This trace evidence can be used as proof of contact to narrow down the search in a criminal investigation. The identification and differentiation of samples with similar composition and the same hue can be a difficult task for the investigator. </span></span></span></span></p> <p><span style="font-family: Times, serif;"><span style="font-size: small;">In the present work, the scope of Attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy for discriminating shoe polish samples of 15 different brands is investigated in combination with chemometric tools that is principal component analysis. The discriminating power of visual analysis is 99.04 %, while in principal component analysis it is 98.09 %, which is highly significant. The blind test is carried out with unknown samples to the analyst, to predict their respective sample source. Intra-brand variation, homogeneity and the effect of different substrates on sample analysis are also studied. The reported method provides considerable results for the identification and differentiation of shoe polish samples of different brands. The stains on substrates could be identified and linked to their parent source as well.</span></span></p> Sweety Sharma Spriha Sharma Rajinder Singh Copyright (c) 2020-06-15 2020-06-15 2 1 04 15 10.26735/KAMK2533 Study of Fatal Firearm Cases in Allahabad Region, India <table width="697" cellspacing="0" cellpadding="7"><colgroup><col width="681"> </colgroup> <tbody> <tr> <td valign="top" width="681"> <p align="justify"><span style="color: #000000;"><span style="font-family: Adobe, serif;"><span style="font-family: Times, serif;"><span style="font-size: small;"><strong>Abstract</strong></span></span></span></span></p> <p align="justify"><span style="color: #000000;"><span style="font-family: Adobe, serif;"><span style="font-family: Times, serif;"><span style="font-size: small;">This study was done to assess the pattern of firearm injuries in Allahabad amongst medicolegal autopsies in the mortuary of Swaroop Rani Nehru Hospital, MotiLal Nehru Medical College, India.

A Borewell which is a digging structure, is created by digging, driving, boring, or drilling the ground to access groundwater from underground aquifers. When these borewells don’t fetch enough water they are abandoned without taking proper measures to seal them. Children might get accidentally stuck and trapped in the tubing or the hole of the borewell through which they are unable to extricate themselves. Due to this, if immediate rescue is not done, chances of survival of the little victims get diminished. </span></span></span></span></p> <p align="justify"><span style="color: #000000;"><span style="font-family: Adobe, serif;"><span style="font-family: Times, serif;"><span style="font-size: small;">Cases of children falling in borewells were studied from year 2006 to 2016. Data were reviewed from available literature, national crime record bureau of India, the news published in press media either as hard print, e- news, television etc. A total of 43 incidents of victims who had fallen in borewells were studied. Most of these cases were of children below 6-years with male preponderance. In most of the cases, victims died due to asphyxiation due to wedging of the body in the narrow space of the borewell. In few cases (rather 2 cases) there was water in the borewell which may have drowned the victims. </span></span></span></span></p> </td> </tr> </tbody> </table> Nilesh K.

Among such substrates, blood stained fabrics are one of the most commonly encountered evidence. Analysis of bloodstains on fabrics is restricted due to interference of fabric dyes, color of fabric which hampers visual identification, and limited sample quantity. Over the years, a plethora of research has been conducted to analyze recovered blood traces, however, the methods employed are limited by factors such as sample destructibility, chronophagus processing, and vulnerability to false positive results. To circumvent the aforementioned limitations, use of ATR FT-IR spectroscopy has surged as a non-destructive and reliable tool for the detection of traces of blood and other body fluids on fibers. In the present study, an attempt has been made to detect traces of blood in fibers of different types and colors using ATR FT-IR spectroscopy. The obtained results unequivocally concluded that by using ATR FT-IR spectroscopy blood can be successfully detected even on a single fiber through characteristic peaks positioned at 1650 cm</span></span><sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">-1</span></span></sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;"> and 1543 cm</span></span><sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">-1</span></span></sup><span style="font-family: Times New Roman, serif;"><span style="font-size: small;"> corresponding to amide I and amide II.

