scholarly journals Behavioural Consistency and Offender Characteristics: Investigating Modus Operandi Patterns in Serial Stranger Sex Offences

Author(s):

Case linkage is a statistical technique which connects multiple sexual assault cases to a single perpetrator and holds promise for informing criminal investigations. Further, examining the behaviours executed most consistently across serial offences committed by a given offender is crucial to linking offences. The current study investigated behavioural consistency in a sample of 49 male serial stranger sexual offenders responsible for 147 offences. For each offence, four crime aspects were identified: 1) pre-crime facilitators, 2) victim selection and characteristics, 3) approach and attack methods, and 4) crime scene characteristics. Consistency between and within each crime series and across offender types based on background characteristics was examined. Results indicated a high degree of behavioural consistency across all crime aspects. Behaviours occurring prior to the offence were particularly useful in establishing consistent offending patterns. The implications of these findings in the context of police investigations and their utility for clinical practice are discussed.

Objective:This study reassesses the generational disparity in immigrant offending. Patterns and predictors of offending are compared using traditional peer-based models and an alternative within-family (parent–child dyad) model.Method:The National Longitudinal Survey of Youth (1979; NLSY79) and NLSY-Child and Young Adult (NLSY_CYA) data are merged to create an intergenerational data set to compare generational disparities in immigrant offending across peers and within families. Differences in self-reported offending (prevalence and variety) by immigrant generation are assessed using a combination of descriptive analyses (χ2and analysis of variance) and regression models.Results:While NLSY_CYA children generally are at a greater risk of offending compared with the NLSY79 mothers, the difference in offending is greatest between first-generation mom and second-generation child dyads. Disparities in offending are driven in large part by exceedingly low levels of offending among first-generation immigrants.Conclusion:Although the factors driving an increase in offending between parent–child generations are not unique to immigrants, they are amplified in immigrant families. Whereas the second generation is remarkably similar to their U.S.-born counterparts in terms of their involvement in crime, suggesting a high degree of swift integration, the greater involvement in crime among the children of immigrants compared to their foreign-born mothers suggests a decline in well-being across successive generations.

This essay starts by discussing the initial police involvement with newly reported sexual offences, covering local policing, problems with reporting to the police, police attitudes to complainants, and the role of sexual assault referral centres. The next section reviews police investigations of sexual offences, evidence gathering, and the role of forensic science and preparation for prosecution decisions. The author then explores the new role given to the police in their public protection role. This requires the police to take on supervisory activities, including administering the sex offender registry, applying for preventive civil orders, and disseminating information on sex offenders. The essay concludes by looking at the national and international policing of sexual offenders, including the policing of ‘sex tourism’.

En la Grecia y Roma clásicas, en donde cimientan los fundamentos estructurales de nuestra actual civilización, van a otorgar la más alta consideración al ser humano dedicado al desarrollo del intelecto, con un otium encaminado al cultivo de la mente y dedicado a una ocupación relacionada con algún ámbito del saber que requiera el uso del conocimiento y el dominio de una lex artis —no obstante, adquiere también relevancia el cultivo del cuerpo, pero, por lo general, en aras de una correcta instrucción militar, al objeto de prestar servicio, si fuere necesario, en defensa de la comunidad o sociedad—. La Roma clásica, que absorbe el pensamiento de los filósofos griegos —sobre todo, el arte de la retórica y la elocuencia—, a semejanza de la propia Grecia, distinguirá aquellos trabajos manuales, dependientes y serviles, que Cicerón califica como viles, en los que para su realización, por regla general, se imprime esfuerzo físico y para los que, en algunos casos, se requiere el dominio de un arte, pero que, en otros, ni tan siquiera se precisa el conocimiento previo de técnica alguna —o, de necesitarse, se trataría de un mínimo modus operandi—, de aquellas otras actividades en las que, para su fiel desempeño, es imprescindible poseer rigurosos conocimientos teóricos y prácticos, por lo que traen consigo una considerable carga intelectual, así como, en su ejecución, se caracterizan por su autonomía, lo que implica alto grado de libertad e independencia. Estas notas, que han perdurado a lo largo de la historia, en la actualidad continúan funcionando como elementos que, al valorarse en su conjunto, distinguen a las denominadas en la actualidad profesiones liberales del resto de profesiones, oficios u ocupaciones.In classical Greece and Rome, where the foundations of our present civilization were laid, they regarded most highly human beings dedicated to developing their intellect, with an otium intended for the cultivation of the mind and dedicated to an occupation associated with a field of knowledge that requires the use of expertise and the mastery of a lex artis —although the cultivation of the body also acquires importance for the purpose of correct military instruction to serve in defense of the community or society if needed—. Classical Rome, which absorbed Greek philosophy —especially the rhetorical art of eloquence—, like Greece itself, made a distinction between manual, dependent and servile labor, which Cicero considered base, which require physical force as a general rule and which in some cases also require the mastery of an art, but in other do not even demand prior knowledge of a technique —and if they do it would be merely a modus operandi—, and other activities where it is indispensable for their correct practice to possess rigorous theoretical and practical knowledge. The latter entaila considerable intellectual onus, and their practice is characterized by autonomy, which implies a high degree of freedom and independence. These features, which have continued throughout history, currently continue to function as elements which, if taken as a group, set apart in the present day the liberal professions from the rest of professions, trades or occupations.

In the UK, decisions to approve adoptive parents and foster carers and authorise adoptions rest with specialist panels. While their formal role and function are clear, there is concern that their composition and the biographies and background characteristics of members could introduce bias and influence the decisions made. This article examines the validity of these criticisms with findings from a study of eight agencies, 15 panels and 22 members. It was found that the panel system achieves its aims in terms of having a representative constitution and providing considered recommendations in a timely manner to senior managers, but that individual biography affects panel members in carrying out their role to an unexpectedly high degree, possibly leading to flawed decisions. Actions to remedy this problem, at both an individual and group level, are suggested.
