Reconstructing with trace information: Does rapid identification information lead to better crime reconstructions?

Currently, promising new tools are under development that will enable crime scene investigators to analyze fingerprints or DNA‐traces at the crime scene. While these technologies could help to find a perpetrator early in the investigation, they may also strengthen confirmation bias when an incorrect scenario directs the investigation this early. In this study, 40 experienced Crime scene investigators (CSIs) investigated a mock crime scene to study the influence of rapid identification technologies on the investigation. This initial study shows that receiving identification information during the investigation results in more accurate scenarios. CSIs in general are not as much reconstructing the event that took place, but rather have a “who done it routine.” Their focus is on finding perpetrator traces with the risk of missing important information at the start of the investigation. Furthermore, identification information was mostly integrated in their final scenarios when the results of the analysis matched their expectations. CSIs have the tendency to look for confirmation, but the technology has no influence on this tendency. CSIs should be made aware of the risks of this strategy as important offender information could be missed or innocent people could be wrongfully accused.     

Communal schools and teacher victimization

Despite data showing that teacher victimization is at least as great a problem as student victimization, far less research exists regarding teacher victimization than student victimization and overall school crime, particularly with regard to the application of criminological theory to explain the victimization of teachers. We address this gap by examining the hierarchical relationship between communal school organization and teacher victimization in a nationally representative sample of 37,497 teachers from 7,488 public schools in the United States. Results showed that teacher experienced less victimization in schools that were more communally organized. We discuss these findings and present implications for school-based delinquency prevention.     

Reconceptualising parental monitoring within a model of goal-directed parental action

The concept and operationalisation of parental monitoring in adolescent behavioural research is idiosyncratic, and often conflates multiple concepts. This hinders study and understanding of its role in the distinct processes of adolescent development and behaviour. This paper introduces a model of Goal-Directed Parental Action, applied to adolescent crime, in order to situate and thus define the concept of parental monitoring. This model draws on Situational Action Theory to both prioritise motivation and specify a parental action process. This process distinguishes parental goals from the means by which to achieve them and from the knowledge gathering required to evaluate progress towards such goals. Within this framework, parental monitoring is defined as the employment of active information-gathering behaviours by parents to help them to gain knowledge about and evaluate their child's progress towards a range of parentally selected developmental and behavioural goals. In addition to facilitating this definition of parental monitoring, the model of Goal-Directed Parental Action has future potential to clarify other parenting concepts and processes.     

The Jack the Ripper murders: a modus operandi and signature analysis of the 1888–1891 Whitechapel murders

A number of females, commonly recognized as 11 victims, were murdered in separate events in Whitechapel, London between 1888 and 1891. An evaluation of the murders revealed that six of those murders were linked by a number of distinct, personal signature characteristics, including picquerism, overkill, incapacitation, domination and control, open and displayed, unusual body position, sexual degradation, mutilation, organ harvesting, specific areas of attack, preplanning and organization, and a combination of signature features. The signature characteristics observed in these infamous Jack the Ripper murders were compared to a 1981–1995 cohort of 3359 homicide cases from Washington State's HITS database. The analysis revealed that the signature displayed in six of the Whitechapel murders was extremely rare. There were only six records of female victims, one a prostitute, with probed, explored, or mutilated body cavities. There were only two cases, both females who were not prostitutes, where the body was left in an unusual position and body cavities were explored, probed, or mutilated.
