During a forensic investigation of a computer system, the ability to retrieve volatile information can be of critical importance. The contents of RAM could reveal malicious code running on the system that has been deleted from the hard drive or, better yet, that was never resident on the hard drive at all. RAM can also provide the programs most recently run and files most recently opened in the system. However, due to the nature of modern operating systems, these programs and files are not typically stored contiguously-which makes most retrieval efforts of files larger than one page size futile. To date, analysis of RAM images has been largely restricted to searching for ASCII string content, which typically only yields text information such as document fragments, passwords or scripts. This thesis explores the memory management structures in a SUSE Linux system (kernel version 2.6.13-15) to make sense out of the chaos in RAM and facilitate the retrieval of files/programs larger than one page size. The analysis includes methods for incorporating swap space information for files that may not reside completely within physical memory. The results of this thesis will become the basis of later research efforts in RAM forensics. This includes the creation of tools that will provide forensic analysts with a clear map of what is resident in the volatile memory of a system.

This study proposes the classification of the toolmark under the heads of zipper teeth as a subclass characteristic as outlined by the Association of Firearm and Toolmark Examiners (AFTE). Two separate cases in which zipper teeth were found at crime scenes prompted this study. Brass zipper teeth manufactured by YKK were taken from 20 pairs of jeans and studied using a Reichert comparison microscope at 4X power. Photographs were taken and over 750 comparisons made. It was found that the toolmarks on each side on the 20 zippers were unique and independent of all other sides. The observations made in this study indicate that classifying zipper teeth toolmarks as a subclass characteristic is valid.

1 Summary The presented thesis deals with methods of investigation of robberies. It comprises all essential parts of such methodology and therefore aims to provide a complex view on the subject. Moreover, the work offers a deeper insight into some particular methods of investigation and emphasizes psychological aspects of investigation as well as of crime prevention. Comparison with foreign author's view on the subject is also included. The work consists of ten chapters dedicated to separate components of investigation. Chapter one presents the subject of investigation - robbery, its place in Czech law and legal definition set out by the Criminal Code. Chapter two provides criminalistic description of a robbery from different points of view and includes a relatively large part concentrating on foreign literature and robbery categories presented therein. Chapter three lists typical evidence which can be found on the crime scene and points out psychological aspects of formation of witness's memories of the crime. Chapter four lists standard situations in which the investigator finds himself based on the amount and nature of information obtained. Chapter five looks at particular evidence needed in court in robbery cases. Chapters six and seven describe different ways in which crimes are reported and initial...

The methodology of investigation of crimes against life (selected problems) Abstract The topic of this thesis is the methodology of investigation of crimes against life. Due to the fact that this is undoubtedly a very wide topic and the investigation of all crimes against life follows the same principles using similar methods, this diploma thesis is focused on the method of a murder investigation as the most serious crime against life, if not the most serious criminal action of them all. The first chapter of my diploma thesis is devoted to the substantive regulation of all crimes against life according to § 140 to 144 of the Criminal Code.
