The Recovery of Latent Fingermarks from Evidence Exposed to Ionizing Radiation*

Abstract: Continual reports of illicit trafficking incidents involving radioactive materials have prompted authorities to consider the likelihood of forensic evidence being exposed to radiation. In this study, we investigated the ability to recover latent fingermark evidence from a variety of substrates that were exposed to ionizing radiation. Fingermarks deposited on common surfaces, including aluminum, glass, office paper, and plastic, were exposed to doses ranging from 1 to 1000 kGy, in an effort to simulate realistic situations where evidence is exposed to significant doses of radiation from sources used in a criminal act. The fingermarks were processed using routine fingermark detection techniques. With the exception of glass and aluminum substrates, radiolysis had a considerable effect on the quality of the developed fingermarks. The damage to ridge characteristics can, in part, be attributed to chemical interactions between the substrate and the components of the fingermark secretions that react with the detection reagents.

Dissolution and Reintegration in Finland, 1914–1932: How did a Disarmed Country Become Absorbed into Brutalization?

Finland avoided participation in the Great War, but in 1918 fell into a short civil war that culminated in a cycle of vicious terror. The focus of this article is to explain the high incidence of terror during that civil war in comparison with other civil wars that took place in the Baltic region. The violent polarization of Finnish society was triggered as reform expectations skyrocketed at the moment when the country’s institutions were in chaos and its economy in a free fall. Mutual distrust, armed mobilizations, and a sense that time was running out in the arms race were key factors that drove both warring parties to the violent conflict. The author concludes with a discussion of the reintegration of the dissolved state. He frames the conflict within various psychological theories and group behavior in the context of economic possibilities and expectations. The article is based on his own empirical research and on the studies of other scholars on the history of the Finnish Civil War.     

Ingredients of a Successful Track Two Negotiation

During three days in 2003, an Israeli–Palestinian group met in London to negotiate the draft of the “Geneva Initiative,” which offered a potential final status agreement between Israel and Palestine. In this article, I analyze the video recording of these unofficial negotiations and examine how the framing and conduct of the talks enabled significant progress toward reaching an agreement. I describe six main framing techniques used by the mediators: calling the meetings an “exercise,” which reduced restraints on the participants and enhanced their flexibility, avoiding deep historical issues to focus solely on future‐oriented pragmatic solutions, allowing the participants to discuss any topic they chose while deliberately avoiding crucial narrative issues, convincing the participants that this track two negotiation was crucial for the future of official Israeli–Palestinian relations, accentuating the parties' understandings and agreements with each other, and building a sense of superordinate group identity among the participants, to encourage cooperation. These components were the key “ingredients” for the first — and still the only — (unofficial) detailed proposal for an Israeli–Palestinian peace agreement. They provide lessons that could improve the success of other track two negotiations.     

Detection of Acetaminophen–Protein Adducts in Decedents with Suspected Opioid–Acetaminophen Combination Product Overdose

Acetaminophen overdose is a leading cause of drug‐induced liver failure in the United States. Acetaminophen–protein adducts have been suggested as a biomarker of hepatotoxicity. The purpose of this study was to determine whether protein‐derived acetaminophen–protein adducts are quantifiable in postmortem samples. Heart blood, femoral blood, and liver tissue were collected at autopsy from 22 decedents suspected of opioid–acetaminophen overdose. Samples were assayed for protein‐derived acetaminophen–protein adducts, acetaminophen, and selected opioids found in combination products containing acetaminophen. Protein‐derived APAP‐CYS was detected in 17 of 22 decedents and was measurable in blood that was not degraded or hemolyzed. Heart blood concentrations ranged from 11 ng/mL (0.1 μM) to 7817 ng/mL (28.9 μM). Protein‐derived acetaminophen–protein adducts were detectable in liver tissue for 20 of 22 decedents. Liver histology was also performed for all decedents, and no evidence of centrilobular hepatic necrosis was observed.     

Police interrogation practice in Slovenia

Interrogation techniques are well explored, but in Slovenia it has remained unknown what interrogation techniques are used and what the basic characteristics of suspect interrogations are. The Slovenian interrogation manual proposes some coercive interrogation techniques and neglects their weaknesses. The aim of the current study was to examine Slovenian police officers’ beliefs as to the basic characteristics of their interrogations and whether techniques proposed by the manual are used in practice to begin to provide some insight into what actually happens in such interrogations. A survey instrument was used to obtain self-report data from a sample of criminal investigators. From 86 completed questionnaires it was found that a typical interrogation of a suspect lasts around 90 minutes and is not recorded. Interviewers typically use three interrogation techniques namely (i) conducting interrogations in isolation; (ii) identifying contradictions in the suspect's story; and (iii) confronting the suspect with evidence. Findings suggest that some coercive interrogation techniques are used in practice (e.g. offering moral justifications, alluding to have evidence of guilt, good cop/bad cop routine, and minimization). The study is the first insight into the practices of Slovenian investigators when questioning suspects. Differences among general, white-collar and organized crime investigators are also discussed.
