Visualizing Digital Forensic Datasets: A Proof of Concept

Digital forensic visualization is an understudied area despite its potential to achieve significant improvements in the efficiency of an investigation, criminal or civil. In this study, a three‐stage forensic data storage and visualization life cycle is presented. The first stage is the decoding of data, which involves preparing both structured and unstructured data for storage. In the storage stage, data are stored within our proposed database schema designed for ensuring data integrity and speed of storage and retrieval. The final stage is the visualization of stored data in a manner that facilitates user interaction. These functionalities are implemented in a proof of concept to demonstrate the utility of the proposed life cycle. The proof of concept demonstrates the utility of the proposed approach for the storage and visualization of digital forensic data.     

Independence day explosion on lovers key

The display of fireworks is a popular holiday celebration in the United States. Because injuries due to recreational fireworks-related explosions among private consumers are relatively common, the sale of fireworks is regulated by the federal government and is also limited by state and local laws. In contrast, because fireworks display companies are under tight safety regulations, explosions in the professional pyrotechnics industry are uncommon occurrences, and the literature contains rare reports of injuries and fatalities resulting from such explosions. We report the 2003 Fourth of July commercial fireworks explosion on Lovers Key in southwest Florida that resulted in five fatalities. Events occurring during the investigation of the scene of this explosion illustrate the unique considerations and hazards for medicolegal death investigators, law enforcement and other investigative agencies. Additionally, this case demonstrates unusual aspects of the postmortem examinations performed on victims of fireworks-related incidents.

An initial evaluation of stable isotopic characterisation of post-blast plastic debris from improvised explosive devices

A number of two-way radios, similar to those which have been employed to initiate Improvised Explosive Devices (IEDs), were acquired from a commercial supplier and grouped into four pairs. Samples of plastic material were collected from five distinct regions of each radio and analysed by Infrared and Raman spectroscopy to identify the nature of the material. One radio of each pair was then subjected to detonation with a commercially available plastic explosive. The combination of radio and explosive was considered to be representative of the components of an IED. Following detonation, fragments were recovered and, where possible, identified as specific sampling points of the radio.A combination of δ²H and δ¹³C stable isotopic analysis of material from each of the five sampling points was found to provide a pattern which was characteristic of a given radio and provided a means to associate pairs of radios. When few fragments were recovered, no positive association could be made between the fragments and the paired, undamaged radio. This was attributed, in part, to manufacturing variation in the radios. However, when three or more post-blast fragments were recovered it was possible to associate these with the paired, undamaged radio with a high degree of certainty.     

恐怖爆炸仍为世界和平的主要威胁

当前,在恐怖活动当中。恐怖爆炸袭击占主导地位,并呈现不断恶化的趋势,袭击方式主要是自杀式恐怖爆炸,袭击目标转向平民和民用设施,伤亡人数逐年递增。且多为平民和警察。恐怖活动不断向中东、南亚等少数地区集中。恐怖爆炸威胁着世界和平。     

Increased Hematocrit Due to Electrical‐Waveform Exposures in Splenectomized Sus scrofa,

In laboratory studies of the pig Sus scrofa, hematocrit has consistently increased after conducted‐electrical‐weapon (CEW) exposures, possibly due to contraction of the spleen. Splenectomized animals and intact sham control animals were exposed, each for 30 sec, to a benchtop‐produced electrical waveform of net charge levels similar to those of some CEWs. Changes in the blood were compared statistically. Hematocrit increased significantly in both splenectomized and sham animals. There were no significant main‐effect differences between values of hematocrit from the two groups. There were, however, significant interactive effects of time and splenectomy for hematocrit, red blood cell count, and hemoglobin. After peak values were reached for these variables, values returned toward baseline levels more slowly in splenectomized animals. This may have been due to the lack of a spleen to sequester red blood cells (thereby resulting in more cells remaining in the general circulation), unlike sham animals with intact spleens.     

Loose‐Lipped Mobile Device Intelligent Personal Assistants: A Discussion of Information Gleaned from Siri on Locked iOS Devices

The forensic analysis of mobile handsets is becoming a more prominent factor in many criminal investigations. Despite such devices frequently storing relevant evidential content to support an investigation, accessing this information is becoming an increasingly difficult task due to enhanced effective security features. Where access to a device's resident data is not possible via traditional mobile forensic methods, in some cases it may still be possible to extract user information via queries made to an installed intelligent personal assistant. This article presents an evaluation of the information which is retrievable from Apple's Siri when interacted with on a locked iOS device running iOS 11.2.5 (the latest at the time of testing). The testing of verbal commands designed to elicit a response from Siri demonstrate the ability to recover call log, SMS, Contacts, Apple Maps, Calendar, and device information which may support any further investigation.     

爆炸案件中故意伤害罪和故意杀人罪界定探析

在爆炸案件审理的司法实践中,故意伤害罪和故意杀人罪的界定存在一定难度。司法机关工作人员不仅应该以犯罪行为人的主观故意为主要依据,还必须考虑爆炸手段、爆炸结果等客观方面的内容。     

The Italian Mediation Explosion: Lessons in Realpolitik

Between the time that the first modern Italian mediation statutes were issued in 1993 and March 2011, when mandatory mediation procedures under Italian Legislative Decree 28/2010 went into effect, an interesting paradox emerged in Italian mediation: mediation usage was virtually nonexistent despite the high success rates of mediated cases. Clearly, the mere availability of mediation was not sufficient to attract disputants away from the courts, even though the Italian court backlog skyrocketed to 5.4 million cases during this period. Decree 28/2010 was issued by the Italian government to address this paradox through a mandatory mediation requirement, but the law has faced significant opposition from some members of the Italian bar in the form of public strikes and legal challenges. Legislators have responded to this dissent with reactionary amendments to “cure” problems in the regulatory structure, even though there has also been significant positive attention paid to the Italian mediation model at the European level. As the opposition to Decree 28/2010 now appears to be diminishing and recent data indicate that mandatory mediation is achieving its objectives (to the tune of tens of thousands of mediated cases since March 2011), two lessons in realpolitik emerge for mediation proponents. First, nothing less than compulsion can rapidly increase mediation use. Second, the legislator who compels mediation without openly engaging the opposition is not mediation savvy, for even in compelling a policy choice, one should be respectful and mindful of the opponent's position, if for no other reason than to minimize his or her opposition to the final result.
