    The return of ex-prisoners who were released from prison into an environment filled with fellow
    friends could lead to negative influences such as drug addiction and crime repetition among former
    prisoners. This paper has been derived from a doctorate study studying the repeatition of crimes that
    occurred among former prisoners in Malaysia. The findings of the study have found that former
    prisoners often return to their fellow members due to family absence. This study has been used
    qualitative methods by interviewing 16 ex-prisoners identified through the technique of snowball
    sampling. The finding revealed that all these former prisoners from different state were concentrated
    around the Chow Kit road. Addiction, as a result of invitation process by friends. This situation are
    make the study to proven relationship between the influence of friends and drug abused among the
    former prisoners.

    Illicit trade carries the potential to magnify existing tobacco-related health care costs through increased availability of untaxed and inexpensive cigarettes. What is known with respect to the magnitude of illicit trade for Vietnam is produced primarily by the industry, and methodologies are typically opaque. Independent assessment of the illicit cigarette trade in Vietnam is vital to tobacco control policy. This paper measures the magnitude of illicit cigarette trade for Vietnam between 1998 and 2010 using two methods, discrepancies between legitimate domestic cigarette sales and domestic tobacco consumption estimated from surveys, and trade discrepancies as recorded by Vietnam and trade partners. The results indicate that Vietnam likely experienced net smuggling in during the period studied. With the inclusion of adjustments for survey respondent under-reporting, inward illicit trade likely occurred in three of the four years for which surveys were available. Discrepancies in trade records indicate that the value of smuggled cigarettes into Vietnam ranges from $100 million to $300 million between 2000 and 2010 and that these cigarettes primarily originate in Singapore, Hong Kong, Macao, Malaysia, and Australia. Notable differences in trends over time exist between the two methods, but by comparison, the industry estimates consistently place the magnitude of illicit trade at the upper bounds of what this study shows. The unavailability of annual, survey-based estimates of consumption may obscure the true, annual trend over time. Second, as surveys changed over time, estimates relying on them may be inconsistent with one another. Finally, these two methods measure different components of illicit trade, specifically consumption of illicit cigarettes regardless of origin and smuggling of cigarettes into a particular market. However, absent a gold standard, comparisons of different approaches to illicit trade measurement serve efforts to refine and improve measurement approaches and estimates.

    Crimes forecasting is an important area in the field of criminology. Linear models, such as regression and econometric models, are commonly applied in crime forecasting. However, in real crimes data, it is common that the data consists of both linear and nonlinear components. A single model may not be sufficient to identify all the characteristics of the data. The purpose of this study is to introduce a hybrid model that combines support vector regression (SVR) and autoregressive integrated moving average (ARIMA) to be applied in crime rates forecasting. SVR is very robust with small training data and high-dimensional problem. Meanwhile, ARIMA has the ability to model several types of time series. However, the accuracy of the SVR model depends on values of its parameters, while ARIMA is not robust to be applied to small data sets. Therefore, to overcome this problem, particle swarm optimization is used to estimate the parameters of the SVR and ARIMA models. The proposed hybrid model is used to forecast the property crime rates of the United State based on economic indicators. The experimental results show that the proposed hybrid model is able to produce more accurate forecasting results as compared to the individual models.

    The current study examined normative beliefs about aggression as a mediator between narcissistic exploitativeness and cyberbullying using two Asian adolescent samples from Singapore and Malaysia. Narcissistic exploitativeness was significantly and positively associated with cyberbullying and normative beliefs about aggression and normative beliefs about aggression were significantly and positively associated with cyberbullying. Normative beliefs about aggression were a significant partial mediator in both samples; these beliefs about aggression served as one possible mechanism of action by which narcissistic exploitativeness could exert its influence on cyberbullying. Findings extended previous empirical research by showing that such beliefs can be the mechanism of action not only in offline but also in online contexts and across cultures. Cyberbullying prevention and intervention efforts should include modification of norms and beliefs supportive of the legitimacy and acceptability of cyberbullying.

    While the Dangerous Drugs Act 1952 of Malaysia has been amended to take into account changing patterns of drug abuse and trafficking, it lacks provisions for the mandatory forfeiture of proceeds derived from drug trafficking. Nor do the general powers of forfeiture in the Criminal Procedure Code of the country extend to such proceeds. To meet further changing patterns of drug trafficking involving criminal syndicate leaders, who rarely incriminate themselves through overt and detectable acts, Malaysia has a bill in Parliament the purpose of which, when it becomes law, is to detain without trial, upon cogent evidence, persons who have been associated with any activity relating to or involving drug trafficking, and to prevent them from further committing drug crimes. In addition, serious thinking has been given to the possibility of adopting, within the constraints of the Malaysian Constitution, a law on forfeiture of the proceeds derived from drug trafficking. There are, in this respect, several problems to be resolved, such as the secrecy of bank accounts and taxpayers' returns, which might make it difficult to trace proceeds and to keep track of tainted money being remitted abroad, although it is believed that such problems could be overcome by domestic measures. A more serious problem is the lack of international co-operation for investigations to be carried out outside national borders to trace, seize, freeze and secure the forfeiture of the proceeds of drug crimes located abroad.

