Crime Scene Analysis

Forensic DNA testing can play a critical role in homicide investigations. Selecting the appropriate evidence on which to perform DNA testing requires foresight and reasoning based on experience and science. Although successful DNA testing can occur using many substrates, including blood, hair, and sweat/epithelial cells, positive results can also result from testing various unorthodox samples. The authors report on a triple-murder investigation where DNA testing of dog feces at the crime scene matched DNA testing of feces found on the shoe of a suspect resulting in successful prosecution of the case.

Crime Scene Analysis

Crime scene investigation should be carried out using a critical forensic approach by an expert team. This provides essential tools in the research and collection of evidence and samples which must be integrated with the autopsy and the police officers’ investigations. This paper aims to highlight the importance of a multidisciplinary approach to crime scene investigation and describes a very interesting criminal case. As demonstrated by this case, the evidence obtained from the crime scene analysis sheds light on difficult cases, such as murders staged as suicides or accidents.

Crime Scene Analysis

Behavioural crime scene analysis (BCSA) is a police tool used to reconstruct an offence based on behaviours. Recently, BCSA has demonstrated clinical utility by predicting recidivism and aiding case conceptualization. However, a systematic review of BCSA models showed a paucity of research evaluating which behaviours are necessary and sufficient to model sexual offences. Groth and Birnbaum’s sex offender typology, which is based on offence behaviours, provides a theoretical framework that integrates investigative information and clinical practice. The purpose of this thesis was to evaluate statistical- and theory-based approaches to refine BCSA models that distinguish sexual offenders. In Studies 1 through 3, Multidimensional Scaling, Nonlinear Principal Component Analysis, and Latent Class Analysis were used to create statistically-driven and theory-driven behavioural models from 59 serial, stranger sexual offenders. Validity testing of the theory-driven model indicated that applying Groth and Birnbaum’s framework to BCSA could optimize both investigative efforts and clinical decision-making.
