Investigation Process

The cluster-footprint left at a crime scene is one of the most common trace evidence in the field of criminal investigation. Through analyzing and calculating the plane footprint, the investigators can get some important feature information such as step size, age and height, etc. However, this way is difficult to apply to reality without any errors in the process of manual calculations. Information management is more complicated in the later, the efficiency is relatively low too. To solve above problems, a testing system is designed and developed to analyze cluster-footprint. This system is based on the LabVIEW platform, which can realize image acquisition, stride characteristics extraction, information management and so on. Actual analysis results show that this system can effectively achieve these functions, working accuracy and efficiency can meet requirements of criminal investigation process.

Human footprints and footwear traces were one of the first well-studied forensic objects of examination. This is due to the fact that these traces are most often found at the scene of the incident, as well as by the fact that they contain most valuable and significant information needed for criminal investigation. Forensic examination of footprints and footwear traces of a person are among the most common trace evidence examinations encountered in practice, and defining a human height based on footprints is relevant and important in terms of obtaining primary (up-to-date), and later evidentiary information for a successful investigation and crime detection. The approximate height of a person, as indicated in the current trace evidence literature, can be established by using a certain number of the most common methods, one of which is to establish height by the total length of the trace. However, the existing today methods for calculating human height by foot traces (footprints) have certain disadvantages, which are mentioned in this article. The article purpose is to analyze current known methods and techniques for determining human height by footwear (feet) traces, conducting practical research on a given topic, indicating objective defects and the presence of a number of errors that are not taken into account while calculations, formulation of a reasonable conclusion based on the analyzed results of an examination. In the course of the analysis of forensic practice, a number of problematic issues was identified that make it difficult to objectively determine a person’s height by footwear traces, namely: non-conformity between the real value of human height and the height value calculated according to the most common formulas given in the forensic literature; non-compliance with standards by manufacturers while the production of shoes; lack of catalogues on shoe production, information on trace formation and the environment when examining a crime scene. All the above factors have a significant impact on the establishment of real human height by foot traces (footprints), and the absence or variability of at least one of these indicators leads to significant differences in the final values. Our research has shown that each individual foot length corresponds to not one, but several height indicators at once. At the same time the limit intervals of the height range are not the same for all foot lengths (3-20 cm for men and 6-20 cm for women). The above-mentioned discrepancies in the data are unacceptable while criminal investigation for the persons involved in crimes commission. The methods of establishing a person’s height described in the forensic literature are imperfect and require modification or revision. The conducted analysis indicates the necessity for further research on correlation dependence of the foot length and a person height taking into account all variables of indicators which have been listed above, since the efficiency of the way for establishing a person height by foot and footwear traces will depend on the right adjustment of the given parameter.

It is still found that investigating officers do not have an S1 degree or equivalent in thejurisdiction of the Sambass Resort Police as mandated in PP No. 58 of 2010 concerningAmendments to Government Regulation Number 27 of 1983 concerning theImplementation of KUHAP article 2A paragraph (1) letter a. If the requirements ofinvestigators are not fulfilled, there will automatically be limits of authority, includingthe inability to issue investigation orders, detention warrants and other administrativeletters. This study used a qualitative method with juridical empirical research. Toobtain accurate data, purposive sampling technique was used, and primary datacollection by conducting in-depth interviews. The research results found, among others:first, discretion regarding the administration of investigations in the jurisdiction of theSambas Resort Police for the Sambas District Police who do not have investigatingofficers who meet the requirements, is then taken over by the Head of the CriminalInvestigation Unit as the supervisor of the integrated criminal investigation function.Second, the impact of an integrated investigation administration causes the time tocarry out investigations to be slow due to the long distance between the Sector Policeand the Resort Police.

The article is an excerpt from the biography of the Russian writer, historian and collector of curiosities F. Dmitriev-Mamonov, to be published by B.S.G.-Press. The fragment considers three hitherto undisclosed episodes of his life: the 1770 criminal investigation of Mamonov’s attempted poisoning by the writer and former lecturer of the Land Gentry Cadet Corps Johann Fonberg, who had worked as his personal librarian for two months; followed by problems with his mental health in the 1780s, when he began suspecting that his closest family were plotting to kill him and began to subject his serfs to harsh punishments; and, finally, his donations to Moscow University in May 1770, in February 1772 and, probably, in November 1779, which consisted of a collection of medals, copies of P. Lippert’s engraved gems, and the portrait of field marshal P. Saltykov. All three instances appear connected: the donations coincide with three major incidents in Mamonov’s life (the attempted poisoning, a bad wound sustained in Chudov monastery during the suppression of the Plague revolt, and official proceedings against him for cruel treatment of serfs), which forced him to contemplate his mortality and the need to plan for the future of his collection.

AbstractForensic evidence is an evolving science in the field of criminal investigation and prosecutions. It has been widely used in the administration of justice in the courts and the Western legal system, particularly in common law.

The relevance of the study of individual psychological characteristics of employees of criminal investigation departments in transport in the North-Western Federal district of the Ministry of Internal Affairs of Russia (hereinafter referred to as the NWFD) in relation to indicators of professional deformation is due to the specific features of their official activities. Despite a significant amount of research on the phenomenon of professional deformity of police officers, there are few thoroughly developed and completed works on the prevention of professional deformities of police officers. The purpose of our research was to study the individual psychological characteristics of employees of criminal investigation departments in connection with the risk of professional deformation. The results of the empirical study were processed by correlation and factor analysis (49 parameters). The results of the initial analysis showed that the overall assessment of job satisfaction among employees of the studied departments is average with a downward trend. The results of the study on «professional burnout» revealed that a number of employees surveyed are close to emotional exhaustion. It is established that empathic abilities, social intelligence, and constructive coping strategies play an important role in the structure of individual psychological characteristics of police officers. Low ability of employees to learn behavior determines non-constructive strategies and models for coping with stressful situations, which leads to deformation of relationships with other people, i.e. to professional deformation. The obtained data can be used as the basis for the program of psychoprophylaxis of professional deformation of criminal investigation units in transport in the northwestern Federal district.
