Homicide clearance: Discretionary and non-discretionary factors
Previous studies have produced mixed findings regarding discretionary and non-discretionary factors associated with the likelihood of homicides being cleared. Performing Pearson’s χ2 test, logistic regressions, and random forest analyses on all homicide cases that occurred in Italy in 2014, we assess if factors pertaining to the discretionary domain – that is, nationality, age, sex, socioeconomic status of the victim, previous convictions – and non-discretionary factors – for example, weapon, location, circumstance – are correlated with the outcome of the investigation. The empirical analysis does not identify relations between victims’ nationality, socioeconomic status, previous criminal records and homicide clearance. On the other hand, homicides whose victim is male are less likely to be cleared. While high media coverage correlates with a higher clearance rate, low media coverage is not correlated with the homicide case remaining unsolved. Finally, especially in Southern Italy where mafia organizations are more entrenched, homicides committed in a criminal environment have a lower chance of being cleared. With respect to Italy, the results indicate a lack of support for the discretionary perspective that argues’ that police may use discretion in clearing homicide cases according to the sociodemographic characteristics of victims.
期刊介绍:
The European Journal of Criminology is a refereed journal published by SAGE publications and the European Society of Criminology. It provides a forum for research and scholarship on crime and criminal justice institutions. The journal published high quality articles using varied approaches, including discussion of theory, analysis of quantitative data, comparative studies, systematic evaluation of interventions, and study of institutions of political process. The journal also covers analysis of policy, but not description of policy developments. Priority is given to articles that are relevant to the wider Europe (within and beyond the EU) although findings may be drawn from other parts of the world.
