Genetic Identification of Burnt Bodies Based on Biological Remains Preserved at Scenes of Acts of Terrorism, Disasters, and Criminal Acts

Internal Security

2009

tom 1(1)

85-94

Contemporary reality poses great challenges to forensic medicine. Despite relevant tactics, techniques, and strategies having been developed, we are often helpless when surprised by terrorist assaults, disasters and different kinds of crime.It is essential to establish an overall procedure to be followed in case of calamities affecting the mankind, most frequently accompanied by fire and operation of high temperatures on human tissues. Hence, the goal is to (i) enrich forensic practice by a consistent procedural algorithm while discovering and securing traces, and categorising biological material as part of examining scenes of mass destruction, and to (ii) implement adequate molecular analyses in identifying individuals.The work has two objectives: to launch procedures for terrorist assaults, disasters and/or criminal acts, and to verify a number of methods that permit to identify strongly thermally degraded DNA. Such a material is often available in forensic medicine and court genetics, not only as a result of decaying processes, causing large reduction of the actual amount of DNA array, but also as a result of high temperature operation on human tissues. It should be stressed that all activities have to be properly conducted to prevent contamination. The genetic identification involved many different human tissues, i.e. hair, skeletal femoral muscles, teeth, internal organs, fragments of skin and long bones, combusted in a laboratory oven for different durations and temperatures: 100–1100 oC.

Suicide Death and the Action of Psychoactive Substances on the Body

This report deals with the possible causes of suicidal death, which is often caused by psychoactive substances. It is not about the impact that damages individual human organs, but about the action that causes changes in an individual’s psyche. Drugs that are taken for various reasons for a long time can cause dependence on them, and sometimes they also lead to the appearance of suicidal thoughts. The author, concerned about the situation of the increasing number of suicides in our country within the last two years, decided to write an article. Mainly, it is targeted at people who often do not realize the possibility of addiction to drugs, the so-called afterburners, alcohol or other psychological means of self-destruction. The case described in the article is aimed at making people aware that addictions take place in different environments, and that individuals with well-being can take their own lives for reasons only known to them. In order to prevent, or at least significantly reduce the number of cases associated with the intake of psychoactive substances, which may also contribute to taking one’s own life, preventive measures are necessary. One should make adults (mainly parents) aware of their unconscious impact on the emergence of addictions to toxic agents on both the physical and mental health of emotionally immature juveniles. The young generation may not see alternatives to a distant future, and it is the duty of those who are responsible for them to show them the sense in continuing their existence.

Unmanned Aerial Vehicles ‘in service’ of Internal Security of the State

The study was created thanks to the author’s preferences to learn increasingly more about new technologies that are able to increase the potential of internal security of the state. Recently, interest in recording areas (difficult to access, dangerous, monitored in adverse weather conditions, monitored due to the implementation of tasks by relevant services), the development of methods enabling the transmission of various materials at a distance, and performing other complicated activities have increased. For this purpose, unmanned aerial vehicles (so-called drones, UAVs) that are versatile in many respects are used. The author noticed the need to disseminate such innovative devices on native soil, especially for using them in multidirectional strengthening of the security sphere. Polish companies producing UAVs for many foreign customers have already marked their presence in this matter. The achievements of the designers are so impressive that it makes us appreciate the development of our technical thought, and above all, the use of drones to ensure security and public order in Poland. A series of training courses is already conducted by the Police Academy in Szczytno, which is a good solution both for teachers and, above all, for the trainees themselves. Such an initiative will undoubtedly translate into increased interest in drones, and especially the incredible usefulness of these devices for uniformed services and other entities.
