specialist scientific input regarding identification that is integrated with police processes such as document examination and fingerprinting. The loss of Malaysian Airlines Flight MH17 represented a major activation of these procedures in an environment that had both humanitarian and forensic criminal investigation components. The information that is derived from the processes involved in disaster victim identification has a value that goes far beyond the determination of identity. It has an important humanitarian role in supporting the family and friends of the victims in their bereavement journey.
