Visualizing Homicide: A Research Note

This paper provides some examples of the utility of graphical methods in analyzing data. While such methods are not expected to supplant standard statistical techniques, they can help the researcher in understanding characteristics of the process in ways that cannot be replicated using the standard methods.     

Traffic accident vs homicide: The contribution of DNA analysis to clarify this mystery. A case report

A marriage procession was going through the road when the vehicle met with a fatal accident and the wife of the driver died. The autopsy revealed lesions according with fatal traffic accident. But, a second autopsy revealed that there were injuries, but it was not reported in the first autopsy protocol. We analyze several autosomal STRs to typify some evidences collected inside the vehicle of traffic accident which were stained by the blood of the woman mortal victim. The results of the analysis of DNA suggested that the victim bled inside the vehicle and died and then, she was placed on the pavement and her husband simulated an accident.     

Barriers to safety* for victims of domestic homicide

ABSTRACT

Research on domestic homicide has focused on risk factors presented by perpetrators such as prior violence, threats to kill, stalking, access to weapons, mental health concerns, controlling behaviour and separation. However, there has been less focus on the barriers that victims face regarding finding support, increasing personal safety and decreasing violence and risk of homicide. The present study explored 20 potential barriers that female domestic homicide victims faced using 183 cases occurring between 2002 and 2012 from the Ontario (Canada) Domestic Violence Death Review Committee to examine the presence and frequency of these barriers within the sample. Using two-step cluster analysis, different profiles of barriers were identified that centred on victims’ fear, social isolation and mental health. The study is limited in being a post hoc analysis of homicides and no causal links can be made. The implications of this finding are discussed in the context of risk assessment, risk management and safety planning.     

Murder in the shadows: evidence for an institutional legitimacy theory of crime

The focus on the institutional control of violent crime has increased over the past few decades, stimulated largely by Messner and Rosenfeld’s “institutional anomie theory.” A related theory, referred to as “institutional legitimacy theory” in this study, has received considerably less attention. This theory, originating in the social control theoretical tradition, is tested in an analysis of homicide rates (circa 2012) across 108 nations. Overall, institutional legitimacy theory receives support as economic, political, familial, and religious institutional legitimacy assist in reducing homicide rates across societies. Most notably, homicide is positively associated with the size of the shadow economy (the measure of waning economic institutional legitimacy), consistent with the hypothesis that parties lacking institutional redress are more likely to use unilateral violence to resolve grievances.     

Homicide during teenage years--the ten year Metro-Dade County experience from 1973 to 1982

This article studies teenage homicide victims in Metro-Dade County, Miami, FL, U.S.A., between the years 1973 through 1982. A total of 263 cases were selected. Cases were then analyzed with respect to age, race, sex, cause of death, scene circumstances, alcohol and drugs detected at autopsy. A discussion follows that highlights these parameters from the standpoint of adolescence and the changing modern society.     

从侦查认识论的角度解读“命案必破”

“命案必破”是公安部在全国侦破命案工作会议上提出的命案侦破的努力方向,其出发点是鉴于目前重特大刑事案件侦破率低的情况,号召全国公安机关加大对命案的侦破力度,给犯罪分子以震慑,维护社会稳定。从侦查学的基础理论——侦查认识论的角度来解析“命案必破”,肯定其积极意义的同时,指出命案必破的含义应着眼于“命案必须全力侦破”,强调侦破应建立在实事求是的基础上,将“命案必破”与破案质量挂钩。     

对“命案必破”的思考

命案侦破是当前公安机关的一项重要任务,但目前对此仍存在一些片面认识。应正确认识命案侦破的重要意义,坚定“命案必破”的信心,进一步推进侦查破案工作,确保命案侦破工作取得有效成果。     

A Comparison of Methods for Analyzing Criminological Panel Data

We demonstrate that fixed- and random-effects models for pooled cross-sectional and time series data, and latent growth curve models for panel data are special cases of a more general model. We compare the estimates obtained from each type of model for a data set consisting of homicide rates and a vector of explanatory variables for 400 US counties over a 15-year period. Most, but not all, estimates are similar in the two models. We identify circumstances under which one approach may be advantageous to the other.

Crime is the Problem: Homicide,Acquisitive Crime,and Economic Conditions

A question that emerges from recent research on the relationship between economic conditions and street crimes committed for monetary gain concerns the effect of changing economic conditions on violent crime. I propose that the economy stimulates violent crime indirectly through its effect on acquisitive crime. This hypothesis is evaluated in fixed-effects panel models of change in acquisitive crime and homicide rates between 1970 and 2006. The analysis indicates that collective perceptions of economic conditions have a significant effect on an index of acquisitive crime and an indirect effect, through acquisitive crime, on homicide. Consistent with this result, the effect of collective economic perceptions is stronger for felony than argument-related homicides. A promising focus for future research is the role of underground markets in the production of both property and violent crime.

A study of amnesia in homicide cases and forensic psychiatric experts' examination of such claims

About one third of defendants in homicide cases claim amnesia during the time of their alleged act. Examining the authenticity of claimed amnesia is a special challenge for forensic experts. Because the experts' conclusions have legal implications, it is useful to study the characteristics of defendants who claim amnesia regarding a homicidal act and how forensic experts assess these defendants' claims. The forensic psychiatric reports from 2001 to 2007 on 102 Norwegian defendants charged with homicide were assessed quantitatively with a structured rating form. Due to multiple comparisons p of .003 was chosen. Twenty-six defendants claimed partial and 17 claimed total amnesia. No significant differences in the characteristics of the defendants were found between the partial, total, and no amnesia claiming groups. Claims of partial or total amnesia did not change the procedures and content of the forensic experts' examination. A memory test was applied in only one case. Despite the seriousness of the crime and the difficulty of assessing amnesia, the experts did not apply psychological testing of memory function or appropriate tests of possible malingering. Guidelines or standardized procedures for evaluation of defendants who claim amnesia should be developed. This could eventually contribute to more reliable and valid evaluations by forensic experts and increase the probability of just court outcomes.
