Feil, Ed.D. Getting Hot Assistant Editor Tammy Feil, Ed.D. As you can probably tell from the cover of this issue we’ve decided to focus on arson this time. Fires cause hundreds of millions of dollars in damages and take the Book Editor Enrico Pelazzo lives of over a million people every year. And many of those fires are deliberately set. Firemen are concerned with putting out the fire (as they should be), but not Science Editor about preserving evidence. Fortunately, dedicated fire investigators know how to T. Ann Kosloski find clues among the ashes and get to the bottom of the issue. The field used to be full of misconceptions, and innocent people went to prison because of faulty Copy Editor Tammy Feil reasoning, but our interview with John Lentini clears up what and why changes have come to forensic fire investigation. But there’s more. Contributing Editor We’re also happy to offer labs on glass density and bloody footprints, as well as Jeanette Hencken a primer on making a druggist fold.

Walker winced. “The members of the Leopard gang,” the inspector continued, “are Al Foster, Bruce Diskin, Charlie Jensen, Damon O’Keefe, and Eddie Lyons. Their gang is pretty new, so we don’t know yet which one is the leader. Nor do we know which one is the killer. So far, all I’ve been able to dig up are these facts: “1.

REV. 483 (2019) EVIDENCE ON FIRE* VALENA E. BEETY & JENNIFER D. OLIVA** Fire science, a field largely developed by lay “arson investigators,” police officers, or similar first responders untrained in chemistry and physics, has been historically dominated by unreliable methodology, demonstrably false conclusions, and concomitant miscarriages of justice. Fire investigators are neither subject to proficiency testing nor required to obtain more than a high school education. Perhaps surprisingly, courts have largely spared many of the now- debunked tenets of fire investigation any serious scientific scrutiny in criminal arson cases. This Article contrasts the courts’ ongoing lax admissibility of unreliable fire-science evidence in criminal cases with their strict exclusion of the same flimsy evidence in civil cases, notwithstanding that both criminal and civil courts are required to operate under the same exclusionary rules for expert evidence. Judges are capable of ensuring that the forensic science evidence they admit at trial is reliable in both criminal and civil proceedings.

Gorbett, MScFPE, CFEI, IAAI-CFI, CFII, CFPS Eastern Kentucky University, USA and Wayne Chapdelaine, CFEI, IAAI-CFI, CFII Metro-Rural Fire Forensics ABSTRACT The fire investigation industry is considered to be lagging behind the rest of the forensic science fields in its assessment of the performance of methodological approaches and conclusions drawn by practitioners within the field. Despite the best efforts of certifying bodies and industry members, there are still many unknowns within the profession. This paper will present practical uses of the scientific method as it relates to Origin Determination. Several recommended practices have been identified and formatted to reflect the scientific method as utilized in NFPA 921. In addition, where practical, a gap analysis has been conducted on these processes with recommendations provided. INTRODUCTION Both NFPA 921 Guide for Fire and Explosion Investigations and NFPA 1033 Standard for Professional Qualifications for Fire Investigator clearly identify the scientific method (SM) as the methodology for investigating fire and explosion incidents. In a recent survey of approximately 600 professional fire investigators, it was shown that 74% and 77% of participants believe that NFPA 921 and 1033, respectively, are considered as authoritative for the fire investigation profession.1 Most fire investigators identify that they are aware that the scientific method is to be used when analyzing fire and explosion incidents.1 However, a quick review of work product, case studies, and sworn testimony illustrates that many fire investigators may state that they use the scientific method when in fact they do not.2 The work product should reflect the SM used for each of the processes.

The Application of Photography in Tackling Emerging Crime, A thesis submitted for Associateship of The Royal Photographic Society, pagination. © 2017 Paul Michael Gilmour ALL RIGHTS RESERVED To dad, in loving memory, Squibbs xx ABSTRACT The cost of crime to the world economy is significant. As crime has evolved it has become more organised and increasingly cyber enabled and is committed across borders of law enforcement jurisdictions. Furthermore, the social, political, financial and technological demands facing crime investigators are increasing. However, little attention has been given to the ways in which photography can help tackle emerging crime. This study examines the current literature to enable a thorough understanding and evaluation of current theory and context. The study focuses on key advancements in imaging science and discusses the benefits of photography in a wider range of crime investigations. It acknowledges the challenges that the criminal justice system has to deal with and examines them with references to case studies. Overall, this study makes a significant contribution to the understanding and application of forensic photography. Photography plays a key role but must embrace continual change to ensure that it remains relevant to modern policing.