Strox is a popular synthetic cannabis in Egypt that consists of smokable herbal products laced with unidentified synthetic cannabinoids. Unfortunately, threats from the escalating use of Strox in Egypt are increasing, which is a challenge for medical and legal systems. Acute Strox intoxication manifested by acute toxic psychosis and severe cases could develop cardiovascular instability and fatal coma. Strox-related toxicity could be attributed to THC analogs and anticholinergic agents along with the presence of additives such as ketamine. Limited knowledge considering exact Strox ingredients makes its identification in biological samples using standard toxicology impossible. In 2018, Egyptian law criminalized the usage of five THC analogs that are rapidly followed by alteration of Strox constituents by its manufacturer using non-prohibited cannabinoids to escape legal prohibition. Therefore, comprehensive studies are needed to identify common Strox constituents with subsequent successful detection. Moreover, the amendment of the law is essential to include any substances that have cannabis-like actions in the schedules of a prohibited substance.</span></span></span></span></p> Zahraa K.

The quantity of CO concentration inhaled determines the level of damage which is proportional to either morbidity or mortality. The euphoria and rapidity of the mechanism of action of CO ranked it as a deleterious gas that could cause reparable to irreparable damage within a short interval. Disguised CO intoxication death is quite difficult to differentiate from that of accidental acute CO intoxication using autopsy findings. This gap is now utilized in committing heinous crimes. Postmortem use of blood is not practicable in most toxicological investigations due to fermentation and putrefaction. This has led to the use of vitreous humor in postmortem analytical toxicology. The dilemma in discriminating death truly resulting from CO intoxication from that of disguised (postmortem) CO intoxication is the quest of this study. This review elaborately takes a critical look at the literature relating to the subject of discourse with the view of drawing salient points that could be of critical importance in forensic science. A thorough review of the picture of vitreous chemistry resulting from acute CO intoxication was almost exhaustively analyzed based on the various perspectives found in the literature and other documents of importance.</span></span></span></span></p> ENI-YIMINI S.

Reliable results and valid analytical data are an essential requirement for proper interpretation of forensic toxicology cases, especially when evaluating scientific studies and daily routine work, and when presenting any toxicological findings as criminal evidence.</span></span></span></span></span></p> <p align="justify"><span style="color: #000000;"><span style="font-family: Calibri, serif;"><span style="font-size: small;"><span style="color: #222222;"><span style="font-family: Times, serif;">In contrast, the results of unreliable analyses can be disputed in court and can also lead to unfair legal judgments against the defendant, or can result in wrong treatment in cases of rehabilitation of patients. In order to establish strong evidence and make a correct decision, the lab is asked to give high quality data that are based on reliable analytical methods. For that reason, all new analytical methods used in forensic toxicology including the clinical diagnosis of causes of death require careful care during the development of the analytical method and during its application. This is also an urgent need in the context of quality management and accreditation, especially as those issues have become increasingly important in the science of poisons and drug analysis in recent years.</span></span></span></span></span></p> Abdulsallam Bakdash Jihad Al-Qudsi Huda M.

For this purpose, a sample of 184 prisoners (149 males, 35 females)<br>as well as 240 normal participants (male 120, female 120)were selected. The prisoner cohort group selected for the study was convicted for the following offences: Section 302 IPC, 307 IPC, 376IPC, 363-364 IPC, 366 IPC, 323-26 IPC. Galton’s system of classification was followed to classify various dermatoglyphic patterns. In the male criminal cohort group, the overall frequency of loop patterns (56.51%) was maximum compared to the frequency of whorls (38.79%) and arches (4.7%), while males in the control group exhibited the highest frequency of whorls (48.25%) followed<br>by loops (47.67%) and arches (4.08%).

