Audio forgery is any act of tampering, illegal copy and fake quality in the audio in a criminal way. In the last decade, there has been increasing attention to the audio forgery detection due to a significant increase in the number of forge in different type of audio. There are a number of methods for forgery detection, which electric network frequency (ENF) is one of the powerful methods in this area for forgery detection in terms of accuracy. In spite of suitable accuracy of ENF in a majority of plug-in powered devices, the weak accuracy of ENF in audio forgery detection for battery-powered devices, especially in laptop and mobile phone, can be consider as one of the main obstacles of the ENF. To solve the ENF problem in terms of accuracy in battery-powered devices, a combination method of ENF and phase feature is proposed. From experiment conducted, ENF alone give 50% and 60% accuracy for forgery detection in mobile phone and laptop respectively, while the proposed method shows 88% and 92% accuracy respectively, for forgery detection in battery-powered devices. The results lead to higher accuracy for forgery detection with the combination of ENF and phase feature.
Objectives: To study the relationship between psychopathology and characteristics of offenders with schizophrenia. Methods: In this cross sectional study, 70 consecutive offenders with schizophrenia (aged 18-65) admitted to Hospital Bahagia Ulu Kinta within a six-month period were studied. Subjects’ psychopathology was assessed using Positive and Negative Syndrome Scale (PANSS). Results: Offenders against person group received treatment at later age (p=0.043) compared to against property and drug or firearm-related offenders groups. Offenders in drug or firearm-related group had significantly higher PANSS negative scores (p=0.015). Unsound mind at the time of offense was significantly associated with high PANSS positive scores (p=0.011) and offenders against person or property groups (p=0.004). Conclusion: Offenders against person had a significantly later age of treatment and probably onset of illness. Unsoundness of mind was significantly associated with positive symptoms and more frequently reported among offenders against person or property. Offenders in drug or firearmrelated
group were significantly associated with negative symptoms.
Rapid growth in world trade has enabled transnational criminal networks to conceal their contraband among the 1 billion containers shipped worldwide annually. Forensic methods are needed to identify the major cartels moving the contraband into transit. We combine DNA-based sample matching and geographic assignment of tusks to show that the two tusks from the same elephant are often shipped by the same trafficker in separate large consignments of ivory. The paired shipments occur close in time from the same initial place of export and have high overlap in the geographic origins of their tusks. Collectively, these paired shipments form a linked chain that reflects the sizes, interconnectedness, and places of operation of Africa's largest ivory smuggling cartels.
The main goal of the present research is to examine socio-ecological hypothesis on apology and compensation. Specifically, we conducted four studies to test the idea that an apology is an effective means to induce reconciliation in a residentially stable community, whereas compensation is an effective means in a residentially mobile community. In Studies 1, 2a, and 2b, American and Japanese participants (national difference in mobility; Study 1) or non-movers and movers (within-nation difference in mobility; Studies 2a and 2b) imagined the situations in which they were hurt by their friends and rated to what extent they would be willing to maintain their friendships upon receipt of apology or compensation. The results showed that compensation was more effective in appeasing residentially mobile people (i.e., Americans and movers) than stable people (i.e., Japanese and non-movers), while apology was slightly more effective appeasing residentially stable people than residentially mobile people (significant in Study 1; not significant in Studies 2a and 2b). In Study 3, by conducting an economics game experiment, we directly tested the hypothesis that mobility would impair the effectiveness of apology and enhance the effectiveness of compensation. The results again partially supported our hypothesis: In the high mobility condition, compensation increased one's willingness to continue the relationship with the offender, when compared to willingness in the low mobility condition. The importance of socio-ecological perspective on the forgiveness literature is discussed.
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.