    The task of identifying firearms from forensic ballistics specimens is exacting in crime investigation since the last two decades. Every firearm, regardless of its size, make and model, has its own unique 'fingerprint'. These fingerprints transfer when a firearm is fired to the fired bullet and cartridge case. The components that are involved in producing these unique characteristics are the firing chamber, breech face, firing pin, ejector, extractor and the rifling of the barrel. These unique characteristics are the critical features in identifying firearms. It allows investigators to decide on which particular firearm that has fired the bullet. Traditionally the comparison of ballistic evidence has been a tedious and time-consuming process requiring highly skilled examiners. Therefore, the main objective of this study is the extraction and identification of suitable features from firing pin impression of cartridge case images for firearm recognition. Some previous studies have shown that firing pin impression of cartridge case is one of the most important characteristics used for identifying an individual firearm. In this study, data are gathered using 747 cartridge case images captured from five different pistols of type 9mm Parabellum Vektor SP1, made in South Africa. All the images of the cartridge cases are then segmented into three regions, forming three different set of images, i.e. firing pin impression image, centre of firing pin impression image and ring of firing pin impression image. Then geometric moments up to the sixth order were generated from each part of the images to form a set of numerical features. These 48 features were found to be significantly different using the MANOVA test. This high dimension of features is then reduced into only 11 significant features using correlation analysis. Classification results using cross-validation under discriminant analysis show that 96.7% of the images were classified correctly. These results demonstrate the value of geometric moments technique for producing a set of numerical features, based on which the identification of firearms are made.

    Forensic entomology applies knowledge about insects associated with decedent in crime scene investigation. It is possible to calculate a minimum postmortem interval (PMI) by determining the age and species of the oldest blow fly larvae feeding on decedent. This study was conducted in Malaysia to identify maggot specimens collected during crime scene investigations. The usefulness of the molecular and morphological approach in species identifications was evaluated in 10 morphologically identified blow fly larvae sampled from 10 different crime scenes in Malaysia. The molecular identification method involved the sequencing of a total length of 2.2 kilo base pairs encompassing the 'barcode' fragments of the mitochondrial cytochrome oxidase I (COI), cytochrome oxidase II (COII) and t-RNA leucine genes. Phylogenetic analyses confirmed the presence of Chrysomya megacephala, Chrysomya rufifacies and Chrysomya nigripes. In addition, one unidentified blow fly species was found based on phylogenetic tree analysis.

    Considering that crimes against animals such as illegal killing and cruelty have been alarmingly increasing and since burning is one of the common ways for disposing cadavers, ability to estimate minimum postmortem interval (PMI) using entomological data merits consideration. Chrysomya megacephala and Chrysomya rufifacies are common necrophagous species recovered from cadavers in many countries including Malaysia. Specific studies focusing on the oviposition and developmental patterns of both species on cadavers manifesting different levels of burn as described by the Crow-Glassman Scale (CGS) remain scarce. In four replicates, rabbit carcasses were burned to CGS levels #1, #2 and #3 by varying the amount of petrol used and duration of burning. Oviposition by C. megacephala and C. rufifacies was delayed by one day in the case of carcasses burned to the CGS level #3 (p<0.05) when compared with that of controls. Such delay in oviposition was not observed in the CGS level #1 and #2 carcasses. No significant differences (p>0.05) in the duration of development were found between control and burned carcasses. These findings deserve consideration while estimating minimum PMI since burning as a mean for disposing animal and human cadavers is gaining popularity.