The frequency of arches was lowest in both the hands with higher fractional percentage in the radial side (thumb and index finger) of distoproximal axis as compared to ulnar side (ring finger and little finger) in both the groups. Pattern intensity index (13.40 vs 13.05),<br>and furuhata’s index (69.35 vs 68.47) of the criminal males and females were found to be comparable, but the Dankmeijer’s index (12.11 vs 18.93) of the male criminals was lower than their female counterparts, thereby indicating a higher occurrence of arches in the female criminal cohort group.</p> Maninder Kaur Mankamal kour SettingsPreet Kamal Jatinder Kaur Copyright (c) 2019 Arab Journal of Forensic Sciences & Forensic Medicine 2019-12-31 2019-12-31 2 1 1403 1411 10.26735/16586794.2019.030 Postmortem Toxicology Data of Autopsied Cases in the Northern Border Province, Saudi Arabia: A Six-Year Retrospective Study <div> <p>Autopsy remains the most reliable tool to study mortality causes.This project was conducted to study toxicological findings in relation to gender, age, manners and causes of death among autopsied cases from 2013-2018 in the Northern Border province of Saudi Arabia. All police, hospitals, toxicology laboratory and autopsy reports related to the autopsied cases within the period of the study were revised. Among 908 autopsied cases during the study period, 144 autopsies (15.8%) showed positive toxicological findings (136 males (94.4%) and 8 females (5.4%)). Positive toxicological findings were significantly more common in cases aged 20-40 years (p&lt;0.0001) without a significant gender difference (p=0.116). The commonest toxicological finding was alcohol 55 cases (6.5%) followed by cannabis in 27 cases (2.9%), while 19 cases (2.1%) showed carboxylhemoglobin ≥10%. Most deaths with positive toxicological<br>screens (98 cases (68.1%)) were reported to be accidental. Six cases were recorded as carbon monoxide poisoning (COP), 3 cases were recorded as alcohol toxicity, and 2 cases were registered as hypertensive induced brain haemorrhages. Brain haemorrhages and aspiration pneumonia were reported among deaths related to alcohol,<br>while intraventricular brain haemorrhage was the cause of death in amphetamine deaths. Cherry red hypostasis and pulmonary edema were found among COP deaths. In conclusion, positive toxicology data were found in a considerable percent of autopsied cases, and they can contribute directly or indirectly to identifying the cause of death. Hence,<br>toxicological screening is mandatory in all suspected deaths and screening should not be neglected in cases with absent suggestive autopsy findings.</p> </div> Tarek Abdelraouf Ekramy Elmorsy Mohamed ElHafez Amira Alshaman Hanaa M.

The present study aims to investigate the remaining fraction of kerosene hydrocarbons impregnated on four kinds of textiles (nylon, polyester, wool and cotton). The volatile fraction was collected by SPME on non-burnt and<br>burnt samples at successive times (0, 0.5, 1, 2 and 4 h.), then analyzed by GC-MS. Among the 27 characteristic compounds identified in kerosene, aromatic hydrocarbons were the predominant components, but their&nbsp;evaporation was faster than alkanes in unburnt textiles. Also, in the case of non-burnt samples, the total amount of kerosene residues was higher in synthetic tissues than in natural materials. After burning the different kinds of impregnated textiles, 22 hydrocarbons were detected with a decreasing amount over time, while the concentration of linear alkanes remained higher during the sampling time. All the partially burnt samples displayed much less kerosene&nbsp;residues than in the same unburnt samples. Unlike the non-burnt samples, the profile of kerosene amount as function of time was<br>very similar on the four investigated kinds of fabrics after burning. These results and the proposed procedure should help forensic investigators in the field of fire debris analysis, in arson cases.</p> Abdulrhman M.

