It is usually not possible to detect alkaloids and other organic or volatile poisons in burnt bones and ashes; and it is often contended on behalf of the accused that -it is impossible to detect arsenic in burnt bones and as...

I consider a model for the control of criminality in cities. The model was developed during my REU at UCLA. The model is a system of partial differential equations that simulates the behavior of criminals and where theymay accumulate, hot spots. I have proved a prior bounds for the partial differential equations inbothone-dimensional andhigherdimensional case, which proves the attractiveness an...

As more criminals use encryption to conceal incriminating evidence, forensic examiners require practical methods for recovering some or all of the encrypted data. This paper presents lessons learned from investigations involving encryption in various contexts. By presenting successful and unsuccessful case examples, this paper gives forensic examiners a clearer understanding of the feasibility ...

One of the recently addressed research directions focuses on the issues raised by the diffusion of highly dynamic on-line information, particularly on the problem of mining topic evolutions from news. Among several applications, risk identification and analysis may exploit mining topic evolution from news in order to support law enforcement officers in risk and threat assessment. Assimilating t...

From the development of the psychiatric concept of psychopathy, we can at this juncture only state that it no longer coincides at all with that of the delinquent and that we nevertheless find psychopaths among all kinds of criminals. Latent criminals, analogous to the latent misfits of Aichhorn, are frequently psychopaths. Social maladjustment may be however, far from being psychopathic, even i...

Around the beginning of the 21st century, something changed. Criminals started to see business opportunities from compromising and remotely controlling machines. Since then, opportunistic, organized and profit-driven attacks have been rising at an extraordinary pace. For the last 10–15 years the cyber criminals' goal has been to infect as many targets as possible in order to create new botnets ...

Canada exhibits no correlation between income and victimization, rich neighborhoods are less exposed to property crime, households more victimized than their neighbors, invest in protection. We provide a theory consistent with these facts. Criminals within city choose neighborhood pay search cost compare potential victims, whereas self-protection. As criminals' return increases income, likelier...
