Visualization of Fingermarks Deposits on Untreated Thermal Paper Exploiting the Near Infrared Luminescence

Thermal paper is widely used as a print medium for different applications but it constitutes a tricky substrate for fingermark visualization. An earlier work (J Forensic Sci 2015; 60 :1034) reported how to visualize fingermarks on untreated thermal paper by illuminating the item with a UV-A light source. In the present paper, the potential of the near infrared (NIR) luminescence has been tested on thermal paper compared to the mentioned method. A controlled study was carried out utilizing eccrine enriched fingermarks. The promising outcomes obtained were further confirmed by performing a pseudo-operational trial. Data clearly showed that the use of the NIR filter gave better results. Finally, preliminary tests suggested a different mechanism of reaction induced by fingermarks with respect to the one behind the thermal printing. Thus, NIR luminescence represents a refinement to the suite of optical examination processes, including the potential to increase the number of marks recovered in a noncontact, nondestructive way.     

组织、领导传销活动罪与诈骗罪的竞合论探析--以利用保健食品传销犯罪为角度

利用保健食品传销犯罪是新型的传销犯罪,其在骗取财物的过程中涉及对保健食品的虚假宣传,其构成要件要素又与诈骗罪具有交叉部分,而"两高一部"的《关于办理组织领导传销活动刑事案件适用法律若干问题的意见》并未对组织、领导传销活动罪与诈骗罪之间的罪数讨论予以明示,有必要通过二罪理论上的竞合论争议,比较日本刑法的竞合论规定,结合我国竞合论的规定,明示利用保健食品传销犯罪与诈骗罪的交叉部分的罪名适用关系。     

The Special Needs of Victims of Torture or Serious Violence: A Qualitative Research in EU

Abstract

In recent years ongoing wars and serious violations of human rights have driven increasing numbers of people away from their homes, especially in the Middle East and Africa to countries in the European Union to seek asylum. It is estimated that between 5% and 35% of these asylum-seekers and refugees have suffered from torture or serious violence. Studies and practice have shown that an appropriate response to the special needs of victims of torture or serious violence contribute to reduce survivors’ suffering and provide properly international protection. EU legislation recognizes that such vulnerable individuals have special needs, but few of these needs have already been identified and recognized as such. This article reports on a qualitative study carried out in six EU countries - France, Germany, Greece, Italy, Malta and Portugal - to explore the special needs of victims of torture or serious violence who present among asylum-seekers, during the asylum request procedure, in reception, and throughout rehabilitation and social integration. The study aims to release into the academic community the results of a large policy and practice-oriented study.     

Electrocution by arcing: a nonfatal case study

Accidental electrocution during working activities account for a considerable amount of morbidity and mortality. Workers often misjudge the danger of electric wires or high-tension power cables, thereby exposing themselves to electrocution hazard. This article describes a nonfatal case of injuries by arcing from high-tension power-line cables involving a young farmer who was thrashing an olive tree by means of aluminum ladder. The circumstances surrounding the manner of electrocution and the features of electric injuries are presented and discussed.     

Occlusion of left and right coronary arteries and coronary sinus following blunt chest trauma

Blunt chest trauma from rapid automobile airbag deployment causing coronary artery occlusion and myocardial infarction is a rare but potentially fatal condition. We present the case of a 37-year-old man who developed extensive anterior and inferior myocardial infarction because of occlusion of both left anterior and right coronary arteries following blunt injury to the chest in a car accident. The patient was scheduled for emergency coronary angiography but left and right coronary ostia were not cannulated because of thrombus formation probably. The patient died, and the autopsy revealed external compression by epicardial hematomas involving separately left and right coronary arteries and the coronary sinus without signs of coronary and/or aortic dissection. To our knowledge, this is the first case presenting occlusion of both coronary arteries secondary to blunt chest trauma causing acute myocardial infarction in a young man without signs of prior coronary artery disease.     

Thermal development of latent fingermarks on porous surfaces—Further observations and refinements

In a further study of the thermal development of fingermarks on paper and similar surfaces, it is demonstrated that direct contact heating of the substrate using coated or ceramic surfaces at temperatures in excess of 230 °C produces results superior to those obtained using hot air. Fingermarks can also be developed in this way on other cellulose-based substrates such as wood and cotton fabric, though ridge detail is difficult to obtain in the latter case. Fluorescence spectroscopy indicates that the phenomena observed during the thermal development of fingermarks can be reproduced simply by heating untreated white copy paper or filter paper, or these papers treated with solutions of sodium chloride or alanine. There is no evidence to suggest that the observed fluorescence of fingermarks heated on paper is due to a reaction of fingermark constituents on or with the paper. Instead, we maintain that the ridge contrast observed first as fluorescence, and later as brown charring, is simply an acceleration of the thermal degradation of the paper. Thermal degradation of cellulose, a major constituent of paper and wood, is known to give rise to a fluorescent product if sufficient oxygen is available [1], [2], [3], [4], [5]. However, the absence of atmospheric oxygen has only a slight effect on the thermal development of fingermarks, indicating that there is sufficient oxygen already present in paper to allow the formation of the fluorescent and charred products. In a depletion study comparing thermal development of fingermarks on paper with development using ninhydrin, the thermal technique was found to be as sensitive as ninhydrin for six out of seven donors. When thermal development was used in sequence with ninhydrin and DFO, it was found that only fingermarks that had been developed to the fluorescent stage (a few seconds of heating) could subsequently be developed with the other reagents. In the reverse sequence, no useful further development was noted for fingermarks that were treated thermally after having been developed with ninhydrin or DFO. Aged fingermarks, including marks from 1-year-old university examination papers were successfully developed using the thermal technique.     

A study of distribution of ethyl glucuronide in different keratin matrices

Ethyl glucuronide (EtG) is a direct metabolite of ethanol, frequently used as a biomarker of alcohol abuse. To this purpose, EtG is preferentially determined in hair samples, using a cut-off value of 30pg/mg to discriminate between social and heavy drinkers, as recently fixed by an international consensus conference. Although this cut-off value is assumed for head hair, alternative matrices, such as pubic, axillary and chest hair, are often analyzed when head hair is not available. Previous studies suggested that determination of EtG in various keratin matrices may lead to different results; growth cycle and rate, urine contamination, distribution of sebum glands and other environmental factors are likely to contribute to these differences. We analyzed more than 2700 samples (head, pubic, chest and axillary hair) to evaluate the inter- and intra-individual distribution of the EtG concentration in the different keratin matrices. The data were interpreted on a statistical basis, on the assumption that large population data-sets will level off the average alcohol consumption of each group. From both inter- and intra-individual distribution data, significant differences were observed in EtG concentrations recorded in head, axillary and pubic hair samples. It is concluded that pubic hair cannot be utilized alternatively to head hair to prove chronic alcohol abuse, nor is axillary hair, since positive and negative biases respectively affect these determinations. In contrast, for chest hair, EtG distributions similar to head hair were found, although the large discrepancy between the examined population dimensions presently prevents any definitive conclusion. Thus, chest hair represents a promising alternative to head hair for EtG determinations, deserving further investigation on samples collected from the same individuals, in order to establish a clear correlation between their respective EtG concentrations.