Intersections were prepared using an inkjet printer, laser printer, and writing instruments on copier paper. About 1cm2 of intersection was cut using scissors and mounted to the probe stage of the SEM using double-sided tape. Each sample was analyzed at different operating parameters. The results were evaluated on the basis of continuity and iscontinuity of strokes at intersection point. It was possible to determine the correct sequence of printer strokes versus other writing instruments’ strokes; inkjet printer stroke versus fountain and pilot pen ink stroke; however, inconclusive results were obtained in the case of inkjet printer strokes versus ball point pen and gel pen ink&nbsp;strokes. The ffectiveness of this technique was determined by analyzing the exact sequence of blind samples. An SEM could be used as mplimentary tool with other optical methods to examine the sequence of strokes.</p> Komal Saini Rajshree Rathore Ravinder Kaur Tarun Sharma Shabnam P.

However, the United Nations Office on Drugs and Crime (UNODC) classified kratom,&nbsp;<em>Mitragyna speciose</em>, as a plant-based New Psychoactive Substance (NPS) that must be monitored worldwide, due to increasing reports of abuse. Many countries, including the Philippines, do not put restrictions on the said plant species including its major psychoactive drug, mitragynine. Under this prevailing provision, a research exploration was carried out to determine the distribution of kratom trees,<em>&nbsp;</em>locally known as “mambog”, in the Philippines and authenticate species identity of collected specimens through chemical determination of mitragynine and DNA analysis.</p> <p>Various samples, specifically leaves, twigs, barks and roots,<strong>&nbsp;</strong>from claimed kratom species in selected regions of Luzon and the Mindanao Islands of the Philippines were sampled and preserved accordingly before subjecting them to instrumental analysis using Gas-Chromatograph Mass Spectrometer (GC-MS) and DNA barcoding.</p> <p>During the field exploration, it was well documented that claimed kratom trees are mostly present in wetland areas at low altitudes, and sometimes co-exist with local bangkal (genus&nbsp;<em>Nauclea</em>) trees. Interestingly, while locals identified some of the collected species as kratom through botanical assessment, mitragynine was not detected in some selected sampling sites. Remarkably, among tree parts collected, only leaves and twigs<strong>&nbsp;</strong>showed evidence of mitragynine suggesting further disparity among kratom tree parts.&nbsp;</p> Atty. Severino P.

Several researches have been developed to estimate wound age, unfortunately with limited success. The aim of the present work was to evaluate the efficacy of Cluster of Differentiation 14 (CD14) as a reliable marker for estimating wound age. The study was conducted on forty bodies of victims with different types of wound and known infliction time. Skin samples were obtained during autopsy from the center of the wound. Sections from samples were histologically examined by H &amp; E stain. Immunohistochemical staining was done using CD14 antibody and the staining density was evaluated semi-quantitatively. There was a statistically significant relation between wound&nbsp;age and percentage of CD14 expression. Expression of CD14&nbsp;was 61.81±6.55 % in specimens from wounds aged less than 12&nbsp;hours. It increased till reaching its maximum (96.40±3.78 %) for&nbsp;wounds aged between 1-3 days. Then it decreased dramatically to&nbsp;14.80±3.49 % in wounds older than 3 days.&nbsp;CD14 is proved to be a reliable marker for estimating wound&nbsp;age. It gave best results in wounds aged between 1-3 days with an&nbsp;overall accuracy of 100%. Accordingly, it can be used to determine wound age in medicolegal practice.</p> Azza A. Fouad Fatma M. M.

In a case of incest between a brother and his married sister, a paternity test and a<br>statistical analysis were performed at the laboratories of the Paternity and Kinship Division of the Medico-legal Directorate Baghdad, Iraq. Blood samples were taken from the concerned subjects in this case (newborn baby, mother, alleged father, and the husband) and placed on FTA cards. DNA extraction was done using Chelex®, then the<br>amplification of extracted DNA was carried out using an AmpFlSTR® Identifiler kit. PCR products were run with a 3130xl Genetic Analyzer, and the data were analyzed with Gene-Mapper ID® Analysis Software V.3.2 software.The analysis of DNA profiles using 15 loci as well as the statistical analysis for calculating the paternity index confirmed the allegation of the brother-sister incest, since the baby inherited all the obligate alleles from the alleged father (suspected brother). With a 99.9998% probability of paternity, these results showed that even in the case of brother-sister incest, paternity could be proved using 15 DNA locus with a high rate of certainty.</p> Nadia F.