    Introduction: Illegal immigrants refer to the migration of people into a country in ways that violates its immigra-tion laws. A stateless person is a person who is not considered as a national by any state under the operation of its law. Interestingly, many who are stateless have never even crossed an international border. The term illegal is very loosely used in places like Sabah where it is interchanged with statelessness. As of 13 November 2018, it was estimated that there are about 12 million stateless people in the world. This review seeks to understand the current demographic situation in Sabah along with the public health repercussions of this demographic change and also to look into the success stories from around the world along with the recommendations from United Nation in solving this matter. Methods: The method used is reviewing of literature of previous studies conducted on statelessness and illegals. Local as well as international studies were reviewed. The data base used was ProQuest. Results: This review identified that one third of Sabah’s population consists of non-locals and in the past 27 years, about half a million illegal immigrants have been deported from Sabah. These numbers pose major public health repercussions from the economic, crime and health point of view. The way forward involves incorporating the United Nation Action plan with the local requirements and settings. Despite challenges, Sabah is trying its best to curb this issue and the Public health repercussions through various initiatives. We have also identified that more public health actions can be taken to reduce the negative effects. Conclusion: Dealing with the stateless and illegals is a delicate matter and there is no one way to solve it. Every country and every state are unique therefore the methods used must be tailor made. This is not something that can be solved within a short period of time and therefore persistence and perseverance is very much needed to tackle this global issue.

    Forensic odontological examination of a disputed bitemark can furnish the police and the prosecutor with useful evidence to either implicate or exonerate a person in relation to a crime, on the basis that each person’s bitemark is as distinctive as his or her dentition. The aims of this article are (a) to evaluate the extent of which bitemark evidence is reliable as a proof of identification of a biter for the purposes of criminal investigation and prosecution in Malaysia and (b) to make the necessary recommendations (if any) for the purpose of improving the reliability of such evidence. Where a questioned bitemark is not sufficiently detailed, any findings made from its examination shall be highly unreliable and prejudicial. On the other hand, where a bitemark is sufficiently detailed, then any findings made from its examination may be reliable, provided that the forensic odontologists and other practitioners in the criminal justice system are professionally trained to handle the said bitemark. Therefore, police officers must be given a basic training in the field of forensic odontology so that they will be able to appreciate the evidential value of bitemark and contribute to the development of bitemark cases in Malaysia. The relevant authorities governing the dental practice in Malaysia should standardize the methodology and terminology used in bitemark examination and in the reporting of its findings so that confusion and inconsistency among the forensic odontologists are kept absolutely low. Finally, forensic odontologists must be given specialized training in bitemark examination so that the probative value of their findings can be improved.

    Individual identification is an important and challenging task in forensic investigation. Lip print on drinking glass or cigarette butt found at crime scenes may link to a suspect. The aim of this study was to determine the differences in lip print between sexes or races, differences in lip measurement between sexes or races and determine a way to estimate sex and race by using lip print or lip measurements for main races in Malaysia. A total of 134 subjects (67 males and 67 females) of Malay, Chinese and India were recruited from Universiti Kebangsaan Malaysia Campus Kuala Lumpur (UKMKKL), Malaysia. Lip prints were taken by using a lipstick and a transparent cellophane tape. Lip measurements were taken by using electronic digital callipers. Lip prints were classified according to Tsuchihashi classification. Statistical analysis indicated that there was a significant difference in lip print between sexes (p < 0.001) but not in races (p > 0.05). Width of oral opening and the height of lower lip both indicated significant differences between sexes (p < 0.001) while the height of upper lip and lower lip each indicated significant differences between races (p < 0.05). However, there was no significant interaction between sexes and races for all lip measurements. Formulae for sex and race determination were calculated with Classification Tree when there was significant difference between every comparison. Tables of accuracy percentage and performance evaluation for method in categorizing sex or race by using lip print or lip measurement were made. For validation of method in sex determination based on the formulae formed, accuracy in females is 90% and 65% in males. Therefore, overall percentage of accuracy in sex determination was 77.5%. This study can provide a preliminary idea about the use of lip prints in sex or race determination among Malaysian population.

    Objective: To study the demographic data of patients and the pattern of crime in the study group, to look at the outcome of assessment by psychiatrist on fitness to plea and insanity at time of offense and to assess association between the nature of crime with presence of psychopathology during the crime. Method: This is a retrospective study. All available case notes for 342 forensic admissions from January 2007 until March 2010 were reviewed. All related information on 135 patients that committed violent crime was taken for analysis. Result: Majority of patients were male, Malay, single, education up to secondary school and unemployed. Only 38% of patients had encountered psychiatric services, 20% had previous imprisonment and 49% had history of substance usage. In cases involving victims (87%), 64% the victims were known to the patient, 53% had hallucination or delusion or both at the time of crime and 90% was found to have some diagnosis of mental illness after psychiatrist assessment. Only 81% of formal forensic reports were available in the case note and it showed 94% were fit to plea and 82% were at sound mind at the time of offense. Conclusion: Substance abuse had high prevalence among the patient. Almost 2/3 never had any encounter with psychiatric services before the admission. Even with the high percentage of patient diagnosed with mental illness, they were still found to be fit to plea in court and are at sound mind at the time of offense