Consent is defined as the “voluntary agreement to or acquiescence in what another person proposes or desires”. In the context of medical practice it is now universally accepted that every human being of adult years and of sound mind has the right to determine what shall be done with his or her own body. Informed consent is now a central part of medical ethics and medical law. There has been a change in the public’s expectations of their role in medical decision making. The paternalistic approach by doctors is no longer acceptable. Today the patient has the right to receive and the doctor the obligation to give sufficient and appropriate information so that the patient can make an informed decision to accept or refuse a treatment option. This has led to higher standards of practice in the process of informed consent taking. Consent taking is both a legal and moral requirement. Failure to comply with standards of practice can result in criminal prosecution, civil litigation or disciplinary action by the relevant professional authority. Consent taking is a process and not merely a one-off affixation of the patient’s signature on consent form. It involves a continuous discussion to reflect the evolving nature of treatment from before the treatment is given to the post-operative or discharge period. The regulatory authorities in many countries have established standards for consent taking which would include the capacity of the patient, the person who should seek consent, the information to be provided and the necessary documentation.
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
Objective: This case report aims to discuss the diagnosis of mental retardation as insanity defence in a crime offender. Methods: We report a gentleman who committed murder and rape 9 years ago, and currently being treated at a mental institution. Results: Patient was certified to have mental retardation, and was pleaded on the defence of unsoundness of mind because he had defect of reason at the time of alleged offence. Conclusion: Mental retardation does fulfil the McNaughton’s rule. Unsoundness of mind becomes the insanity defence even for murder under section 84 of the Penal Code.

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.
The datasets in this article provides supplementary information related to: (1) demographic profile of young offenders and (2) perpetrator experience in committing a crime. A quantitative approach based on a cross-sectional survey design was employed to collect data among 306 young offenders undergoing Community Service Order initiated by the Malaysian Social Welfare Department. The resultant data were analysed descriptively using Statistical Package for the Social Sciences (SPSS). The result stipulates that the majority of respondents are consist of male young offenders aged 20 years old, Malays, single in marital status, and unemployed. Based on the crime involvement aspect, the result indicates that young offenders involved in stealing (26.1%), does not carry any weapons while committing a crime (50.0%), and entangled in criminal activity due to peer influence (40.0%). Moreover, unfavorable luck contributes to the failure in executing crime (52.6%) which subsequently leads them to be arrested by the police (52.0%).
Apart from environmental and social factors, psychological traits is largely linked with criminal and delinquent behaviour. The purpose of this article is to review four critical psychological traits of individuals that may lead to criminal behaviour in a nutshell. Methods: An archival research methodology was employed in this study where relevant search for literatures on these four psychological traits was made across search engines such as Google Scholar with relevant articles selected for this review. The literatures were microscopically reviewed in order to demonstrate the linkage between psychological traits and criminal behaviour. Results: Four psychological traits: personality trait, low selfcontrol, aggression behaviour, and cognitive distortion were chosen to address such linkages. All these four traits were discussed thoroughly in relation to crime and criminality contexts. Conclusion: It is crucial to understand the role of these traits and in-depth understanding of each psychological trait with relation of criminal behaviour offers an opportunity to the public at large to expand their knowledge on the importance of practicing and equipping oneself with healthy psychological traits to hinder from criminal and delinquent acts.

A review of the criminological literature indicates that some personality traits appear to develop and shape violent criminal behaviour. With this in mind, the present study was aimed to examine the personality profiles of Malaysian male murderers utilising the Alternative Five Factor Model (AFFM) constituting five personality traits: Activity, Sociability, Aggressiveness-Hostility, Impulsive Sensation Seeking, and Neuroticism- Anxiety. Methods: The present study was an observational cross-sectional study using a guided self-administered questionnaire. Items representing the five personality traits were assessed through the Malay version of Zuckerman-Kuhlman Personality Questionnaire-40-Cross Cultural Questionnaire (ZKPQ-M-40-CC). 71 male prisoners convicted of murder who are incarcerated in 11 Malaysian prisons were recruited. Descriptive item analyses were carried out to elicit the level of responses for each item in the ZKPQ-M-40-CC. Furthermore, the descriptive personality profiles using mean scores were performed. Results: The results indicated that the mean score of Activity (29.35, SD = 5.66) was higher than other personality traits. The mean score of Impulsive Sensation Seeking (21.65, SD = 6.48) and Aggressiveness-Hostility (21.65, SD = 6.48) were higher than the mean score of Neuroticism-Anxiety (17.96, SD = 5.51). Among the participants, 56.3% of them scored above the mean score (M = 26.54) for Sociability personality traits, which was the highest compared to other personality traits. 53.5% of the murderers scored equal or above the mean score (M = 6.48). Correlations among the five personality traits indicated several significant associations. Conclusion: In conclusion, the present study successfully identified the personality profiles of Malaysian male prisoners convicted of murder.