With the introduction of new banknotes (announced after demonetization) having advanced and exclusive security features, it is the need of the hour, especially for a forensic Scientists, to have an idea about these new features and the various methods to examine these features. Results presented in this paper are based on examination and comparison of original and suspected fake 2000 rupee Indian currency banknote utilizing physical examination methods and techniques such as physical, microscopic, digital image processing, etc. During the examination of original 2000 rupee banknote, it was found that some security features of this banknote are unique &amp; exclusive and could not be forged by counterfeiters. Counterfeiter<br>could only imitate most of the visual features of banknotes but some specific security features like OVI print, UV-fluorescent print, micro letters, etc. which are placed on all over the substrate of original banknote, could not be mimicked. However, imitation of the visual features, can at times deceives the public in general. The present case study presents a methodology which will be very useful and informative in assisting the forensic community in examination of fake currency banknotes and for future studies.</p> Ritika Verma N.

Traditional means of proof lack the necessary means to identify the offender as a result of them using modern methods to commit their crimes.</p><p>Criminal justice systems have relied upon modern criminal investigation techniques such as ear prints in identifying perpetrators. However, the use of such techniques as criminal evidence raises problems as to the accuracy of the identity of the individual and may prejudice human rights guaranteed by the constitution.</p><p>In this study, we attempted to identify the role of ear prints as evidence and their evidential weight before the criminal courts, and the reliability of them as evidence before the criminal judge in various crimes.</p><p>The study revealed that there is no law regulating the use of ear prints as criminal evidence. There is also a lack of agreement among specialists on the accuracy of their results, which did not reach 100%. This works in favor of the accused, based on the principle that he is innocent until proven guilty. This also shows that ear prints alone cannot be used to prove guilt, because they do not provide certain and clear proof; any conviction must be based on certainty. They need to be supported by other means of proof. However, ear prints are suitable for acquittal or recognition of victims of crime or unknown persons in the event of disasters or newborns, etc.</p><p>Ear prints are not suitable as criminal evidence in crimes with prescribed Islamic sharia punishments, because they contravene the rules of proving guilt prescribed in Islamic law.</p> Mashaallah O.

The problem of money-laundering has become a phenomenon that alarms states and individuals because of its serious effects in all aspects of political, economic and social life, as well as in its sources of support, as it is fueled by crime in all its forms. The crime of money-laundering has assumed an advanced rank for crime patterns in light of the development of information technologies and means<br>of communication. Therefore, states have sought to establish laws and resolute procedures to prevent the spread of this phenomenon. The judiciary has a duty to bring an end to a number of crimes.

However, the associated secondary epidermal<br />creases of fingerprints, fingerprint white line count (FWLC), has<br />received less attention within the forensic community. This study<br />was conducted with an aim to determine the potential of FWLC in<br />sex inference among adult Nigerians.<br />A cross sectional study was carried out with 150 males and<br />150 females with age range of 18-30 and 18-33 years, respectively.<br />Live scanner (Digita persona, China) was used to capture the plain<br />fingerprint for FWLC. Mann Whitney, Kruskal Wallis and logistic<br />regression analyses were employed for determination of digit<br />variation (based on side and type), sexual dimorphism and prediction<br />models, respectively. Likelihood ratio and posterior probability<br />were used to determine the favour odd for sex inference from<br />FWLC.<br />A significant higher mean value of FWLC was observed in females<br />(2.24 ± 2.03) compared to males (0.85 ± 1.29). Absence of<br />white line was indicative of male origin in all the digits except for<br />left index digit (favor odd of 0.72 for females and 0.29 for males).<br />However, FWLC from 5 to 11 were more likely to be of female<br />origin. The best discriminator of sex was the left FWLC with a<br />percentage accuracy of discrimination of 72%. The percentage contribution<br />of the left FWLC in the discrimination of the sexes was<br />observed to range from 23.0 to 30.20%.<br />The FWLC was found to be a potential predictor of sex among<br />adult Nigerians of Hausa ethnic origin.</p> Lawan H.

