Psychological Factors Underlying Criminal Behavior

In old fashioned history books, the highest tribute paid to a king was to say that he was just, he helped the poor and punished the wicked. In those days a law-abiding people were sorely in need of protection against powerful law-breakers. Today the power of the state is firmly established. True, quite a number of crimes are never detected; but no criminal has the slightest chance of openly defying society. If we read of a manhunt in the country we give the poor devil a fortnight at the outside; we know that by then the armed machinery of the law will surely have overtaken him. Society has the right and the duty to protect itself. But its superiority in strength over the individual delinquent

Non Familial Abductions

Abstract

When a person is abducted and the suspect is someone other than a family member, it is a difficult for police to decide where to look for the victim. To date, there has been little research conducted on how offenders select murder and disposal sites, and how far they travel to get to these areas. Past research pertains only to the United States and United Kingdom. Thus, investigators have little knowledge regarding relevant distance relationships in Canada, and how offenders chose the locations to dump victims. This thesis includes a review of previous research in this field, as well as a discussion of the strengths and weaknesses. As stranger homicides are infrequent crimes, all Canadian and Washington State cases were included. Using data from Violent Crimes Linkage Analysis system (ViCLAS) and Homicide Investigative Tracking System (HITS), this research examined victim and offender demographics, temporal and spatial factors, the disposal site, and the distances involved in the crime. The distances analyzed were between the offender and victim's residence, point of initial contact, murder scene and disposal site. Many distinctive patterns emerged, relating to the age of the victim and offender,...

Cold Case Models for Evaluating Unresolved Homicides

Abstract

During the period 1980-2008 the United States has accumulated nearly 185,000 unresolved murders. Based on the number of homicides and clearance rates for murders 2009-2012 this figure is either closer to, or well over 200,000. As of 2004 the United States also had approximately 14,000 unidentified sets of human remains, many of which could be homicides, further increasing our total number of unresolved cases.The efforts to resolve some of these cases by law enforcement and others have been unrelenting. And while historically we can easily identify the early 1980s with Dade County Sherriff’s Office as the beginnings of the “cold case concept” , a standard protocol for evaluating cold cases has not yet been identified and implemented, as noted by the Rand Corporation study for the National Institute of Justice (NIJ).4 The intent of this article is to provide the readers with two cold case models that can assist in streamlining the evaluation process and possibly significantly contribute to the resolution of cold cases.
