Modification Methods of Blank Pistols in Turkey in 2006

Abstract:  This study describes the modification methods of blank cartridge firing pistols in Turkey. We have examined cases submitted to the Aydın Regional Criminal Laboratory of Turkey in 2006. In total, 95 modified pistols and 300 modified cartridges were examined. The blank cartridge firing pistols are guns which look similar to real pistols, however, there are blockages in their barrel in order to prevent the discharge of a bullet. However, as a result of simple modifications, these pistols can be easily converted into real firearms. Studied modification methods are removing the obstruction from the barrel, removing the partial obstruction from the barrel, sleeving a smaller diameter tube into the original barrel, using a replacement barrel, and rifling the original barrel. Special cartridges for these modified pistols are also produced. These modified pistols and cartridges were evaluated in respect of the converting methods.     

Handmade Guns in Trabzon, Turkey

Abstract:  A wide variety of handmade firearms have been involved in criminal cases in the city of Trabzon, Turkey. Although they are often very similar to commercially manufactured firearms in terms of design, loading and locking mechanisms, and cocking and firing arrangements, these guns are constructed from cheap materials and are not safe for firing. Handmade firearms manufactured in the Black Sea region of Turkey, particularly in the city of Trabzon, are similar to pistols manufactured by Browning, Luger, Star, Smith and Wesson, Berretta, and MAB. A total of 201 handmade guns referred to the Criminal Police Laboratories for examination from 2003 to 2005 were evaluated with respect to type, number of barrels, size and caliber, rifling, design, mechanism, operability, legality, and similarity to commercial models. We found that most of these handmade guns resembled commercial models in several aspects.     

Foreigners Dying in Istanbul

Abstract:  The study included 411 deaths selected from 14,647 medicolegal deaths autopsied in the Morgue Department of Forensic Medicine Institute Directorate, affiliated with the Ministry of Justice, between 1998 and 2002. Data were collected from court documents, coroner's investigation reports, and autopsy reports. The parameters of age, gender, nationality and origin, cause and place of death in foreigners dying in Istanbul were evaluated in the study. Out of 14,647 medicolegal deaths, 3.5% were foreigners from 34 different nationalities. The nationality with the highest rate of foreigner deaths (34%) was Romanian. Out of 411 deaths, 74.3% were male and 25.7% were female. Of all cases, 64.4% were tourists visiting Istanbul and 35.6% had a job in Istanbul. Of 146 foreigners employed in Istanbul, 94.5% did not have a work permit, while only 5.5% had a work permit.     

The forensic deaths caused by pesticide poisoning between the years 2006 and 2009 in Izmir, Turkey

Pesticide poisoning is still a significant health problem in Turkey. We conducted a retrospective study of autopsy cases at Izmir Branch of the Council of Forensic Medicine to describe the characteristics of deaths caused by pesticide poisoning between 2006 and 2009. The distributions of the cases according to gender and age were as follows: men 74.1% (n = 40, mean [±SD] age, 44.7 ± 14.1), women 25.9% (n = 14, mean [±SD] age, 39.2 ± 18.9). The majority of pesticide-poisoning deaths were suicides (n = 43, 80%) followed by accidents (n = 4, 8%) and homicide (n = 1, 2%). The manner of death could not be determined in six cases (11%). Suicides mostly occurred at home (n = 26, 63%) (p < 0.05). Methomyl was the most frequent pesticide (n = 9, 17%) among the all cases. This study reported that most of the pesticides found in poisoning cases were highly hazardous types. Combined efforts of medical professionals and law makers are needed for enacting strict laws against highly hazardous pesticides.     

Heroin Overdose Deaths and Heroin Purity Between 1990 and 2000 in Istanbul,Turkey*

Abstract: Turkey has continuously experienced problems with abuse of, and addiction to, opium derivatives. In this study, we analyzed the relationship between heroin overdose deaths and the characteristics of seized opium derivatives. Data were gathered from the Council of Forensic Medicine of the Ministry of Justice in Istanbul from 1990 to 2000. There were 636 heroin‐related deaths during this period, 595 of which were classified as heroin overdose deaths. Mean crude and weighted heroin purities remained relatively constant and were calculated to be 46% (57–34%) and 51% (39–59%), respectively. The weight of heroin and the number of heroin seizures, but not the heroin purity, were significantly associated with the number of heroin‐related deaths. Prevention strategies are needed to reduce the number of deaths caused by overdoses in countries situated on drug trafficking routes. These strategies should focus on drug trafficking, by providing increased levels of, and support for, law enforcement, stopping the supply of precursor chemicals, and combating corruption among border officials.     

Computerized Image Analysis in Differentiation of Skin Lesions Caused by Electrocution, Flame Burns, and Abrasion

Abstract:  In the practice of forensic science, sometimes, it is not easy to understand whether skin lesion is due to electrocution and to differentiate the thermal burns and abrasion-type lesions, especially when electricity source cannot be revealed by death science investigation. Based on the causes of the lesions, cases were classified into three groups. Group 1 included 30 deaths from electrocution. Group 2 included 30 deaths with flame burns. Group 3 included 30 deaths from traffic accident cases, which had abrasions. In this study, epidermal nuclear area, perimeter, nuclear form factor, nuclear minimum axes, nuclear maximum axes, and minimum axes/maximum axes ratio were measured. As a result, we think that computerized image analysis beside light microscopic examination can be useful in the differentiation of the electrocution, flame burn, and abrasion type lesions.     

Patterns of Ecchymoses Caused by Manner of Death and Collateral Injuries Sustained in Bruising Incidents: Decedent Injuries,Profiles, Comparisons,and Clinicopathologic Significance

Abstract: We investigated how ecchymoses could be used to predict other injuries, or help establish the cause of death. Ecchymoses, fractures, lacerations, abrasions, and other data were recorded. Eleven percent of decedents had ecchymoses. Motor vehicle accident by car (MVA‐C) was the most common cause of ecchymoses and showed the most collateral injuries. Decedents of natural causes were more likely to have ecchymoses without collateral injuries. There appeared to be two groups of decedents with ecchymoses: one group is younger, comprised of victims of MVA‐C and homicides, with more injuries related to ecchymoses than others; another is an older group of victims of other accidents, natural causes, and suicide. There were no indeterminate causes of death among decedents with ecchymoses. Therefore, ecchymoses may be a surrogate marker to direct the pathologist to continue to seek a cause of death should be seen, even if the case, otherwise, appears to be indeterminate.     

Occurrence of contamination by controlled substances in Euro banknotes from the Spanish archipelago of the Canary Islands

The social problems of drug abuse are a matter of increasing global problem. Nowadays, international agencies need fresh methods to monitor trends of the use of illicit drugs. In this sense, small amounts of drugs are transferred to banknotes and they could be detected and quantified. An analytical procedure based upon extraction with organic solvent, liquid chromatography separation, and mass spectrometric detection allowed the identification of 21 drugs and metabolites in 120 used Euro banknotes collected in the Canary Islands (Spain). Most of the banknotes analyzed showed detectable drug residues (92.5%). Cocaine was the most frequently detected drug, present in approximately 90% of the samples. In addition, 75%, 35%, and 15% of the banknotes showed residues of amphetamine derivatives, opiates, and benzodiazepines, respectively. An average of three drug residues per banknote was detected. In summary, the presence of drug residues in banknotes could be useful as tracer for drugs prevalence.