Although nowadays<br />there are a variety of methodologies focused on the analysis of inks, the<br />combination of non-destructive nature of Hyperspectral Imaging (HSI)<br />coupled with the multivariate chemometric technique has received little<br />attention.<br />In this study, forty-five (n = 45) gel pen inks of three different colours<br />i.e. blue, red and black of five different brands were analysed using<br />HSI with the idea of classifying them according to the brand.<br />In terms of discriminating similar coloured components between<br />samples, this was achievable only on the basis of the % reflectance<br />spectra. However, arguably, there was sufficient evidence to suggest<br />that it may be possible to discriminate the samples using chemometric<br />of Principal Component Analysis (PCA). A 2-D score plot from PCA<br />analysis was enough to characterise the samples into five clusters.<br />The synergy of complementary information provided by PCA narrows<br />matching possibilities (in terms of classification) for forensic investigations<br />involving ink analysis.</p> Muhammad N.

Deaths commonly arise during the manufacturing<br />process and improper handling of chemicals for<br />fireworks.<br />Here, we would like to highlight a rare case in which a<br />12-year-old child sustained a head injury due to a cracker<br />blast, which resulted in a depressed fracture over the vault of<br />her skull. In this paper, we tried to emulate the same pattern<br />of fracture on a human skull bone experimentally using the<br />same type of cracker which caused the injury.<br />This was done to give us an insight as to whether the<br />cracker was powerful enough to produce a fracture and to<br />rule out suspicion of blunt force trauma due to a weapon on<br />the head. The subsequent explosion caused by the blast produced<br />a distinctly similar pattern of fracture in comparison to<br />the fracture observed in our case.<br />The study also highlights the dangers of country-made<br />crackers handled by children.</p> Gerard P.

One<br />of the consequences of this popularisation of forensic science was a<br />sharp change in the attitude of investigators, who increasingly tend<br />to delegate to scientists the collection of information necessary to<br />identify the perpetrator of the crime. However, the prominent focus<br />on the search of biological traces or fingerprints, due to their high<br />potential for the personal identification of the individuals present at<br />the crime scene, somewhat fade the interest towards other kinds of<br />evidence, such as trace evidence. This kind of evidence is in fact<br />perceived by judges and lawyers as less informative, because they<br />think that “all plastic items are the same”, i.e. that it is impossible to<br />discriminate among mass produced items. The purpose of this paper<br />is to stress that, with sound methods for interpreting evidence, it<br />is possible to improve the communication between the scientist and<br />the Court, and to show the real significance of the analytical results,<br />in the context of the case.<br />The analysis of the traces found on a knife used in a murder<br />case were performed by optical microscopy, IR spectroscopy, and<br />UV-visible spectroscopy. The interpretation of evidence was carried<br />out according to a Bayesian approach.<br />A description of the interpretation of evidence in a case in<br />which fibres were the key evidence. It is shown that the key aspects<br />for having a high value of the evidence are the circumstances of the<br />case and the reconstruction of the events given by the prosecutor<br />and by the defence, in addition of course to a sound analytical procedure.<br />In other words, it is shown that in some cases the evidential<br />value of fibres or other trace evidence can be very high, sometimes<br />comparable to that of fingerprints or DNA: when properly interpreted,<br />trace evidence can give key information for solving cases.</p> Marta Da Pian Pietro Carresi Valerio Causin Copyright (c) 2019 Arab Journal of Forensic Sciences & Forensic Medicine (AJFSFM) 2019-05-23 2019-05-23 2 1 1285 1285 10.26735/16586794.2019.016 Phase Transfer Catalysis in the Aid of Fingerprint Development <p>This paper relates to the application of a novel spray formulation<br />for developing latent fingermarks on a wide range of crime<br />scene evidences. The formulation is based on a xanthene dye, rose<br />Bengal, and a phase transfer catalyst, t-tetrabutylammonium iodide.<br />It takes just 2-3 minutes to develop optimum on a broad spectrum<br />of fingerprint evidences of non-porous, semi porous and porous<br />substrates. It also detects fingerprints on items that are white and<br />multi-colored, and smooth and rough.<br />In addition, it develops fingerprints on a variety of adhesive<br />tapes, including duct tape, which is used by suicide bombers to<br />wrap explosives on their bodies.<br />It also detects impressions on such items that have been exposed<br />to water and high temperatures. The spray solution is prepared<br />in water. The ingredients of the formulation are non-toxic,<br />cheap and easily procurable.</p> Gurvinder S.