    With the rapid development of technology, mobile phones have become an essential tool in terms of crime fighting and criminal investigation. However, many mobile forensics investigators face difficulties with the investigation process in their domain. These difficulties are due to the heavy reliance of the forensics field on knowledge which, although a valuable resource, is scattered and widely dispersed. The wide dispersion of mobile forensics knowledge not only makes investigation difficult for new investigators, resulting in substantial waste of time, but also leads to ambiguity in the concepts and terminologies of the mobile forensics domain. This paper developed an approach for mobile forensics domain based on metamodeling. The developed approach contributes to identify common concepts of mobile forensics through a development of the Mobile Forensics Metamodel (MFM). In addion, it contributes to simplifying the investigation process and enables investigation teams to capture and reuse specialized forensic knowledge, thereby supporting the training and knowledge management activities. Furthermore, it reduces the difficulty and ambiguity in the mobile forensics domain. A validation process was performed to ensure the completeness and correctness of the MFM. The validation was conducted using two techniques for improvements and adjustments to the metamodel. The last version of the adjusted metamodel was named MFM 1.2.

    The incidence of benzodiazepine paradoxical reaction is uncommon. It may be implicated with crime as will be described in this case report. Method: We report a 37 year-old schizophrenia patient who was detained by the authority under Section 392/397 of Penal Code assaulting a lady using sharp weapon. He had history of illicit substance abuse and benzodiazepine dependence with significant history of aggression associated with benzodiazepine. Just prior to the incident, he took a significant amount of various types of benzodiazepine and suffered from amnesia of that event. During the time of the offense, he was in remission as far as schizophrenia is concerned. Result: He was under the forensic psychiatric care and observation at Hospital Bahagia Ulu Kinta (HBUK). He developed withdrawal symptoms of benzodiazepine in the ward. Conclusion: He was found by the expert team to be under the influence of benzodiazepine during the offence. The role of benzodiazepine and relevant factors leading to aggression will be discussed in this manuscript.

    This article attempts to present the trend among young offenders undergone Community Service Order (CSO) in Malaysia. An archival time series analysis approach was applied to identify the ethnicity, gender, type of crime and the total number of young offenders undergone CSO across Malaysia from 2009 until 2015. Relevant information was gathered after obtaining official statistic from the Department of Social Welfare Malaysia. In sum, a total number of 13,896 cases were reported in six-year duration throughout Malaysia. The highest number of cases were recorded in Wilayah Persekutuan Kuala Lumpur (545 cases). Moreover, an overall number of 2,989 young offenders have successfully undergone CSO from 2009 until 2015. The resultant data also indicated that majority of male young offenders undergone CSO are Malays in ethnicity (67.79%) and most of them have involved in property-related crime (47%). As an overall impact, the study provided implications to the concerned parties and key personnel such as welfare officers, criminal justice authorities and policies makers to reinforce the implementation of a community-based approach to recuperate young offenders who have involved in criminal activities.

    Flies from the family Calliphoridae, Sarcophagidae and Muscidae are usually found on human cadavers or animal carcasses. However, there are many other families of Diptera and Coleoptera that were found associated with animal carcasses, which have not been reported in Malaysia. In this paper, we report dipterans from the family Micropezidae: Mimegralla albimana Doleschall, 1856, Neriidae: Telostylinus lineolatus (Wiedemann 1830); Sepsidae: Allosepsis indica (Wiedemann 1824), Ulidiidae: Physiphora sp. and a beetle (Coleoptera: Hydrophilidae: Sphaeridium sp.) as opportunist species feeding on oozing fluid during the decomposition process. They did not oviposit on the pig carcasses, therefore, their role in estimation of time of death is of little importance. However, they could provide clues such as locality and types of habitats of the crime scene.

    Background: The "gender determination" which is an important human identification procedure not only helps in establishing the biological profile from skeletal and dental remains but also in facial reconstruction of unidentified victims.

    Aim: The aim of this study is to analyze predominant types of lip prints (cheiloscopy), accuracy of mandibular canine index (MCI) (odontometric), and facial index in the study population and to identify whether any correlation among the above parameters could help forensic dentistry in solving crimes.

    Materials and Methods: A pilot study was conducted in 100 individuals, 50 males and 50 females aged between 20 and 25 years. For each individual, the lip prints, MCI, and facial index measurements were recorded on the same day analyzed by two observers. All the analysis was done using SPSS version 14 assessed using t-test and Chi-square test.

    Results: Type II pattern of lip prints is observed as common pattern among male and female. There is no significant difference in Odontometric analysis. The mean value of facial index analysis in both genders shows highly significant.

    Conclusion: A large-scale study is required in order to validate our results to arrive at definitive results and value.
