A new chemical aid for criminal investigation: dyes and latent prints
2002
Criminalistics is a field in which there are many opportunities for the practical application of chemical reagents and the use of analytical methods that provide answers to enigmas at crime scenes. Common reagents in biochemical and medical test methods can be useful for criminalistics (forensic science). Dyes are one type of reagent that can be used in obtaining crime scene evidence. This work describes a new application of CI Solvent Black 3 dye in the location of latent fingerprints. The results show that CI Solvent Black 3 can be successfully applied in the location and development of recent and non-recent latent fingerprints on porous surfaces.
‘There should be no open doors in the police’: criminal investigations in northern Ghana as boundary work
2012
ABSTRACTIn criminal investigations by police officers in northern Ghana, the lines are fluid: civilians arrest suspects on their own, assuming the tasks of the police. Police officers are heavily influenced by civilians, often forming paid alliances with them. Yet such entanglements paradoxically enable state policing and integrate the police into society in a context of low resources and low legitimacy. Other practices limit and frame such transgressions. Using the concept of boundary work, this article analyses how actors maintain and negotiate the seemingly blurred distinction between state and society in West Africa.
Interpretation of Diagnostic Imaging for Medicolegal Issues
2019
Forensic radiology is a relative recently emergent part of forensic medicine characterized by the application of radiological methods in criminal investigations, such as the forensic M.E’s radiological reports in civil or penal matters for judicial technical advice. The various imaging modalities like X-rays, Computed Tomography (CT), Magnetic Resonance Imaging (MRI), and ultrasonography can be used depending on various forms of cases and their requirements in routine investigations.
L'assistenza umanitaria delle ONG sotto inchiesta
2022
Lo scorso giugno, l’Agenzia dell’Unione europea per i diritti fondamentali (FRA) ha pubblicato il consueto aggiornamento semestrale sulle operazioni di Search and Rescue (SAR) nel Mediterraneo. Il documento evidenza le difficoltà di condurre le operazioni di salvataggio da parte delle imbarcazioni delle ONG, molte delle quali sono state (e continuano ad essere) sottoposte a procedimenti giudiziari e fermi amministrativi nelle giurisdizioni degli Stati membri dell’UE. Nel quadro del contrasto al traffico di migranti, infatti, è ormai impellente una riforma del Facilitator Package quantomeno nel senso di vietare agli Stati membri di criminalizzare l’attività di assistenza umanitaria delle ONG…
The Phenomenology of Specialization of Criminal Suspects
2012
A criminal career can be either general, with the criminal committing different types of crimes, or specialized, with the criminal committing a specific type of crime. A central problem in the study of crime specialization is to determine, from the perspective of the criminal, which crimes should be considered similar and which crimes should be considered distinct. We study a large set of Swedish suspects to empirically investigate generalist and specialist behavior in crime. We show that there is a large group of suspects who can be described as generalists. At the same time, we observe a non-trivial pattern of specialization across age and gender of suspects. Women are less prone to commi…
Criminal networks analysis in missing data scenarios through graph distances
2021
Data collected in criminal investigations may suffer from issues like: (i) incompleteness, due to the covert nature of criminal organizations; (ii) incorrectness, caused by either unintentional data collection errors or intentional deception by criminals; (iii) inconsistency, when the same information is collected into law enforcement databases multiple times, or in different formats. In this paper we analyze nine real criminal networks of different nature (i.e., Mafia networks, criminal street gangs and terrorist organizations) in order to quantify the impact of incomplete data, and to determine which network type is most affected by it. The networks are firstly pruned using two specific m…
Principios rectores en la adopción de diligencias limitativas de los derechos reconocidos en el art. 18 ce
2021
Criminal Procedure Law reform carried out in 2015 requires, in order to adopt the investigation proceedings that limit the rights recognized by art. 18 Spanish Constitution, to respect the guiding principles of specialty, suitability, exceptionality, necessity and proportionality. This article aims, departing from the legal text and considering existing jurisprudence, to unveil the true meaning of these principles.