Objective: Pritchard Criteria are adopted in a Malaysian criminal-justice system while assessing fitness to plead. There is limited data on the reason of unfitness to plead for female offenders in Malaysia.
Methods: A case series of five patients hospitalized to Hospital Bahagia Ulu Kinta, Malaysia due to unfitness to plead was presented and discussed.
Result: The offences include three homicides, one assault, and one stealing. All of them were diagnosed to have schizophrenia with prominent looseness of association. Four of them subsequently treated as Treatment-Resistant Schizophrenia (TRS) with a minimal response toward clozapine.
Conclusion: Looseness of association may be a contributing factor for unfitness to plead among Malaysian female offenders, which can result in indeterminate hospitalization. This should be confirmed in a larger prospective study.
Introduction: Psychotherapy is a form of treatment intervention targeting problematical human behaviour, emotion, and cognition using various psychological techniques and approaches. In Malaysia, the application of psychotherapy in ameliorating criminality among forensic populations is developing and evidence shows that some therapies like Cognitive-Behavioural Therapy and Reality Therapy have been practiced in many correctional institutions.
Objective: This paper aims to review the role of psychotherapy for help in correctional settings as a means to ameliorate criminal behaviour and reduce recidivism rates.
Method: An archival research was utilised, where articles and books regardless of the year of publication from different countries, including Malaysia were examined. Several keywords were used for the purpose of retrieval of related articles.
Results and Discussion: Three different approaches of psychotherapies, i.e. Behavioural Therapy, Cognitive Therapy and Cognitive-Behavioural Therapy and their principles and effectiveness in rehabilitating the forensic populations were elaborated in this review. The principle behind the effectiveness of the psychotherapy was different, and this influences the choice of treatment that should be used in dealing with the forensic populations.
Conclusion: Forensic populations have rights to obtain treatment, and the choice of therapy has to be relevant within the context of cost-effectiveness to ensure optimum effectiveness in ameliorating criminal tendencies.
This study examined different types of symptoms of problem behaviours among juvenile offenders. Various symptoms of problem behaviours such as social problem, thinking problem, attention problem, rule-breaking behaviour, and aggressive behaviour can be predicted among young juvenile delinquents. There were 404 juvenile offenders participated in the study, consisted of 280 males and 124 females. All respondents convicted with seven different offenses. Prior to that, three research questions were developed: 1. Are there differences in the symptoms of problem behaviours among different types of juvenile offenders? 2. Are there gender differences in the symptoms of problem behaviours among young offenders? 3. Are there any age differences in the symptoms of problem behaviours among juvenile offenders? The results showed there were different symptoms of problem behaviours among young offenders. Gender differences profile also showed mean differences in each symptom of problem behaviours among juvenile offenders. One-way ANOVA results showed significant differences in thought problem F (7) = 2.748, p< .01 and attention problem F (7) = 25.948, p < .01 among different types of delinquent behaviours. Moreover, t-test results revealed that gender differences were significant in social problem; t (402) = -2.710, p
Ex-offenders are facing major challenges after their release to survive in the community. Among the challenges are stigma from the community, physical and mental health issues, financial problem because of unemployment and loss of significant others. They need to be guided to manage issues regarding employment, family, interpersonal relationship, and self-management. This article will discuss issues and barriers for ex-offenders to return to work or join the workforce. Past findings showed that ex-convicts and ex-drug addicts are still facing with barriers which withhold them from joining the job market. They frequently become the victims of rejection, bias, being bullied, and being segregated by co-workers. Barriers in employment may also be rooted from themselves, such as attitude problem, bad work culture, aggressive personality, and disciplinary issue. Thus, effective programmes and interventions need to be implemented for ex-offenders to increase their employability, and hence joining the community.