There are various methods for postmortem<br />retrieval of sperm. Modern medicine has progressed to a<br />stage where posthumous gamete retrieval with subsequent reproduction<br />has become a possibility. However, very little has been<br />discussed regarding guidelines orethical, social, and medical issues<br />related to such a procedure. The procedure is a boon for families<br />who might have become saddened by the untimely death of their<br />son. The procedure can be useful for not only the spouse of married<br />individuals but also to their parents. Also, such a procedure can be<br />very helpful to the parents of their unmarried son, who was their<br />sole support. However, there is no discussion of using such PMSR<br />techniques in married as well as unmarried individuals if requested<br />by close relatives. The present paper discusses the issues regarding<br />PMSR in deceased individuals and the various issues that may<br />arise.</p> Nilesh K. Tumram Rajesh V.

This paper<br />presents a review of forensic investigations into improvised<br />explosive device (IED) cases in the Kingdom of Bahrain from<br />2011.<br />A total of four IED investigations were reviewed (i.e Directionally<br />focused charges (DFC), Directional Focused Fragmentation<br />Charge (DFFC) and Explosively formed penetrator/<br />projectiles (EFP). DNA recovery utilized different collection<br />methods, such as swabbing, tape lifting, wiping and direct<br />cutting of certain separated parts of the IEDs. Samples were<br />extracted and purified with magnetic beads chemistry and<br />quantified. Low copy DNA extracts were subjected to different<br />concentration steps, and DNA extracts were amplified and<br />processed for detection to obtain reliable results. Using the results<br />of the study, we have developed the concept of Forensic<br />DNA Intelligence, which involves the extraction of human cells<br />deposited in low copy number in challenging areas within the<br />evidence which can lead to significant results.<br />This article will be very useful and informative to assist the<br />forensic community in terrorism cases applications worldwide.<br />Continued efforts must be made to re-evaluate standard operating<br />protocols with empirical studies.</p> Noora R.

In spite<br />of the progress achieved in the field of toxicology and associated<br />therapies, AlP is still responsible for a high rate of mortality due to<br />the rapid onset of life-threatening symptoms, ineffective treatment<br />and inadequate data on the efficacy of therapeutic interventions.<br />AlP poisoning is a serious medical emergency demanding early and<br />adequate management.<br />In this prospective study of AlP toxicity, 44 patients admitted to<br />emergency unit of Assiut university hospital in the period from 1st<br />January to 30th June 2016 were included.<br />There were 28 males (68.2%) and 16 females (31.8%). The majority<br />of the cases were in the age group from 21 to 30 years (n=28,<br />54.6%). Thirty-six (81.8%) of admitted patients were from rural<br />areas. Suicidal intake was the main mode of toxicity in 81.8% of<br />cases. About 41% of the cases were shocked at their presentation<br />and had metabolic acidosis. The mortality rate was 45.5%. The incidence<br />of death in patients treated with N-acetyl cysteine to the<br />incidence of death in non-treated patients was 1:12.<br />AlP poisoning needs more attention due to associated fatality,<br />the absence of an antidote, and a high number of youth victims.<br />Supportive measures are vital in these patients.

