Development of a technologically advanced IT system enabling automated processing of information collected in forensic biometric databases in order to combat crime or identify people

Edyta Kot
Forensic biometric databases are an out of court tool to support the work of law enforcement agencies. They are used to detect the perpetrators of crimes, indicate the connections of a person with previously committed crimes, and allow the identification of living persons and corpses with unknown identity or individuals trying to hide their identity. In police practice, among the methods of identification of living persons and corpses, fingerprint and DNA tests are mainly used....

GLOSS to the decision of the Supreme Court of 28 March, 2017, III KK 472/16, lex/el.

Kazimierz J. Pawelec
The verdict of the Supreme Court was devoted to determining the land traffic criterion for the perpetrator of a road offence. The Supreme Court noted that the indicated concept should not be associated solely with the formal status of a given road, but with the criteria of its availability and actual use. This issue is extremely important for practice. Hence, the judgment comprises an analysis of the notion of land traffic from both juridical and...

Role of anthropological opinion in verification of eyewitness identification result

Piotr Herbowski & Dorota Lorkiewicz-Muszyńska
Probative value of results obtained in the course of legal proceedings with the participants of the criminal act may vary. This also concerns results of identification by an eyewitness. The exceptional role of its result in the criminal trial derives from the fact that categorical identification of a suspect by the witness becomes directly incriminating evidence. Problems connected with verification of identification parade result, which often occur both in Poland and in other countries, have...

Deliberate causing a catastrophe or its direct danger in road traffic. Controversy as regards the legal qualification of the crime

Kazimierz J. Pawelec
Causing a catastrophe in road traffic or the direct danger of its occurrence by deliberate misconduct has been a subject of disputes in both judicature and in science. In principle it was excluded that such a catastrophe or its immediate danger might be committed purposefully, with a direct intent, unless it involved a criminal offense, such as a terrorist attack that might consist in a multiple manslaughter, diversion or sabotage. On the other hand, committing...

Colour as a basic feature in comparative studies of fibre microtraces

Róża Starczak & Jolanta Wąs-Gubała
Forensic evidence in the form of fibres is recovered in cases involving sexual offenses, assault, murder and road accidents. In the event when a connection between persons is determined, fibres transferred from an offender’s to a victim’s clothing and vice versa are sought for. Colour is the first physico-chemical property verified during forensic analysis. Any colour differences between materials recovered at the crime scene and those originating from a suspect's clothing suggestthat fibres cannot have...

Problems encountered in the dactyloscopic investigation of anonymous corpses with fingerprint patterns preserved in silicone molds and the attempt to solve them

Paweł Malinowski
The article describes experiments conducted using the Automatic Fingerprint Identification System (AFIS), which demonstrated that replacing the standard search type TP/TP (card/card) with the type LT/TP (trace/ card) in conducting dactyloscopic investigations with fingerprint patterns preserved in silicone molds leads to optimal results. Moreover, a series of practical tips for investigators are included, covering the AFIS tools that should be used to obtain correct search results in the system and minimize the risk of errors.

Anthroposcopic classification of eye surroundings with eyes closed

Tomasz Przybyła
In the analyses for body identification based on visual recordings, differences in the analyzed material may be encountered. The evidence, as opposed to comparative material, usually contains images in which the eyes are closed. The aim of the study was to establish whether it is possible to perform the proper anthroposcopic classification of eye surroundings in such conditions. The study was conducted in a group of 98 subjects. It involved taking a series of photographs...

Cases of automatic firing with semiautomatic pistols

Henryk Juszczyk & Michał Borusiński
The article presents cases of endangering shooters and bystanders caused by wear of firearms parts or their incorrect assembling. The Authors analysed examples of disorders in P-83 and P-64 pistols. In P-83 pistol firing as if in an automatic mode became possible because of incorrect mounting of the firing pin in the slide while in P-64 pistol it resulted from wear of the firing pin and the safety block.

Sources of bias in examination of forensic traces

Mateusz Ignaszak
Every human being has a cognitive apparatus that he/she uses every day. Due to its limitations, we are susceptible to all kinds of cognitive errors that affect the observation of the world and decision making. Also forensic experts are not immune to external and internal factors that may cause issuing false opinions. The aim of the article is to show the multilevel problem of prevalence and susceptibility to any cognitive biases in the expertise of...

Wet Powder White – powder suspension applicable not only to the adhesive sides of adhesive tapes

Maciej Fabiszak
The article presents new possibilities of revealing fingerprints on non-absorbent surfaces by using Wet Powder White, known and used in Polish dactyloscopy. Powder suspension based on titanium dioxide has been successfully used to reveal fingerprints on the adhesive sides of non-porous tapes, as well as on the inner surfaces of rubber gloves. So far, however, the broader application of Wet Powder White has not been known in Polish dactyloscopic practice. Foreign publications quoted in the...

Vacuum metal deposition (VMD) – characteristics of the method

Tomasz Szczepański, Urszula Więckiewicz, Barbara Konior & Patryk Pucułek
Vacuum metal deposition was introduced in the process of visualization of latent fingermarks already in the 20th century. However, due to the requirement of using specialist equipment to ensure appropriate conditions for the development process, which would have generated significant costs, the method was not available in Poland. Technological developments, however, made it possible to create compact devices with smaller dimensions and lower parameters, which, nowadays, can be used in virtually every forensic fingerprint identification...