Short tandem repeat (STR) typing continues to be the primary workhorse in forensic DNA profiling. Therefore, the present review discusses the prominent role of STR marker in criminal justice system. All over the world, deoxyribonucleic acid (DNA) profiling provides evidence that may be used to convict criminals, as an irrefutable proof of wrongful convictions, invaluable links to the actual perpetrators of crimes, and could also deter some offenders from committing more serious offences. Clearly, DNA profiling tools have also aided forensic scientists to re-evaluate old cases that were considered closed as a result of inadequate evidence. In carrying out this review, a comprehensive electronic literature search using PubMed, ScienceDirect, Google Scholar and Google Search were used, and all works meeting the subject matter were considered, including reviews, retrospective studies, observational studies and original articles. Case reports presented here, further demonstrates the crucial role of forensic DNA profiling in mitigating and providing compelling evidence for the resolution of crimes. For case report 1, there was a 100% match between the DNA recovered from the items found in the crime scene, and the suspect's DNA sample collected via buccal swab following 15 STR loci examination. Case report 2 further highlights the indispensable contribution of DNA database in solving crime. Therefore, it has become very necessary for developing countries like Nigeria to develop a national DNA database and make policies and legislatures that will further expand and enable the practice of forensic genetics, particularly DNA profiling.
This paper investigates the pattern of sexual offence cases attended at the One Stop Crisis Center (OSCC) of the Accident and Emergency Department, Hospital Universiti Sains Malaysia (HUSM), Kelantan. A total of 439 reported sexual offence cases were examined over a period of 4 years from 2000 to 2003. Sexual offence constituted by male partner or boyfriend in 18.9%, by relatives in 27.3% and by "others" in 53.8% of cases. Only 0.7% of victims did not attempt to lodge a police report. There is a significant relationship between occupation and the risk of experiencing sexual violence. Students were mostly targeted by the perpetrator throughout the study period. Among the offences, rape cases were the highest in number, among those who attended at the OSCC, HUSM with a total of 72.7%; followed by 27.3% of incest; 26.4% of child sexual abuse; 4.8% of sodomy and lastly 1.6% of gerontophilia cases. Only 70% of the specimens obtained from sexual offences victims were sent for laboratory analysis. The result remained negative in 82.4% specimens and thus the laboratory analysis result is merely functioning as a supportive evidence for sexual offence cases attended at OSCC. The studies showed that most of the sexual assault perpetrators were known to the victims. The place of crime was also known to the perpetrators. Health sectors of various levels should be working in conjunction to promote a societal changes to improve more of the women's right and thus to reduce the violence crime.
The population of incarcerated sex offenders in Malaysia is steadily growing. Objective: This is a descriptive study to look at what clinical and developmental characteristic are present amongst the sex offenders in Malaysia, which could be possible mitigating factors. Methods: Data was collected from offenders located in 3 prisons where the offenders are held. Results: a total of 147 prisoners participated in the study. Slightly more than half of the victims were below the age of 18, of which 10% were below the age of 12. Three quarters of offenders were thirty years and older, while 12% were below 18 years. However their problems begun much earlier in their life with 50% of the offenders reporting that they had difficulties in their
primary support group, resulting in them feeling their families were less expressive, their parents were distant and unsupportive.29% of the offenders had not lived with their parents from the age of 16. More than half of the offenders reported academic, behavior and developmental difficulties; they reported losing interest in their studies and were struggling during their schooling days. 43% had history of aggressive behaviour during their adolescent years and 76% had peers who often indulged in risky behaviors. 85% of the offenders were Muslim. 40% made the criteria of Attention Deficit Hyperactive Disorder and conduct disorder while a quarter were diagnosed with having personality disorder. Slightly more than half of the offenders had alcohol and drug-related problems, 36% had history of previous crimes, mainly drug and theft offence. Conclusion: The findings show that the sex offenders are indeed a heterogeneous group with pervasive familial, behaviour, academic and social problems which are possible risk that can be identified early in the lives of offenders.