The prosecution forensic expert had<br />submitted his evidence using complex medical and scientific language<br />that misled the jury. The defence expert failed to challenge<br />him. A few years later, Mrs. Clark was proven innocent, as there was<br />undisclosed evidence and the language of the prosecution forensic<br />expert misled the jury. This paper raises some issues according to<br />the Sally Clark case. It includes some discussions about the expert’s<br />role in the adversarial system and also compares it with the inquisitorial<br />system. It is an approach towards understanding whether the<br />expert should stand in the witness box or not. This paper answers<br />whether the decision in the Sally Clark would have taken a different<br />direction, if it was dealt under the inquisitorial justice system<br />or other experts’ systems. Although this case has helped to re-open<br />many other cases, it has not encouraged the English criminal justice<br />system to make any changes with the expert system (especially in<br />complex forensic cases). It also affected experts who now think that<br />testifying in court is a risk. This paper presents a new approach that,<br />if considered, can protect the justice system from any miscarriages,<br />the experts themselves from being blamed and the public who look<br />at both as killers.</p> Huda M.

High concentrations of metals may<br />lead to potential toxicity in cases of overconsumption over a long<br />period of time. Metal content in alcoholic beverages may be used<br />to ascertain their authenticity and geographic origin. Therefore, determination<br />of metals in alcoholic beverages becomes a matter of<br />utmost importance to forensic agencies.<br />Many analytical techniques are available for qualitative and<br />quantitative estimation of metals. Stripping methods can be used,<br />and anodic stripping voltammetry proves to be a cheap, sensitive,<br />reliable and less time-consuming method. With advancements in<br />the field of electrodes, the sensitivity of voltammetry has greatly<br />increased, making it an ideal analytical technique for the analysis<br />of metals in wines and other alcoholic beverages.<br />In the present review, an attempt has been made to critically<br />review the various aspects of voltammetry with particular attention<br />to stripping methods along with their application in determination<br />of metal content in various alcoholic beverages.</p> Praveen K.

It is used in suicides and,<br />hence, acquires forensic impact.<br />Sixty adult male albino mice weighing 30-40 g were subjected<br />to a sub-lethal dose of sodium arsenate (40 mg/kg body weight)<br />to investigate hematological, biochemical and histopathological alterations<br />in liver and kidney. The mice were also co-treated with<br />green tea, garlic and vitamin C to reveal the protective role of these<br />herbal and synthetic antioxidants.<br />Arsenic induced significant declines in all blood parameters,<br />while green tea, garlic and vitamin C ameliorated these affected<br />hematological parameters. Alanine transaminase (ALT) and aspartate<br />transaminase (AST) were significantly increased in the sodium<br />arsenate treated group, while green tea, garlic and vitamin C ameliorated<br />these increases in enzyme levels. Creatinine and urea were<br />significantly increased in arsenic treated mice. These renal parameters<br />become normal in mice co-treated with green tea, garlic and<br />vitamin C. Arsenate-treated mice showed venous congestion, sinusoidal<br />dilatation, mononuclear cell infiltration and periportal fibrosis<br />in liver sections. Kidney samples from the same group revealed<br />interstitial hemorrhages, mononuclear cell infiltration, glomerulonephritis<br />and proximal tubular necrosis. Hepato-renal injuries were<br />greatly reduced, particularly in animals that received both green tea<br />and garlic.<br />The herbs used have a potential for ameliorating and protecting<br />against the hepato-renal toxicity caused by arsenic and need further<br />studies.
