Criminal Dismemberment is the first book to examine dismemberment as a phenomenon in the context of criminal acts. While the number of such dismemberment cases in any given country is often small, the notion of dismemberment captures the imagination, often leading many to question the motivations as to why anyone would perpetrate such an unnatural act. The act of dismemberment, in its original form, referred to cutting, tearing, pulling, wrenching or otherwise separating the limbs from a living being as a form a capital punishment. In today’s society, it has become associated most frequently with the criminal act of sectioning the remains of the dead in an attempt to conceal the death and dispose of the remains or make the process of identification of the deceased more difficult to achieve. Drawing on expertise from leading forensic anthropologists, pathologists, and forensic materials engineers, the book brings together much of the literature on criminal dismemberment—viewing it from the investigative, forensic, and social science perspectives. Key features include: Psychological analysis of the perpetrator Detailed examination of case studies, anonymized from recent investigations Difficulties encountered in a dismemberment investigation Tool mark analysis, including knives and saws, accompanied by over 120 detailed, full-color illustrations and photographs Serves as a unique and useful resource in the investigation of dismembered human remains The diverse backgrounds of the contributors offers a thorough account of such topics as the history of dismemberment, the forensic pathology in such cases, the importance of developing a common vocabulary in terminology used, the legal admissibility in dismemberment cases. As such, Criminal Dismemberment will serve as a comprehensive reference for students and practitioners alike.

In forensics, fingerprints can be used to uniquely identify suspects in a crime. Similarly, a tool mark left at a crime scene can be used to identify the tool that was used. However, the current practice of identifying matching tool marks involves visual inspection of marks by forensic experts which can be a very subjective process. As a result, declared matches are often successfully challenged in court, so law enforcement agencies are particularly interested in encouraging research in more objective approaches. Our analysis is based on comparisons of profilometry data, essentially depth contours of a tool mark surface taken along a linear path. In current practice, for stronger support of a match or non-match, multiple marks are made in the lab under the same conditions by the suspect tool. We propose the use of a likelihood ratio test to analyze the difference between a sample of comparisons of lab tool marks to a field tool mark, against a sample of comparisons of two lab tool marks. Chumbley and others (2010) point out that the angle of incidence between the tool and the marked surface can have a substantial impact on the tool mark and on the effectiveness of both manual and algorithmic matching procedures. To better address this problem, we describe how the analysis can be enhanced to model the effect of tool angle and allow for angle estimation for a tool mark left at a crime scene. With sufficient development, such methods may lead to more defensible forensic analyses.

Forensic Firearm Examination provides the reader with a thorough understanding of theory, application, and process of firearm comparison. It is essential in the field of forensic firearm examination to not only understand the marks that examiners are observing, but more importantly learn where these marks come from during the manufacturing process. This book explores the various machining techniques utilized in the manufacturing process and the resulting marks left by those tools. This information will equip the examiner with the knowledge to answer questions posed by the legal system regarding the uniqueness or potential similarity of marks on firearms imparted to fired bullets and cartridge cases. Intended primarily for firearm and tool mark examiners, this valuable resource serves as a primary requirement for the training of firearm and tool mark examiners. Other forensic science disciplines who rely on pattern matching as a primary determining factor whether or not two objects may share a common source would also find utility in this work. Finally, it will be a valuable resource for attorneys who are seeking to understand better the scientific aspects of firearm identification. Written by a foremost expert in the field, Forensic Firearm Examination explores specific firearm manufacturing techniques and the resulting marks, which has not been covered in any book publication. Chris Monturo has over 23 years of experience as forensic firearm and tool mark examiner. Additionally, he is a distinguished member of the Association of Firearm and Tool Mark Examiners (AFTE), a past member of the Scientific Working Group for Firearm and Tool Marks (SWGGUN), past member of the Organization of Scientific Area Subcommittees (OSAC) for firearm and tool marks and has instructed courses in machining for the firearm examiner in the United States and Internationally.

In 2009, a National Academy of Sciences report called for investigation into the scienti c basis behind tool mark comparisons (National Academy of Sciences, 2009). Answering this call, Chumbley et al. (2010) attempted to prove or disprove the hypothesis that tool marks are unique to a single tool. They developed a statistical algorithm that could, in most cases, discern matching and non-matching tool marks made at di erent angles by sequentially numbered screwdriver tips. Moreover, in the cases where the algorithm misinterpreted a pair of marks, an experienced forensics examiner could discern the correct outcome. While this research served to con rm the basic assumptions behind tool mark analysis, it also suggested that statistical analysis software could help to reduce the examiner's workload. This led to a new tool mark analysis approach, introduced in this thesis, that relies on 3D scans of screwdriver tip and marked plate surfaces at the micrometer scale from an optical microscope. These scans are carefully cleaned to remove noise from the data acquisition process and assigned a coordinate system that mathematically de nes angles and twists in a natural way. The marking process is then simulated by using a 3D graphics software package to impart rotations to the tip and take the projection of the tip's geometry in the direction of tool travel. The edge of this projection, retrieved from the 3D graphics software, becomes a virtual tool mark. Using this method, virtual marks are made at increments of 5 and compared to a scan of the evidence mark. The previously developed statistical package from Chumbley et al. (2010) performs the comparison, comparing the similarity of the geometry of both marks to the similarity that would occur due to random chance. The resulting statistical measure of the likelihood of the match informs the examiner of the angle of the best matching virtual mark, allowing the examiner to focus his/her mark analysis on a smaller range of angles. Preliminary results are quite promising. In a study with both sides of 6 screwdriver tips and 34 corresponding marks, the method distinguished known matches from known non-matches with zero false positive matches and only two matches mistaken for non-matches. For matches, it could predict the correct marking angle within 5-10 . Moreover, on a standard desktop computer, the virtual marking software is capable of cleaning 3D tip and plate scans in minutes and producing a virtual mark and comparing it to a real mark in seconds. These results support several of the professional conclusions of the tool mark analysis com- munity, including the idea that marks produced by the same tool only match if they are made at similar angles. The method also displays the potential to automate part of the comparison process, freeing the examiner to focus on other tasks, which is important in busy, backlogged crime labs. Finally, the method o ers the unique chance to directly link an evidence mark to the tool that produced it while reducing potential damage to the evidence.

Humanity's most appalling crimes are solved by experts presenting painstakingly gathered evidence to the court of law. Investigators rely on physical, chemical and digital clues gathered at the scene of an incident to reconstruct beyond all reasonable doubt the events that occurred in order to bring criminals to justice. Enter the forensic team, tasked with providing objective recognition and identification and evaluating physical evidence (the clues) to support known or suspected circumstances. Far from the super-sleuths of fiction, the real-life masters of deduction occupy a world of dogged detection, analysing fingerprints or gait, identifying traces of toxins, drugs or explosives, matching digital data, performing anatomical dissection, disease diagnosis, facial reconstruction and environmental profiling.
