Chapter
Solving sex crimes can be difficult. It is especially difficult to solve a sex offense case if there is no clear relationship between the victim and the offender. In those cases, one of the first questions that arises in the investigation is where to locate the offender. As many sex offenses that are committed by offenders with no clear link to the...

The present study examined whether there are different processes operating in the crime location choices between body‐disposing and non‐body‐disposing serial killers and between sexual serial killers and acquisitive serial killers. A sample of 49 series of solved German serial killings is used to examine the differences in travelled distances betwe...

Purpose To conduct a test of the principles underpinning crime linkage (behavioural consistency and distinctiveness) with a sample more closely reflecting the volume and nature of sexual crimes with which practitioners work, and to assess whether solved series are characterized by greater behavioural similarity than unsolved series. Method A sampl...
Experiment Findings

In three neighborhoods in the city of Amstelveen, the Netherlands, an experiment with near repeat patrolling after a burglary was implemented, during the 4th quarter of 2011. After a burglary had been reported to the police, two uniformed police officers were patrolling in a radius of 250 meter during two days from 7 am-11 pm. Though the near repea...

Purpose: This study compared the utility of different statistical methods in differentiating sexual crimes committed by the same person from sexual crimes committed by different persons. Methods: Logistic regression, iterative classification tree (ICT), and Bayesian analysis were applied to a dataset of 3,364 solved, unsolved, serial, and apparent...
Chapter

In this chapter we address the issue of contagiousness of burglaries. We state that the process of contagiousness (i.e. repeat and near-repeat victimization) might be influenced by some offenders committing 'runs' of crimes. A run is defined as multiple crimes in sequences within a short time frame, at maximum a couple of hours, and within a limite...

OPINIE De discussie over een DNA-databank met de gegevens van alle Nederlanders is - voorspelbaar - losgebarsten sinds de aanhouding van Jasper S., de verdachte in de zaak-Vaatstra. Zonder naar de daadwerkelijke mogelijkheden van DNA voor de opsporing te kijken, is het echter weinig relevant om over privacy en andere mogelijke voor- of nadelen...
Article
The present study examines consistency of crime behaviour among 347 sexual assaults committed by 69 serial sex offenders. This individual behaviour approach—the so-called signature approach—reveals which features of crime behaviour are consistent across a series and which features are not. The consistency scores were calculated using the Jaccard's...

Can a fruitful police surveillance scheme be based on supposedly increased risk immediately after and around a previous burglary (‘near repeat phenomenon’)? An experiment in Amstelveen has been set up and analysed for this purpose. Some neighbourhoods got a ‘near repeat surveillance’ scheme, and the occurrence of burglary in those areas has been co...

Offender profiling is based on the notion that the crime scene and the behaviour displayed during the commission of the crime, reflect the characteristics of the offender. A growing body of research shows that the assumptions underlying profiling may not be empirically valid. On the other hand, research focussing on actual behaviour, such as the ge...

Purpose – The purpose of this paper is to assess the possibilities of formulating risk behavior characteristics to determine a guest's risk category on money laundering in casinos. Design/methodology/approach – A total of 148 guests (27 women and 121 men) and their registered events (1,184 events) are analyzed by using a form of canonical correlati...
Chapter
Criminology is the scientific discipline that studies the phenomena of crime and delinquency. Criminology has links to other sciences like biology, sociology, psychology, policing and geography. As early as the beginning of the 19th century, criminologists became aware of spatial patterns in criminal behaviour. By mapping crime rates, these studies...

In oktober 1985 werd Marijke Medens met messteken om het leven gebracht bij het benzinestation in Warnsveld. Destijds liep het onderzoek dood, maar in 2001 kwam er nieuwe informatie binnen bij de geheime politie. Daaruit moest blijken dat Mick van Bezemer de moord pleegde, samen met een aantal anderen. Hun namen zouden vermeld staan in een mysterie...

Geographical profiling is an investigative technique that analyzes the spatial pattern of a related series of crime locations in order to predict the location of the offender’s residence. After explaining how today’s geographical profiling works, it is argued that such profiling may be improved if characteristics of the offense, the offender, and g...
