Geophysical Monitoring of Simulated Clandestine Graves Using Electrical and Ground‐Penetrating Radar Methods: 0–3 Years After Burial*,†

Abstract: This study provides forensic search teams with systematic geophysical monitoring data over simulated clandestine graves for comparison to active cases. Simulated “wrapped” and “naked” burials were created. Multigeophysical surveys were collected over a 3‐year monitoring period. Bulk ground resistivity, electrical resistivity imaging, multifrequency ground‐penetrating radar (GPR), and grave and background “soil‐water” conductivity data were collected. Resistivity surveys revealed the naked burial had consistently low‐resistivity anomalies, whereas the wrapped burial had small, varying high‐resistivity anomalies. GPR 110‐ to 900‐MHz frequency surveys showed the wrapped burial could be detected throughout, with the “naked” burial mostly resolved. Two hundred and twenty‐five megahertz frequency GPR data were optimal. “Soil‐water” analyses showed rapidly increasing (year 1), slowly increasing (year 2), and decreasing (year 3) conductivity values. Results suggest resistivity and GPR surveys should be collected if target “wrapping” is unknown, with winter to spring surveys optimal. Resistivity surveys should be collected in clay‐rich soils.     

DEET (N,N‐Diethyl‐meta‐toluamide) Induced Delay of Blowfly Landing and Oviposition Rates on Treated Pig Carrion (Sus scrofa L.)

Abstract: The question of whether the insect repellent N,N‐Diethyl‐meta‐toluamide (DEET) affected fly attraction, oviposition, and larval development was investigated; in part, to determine whether the common habit of wearing DEET as a repellent could affect the rate of human decomposition. Experiments using pig surrogates of human decedents were carried out in a rural environment. Dead piglets were sprayed with DEET, and fly behavior, colonization levels, and maggot development were compared with those in nonsprayed controls. Piglets treated with DEET experienced significant delays in fly visitation and oviposition and delayed appearance of each larval instar, as well as reduced total larval numbers (p < 0.01 for all variables), with subsequently reduced decomposition (p < 0.05). Such changes in fly behavior and larval population development would significantly impact the estimation of the period following the death from entomological evidence in decedents wearing DEET at the time of their death.     

Book review essay

Prior research into the effects of racial diversity on workplace relationships has demonstrated that white workers prefer to work in and with groups which are also composed of white workers. Using structural equation models, we tested whether higher levels of racial diversity, measured as social distance from coworkers and inmates, were associated with lower evaluations of organizational commitment, teamwork among coworkers, and efficacy in dealing with inmates. We found the expected negative effects of racial diversity on white male correctional workers for organizational commitment, but not for teamwork and efficacy. For minority male correctional workers, racial diversity did not affect organizational commitment, teamwork, or efficacy.     

Mismeasuring Militias: Limitations of Advocacy Group Data and of State‐Level Studies of Paramilitary Groups

The errors associated with measuring the number of militia and patriot groups may cast doubt on conclusions drawn from prior studies of the spatial variation of these movements. Most studies of militias have been qualitative investigations of a single group, state, or region. A growing number of studies, however, have used quantitative techniques to assess the hypothesis that the number of militia groups by state covaries with structural and cultural forces. We outline a number of concerns with the validity of the counts, conducted by the Anti‐Defamation League and the Southern Poverty Law Center, used by these studies. We re‐estimate models from previous studies using the four alternative measures of these groups employed in prior studies. We find that many inferences drawn for identical theoretical models differ based upon the measure used. These discrepancies apply not simply to tangential control variables but to indicators of key theoretical constructs. In other words, the decision as to whether or not a particular theoretical framework receives empirical support often depends upon which measure of the dependent variable is used. This suggests that the inconsistent findings in prior research may be due to measurement error and makes it difficult to assess the validity of the conclusions drawn from these studies. It is important to be aware of these weaknesses since scholars studying political crimes and related phenomena often use information from similar sources, making this specific example relevant to a more general area of research.     

Low Self‐Control and Contact with the Criminal Justice System in a Nationally Representative Sample of Males

Prior research on law enforcement and court system actions suggests that offender demeanor influences practitioner decision making. However, few studies have examined a key implication of this body of work—namely, criminogenic factors associated not only with offending but also with demeanor may result in a greater likelihood of contact with and formal processing by law enforcement and the courts. Using data from the National Longitudinal Study of Adolescent Health, we test the hypothesis that low self‐control, which is associated with a range of characteristics that might influence practitioner perceptions of individual offenders’ demeanors, will predict greater contact and formal processing. Briefly, we found that low self‐control was consistently related to criminal justice system involvement as measured by police contacts, arrests, age at first police contact, and arrest onset. The implications of the findings for theory and research are discussed.     

Gang Membership,Drug Selling,and Violence in Neighborhood Context

A prominent perspective in the gang literature suggests that gang member involvement in drug selling does not necessarily increase violent behavior. In addition it is unclear from previous research whether neighborhood disadvantage strengthens that relationship. We address these issues by testing hypotheses regarding the confluence of neighborhood disadvantage, gang membership, drug selling, and violent behavior. A three‐level hierarchical model is estimated from the first five waves of the 1997 National Longitudinal Survey of Youth, matched with block‐group characteristics from the 2000 U.S. Census. Results indicate that (1) gang members who sell drugs are significantly more violent than gang members that don’t sell drugs and drug sellers that don’t belong to gangs; (2) drug sellers that don’t belong to gangs and gang members who don’t sell drugs engage in comparable levels of violence; and (3) an increase in neighborhood disadvantaged intensifies the effect of gang membership on violence, especially among gang members that sell drugs.     

Family Group Conferencing and Re‐Offending Among First‐Time Juvenile Offenders: The Indianapolis Experiment

Restorative justice processes, and family group conferences in particular, have become increasingly common in justice system practices across the globe. There has also been significant scholarly interest. Yet, with several notable exceptions, much of the research has been characterized by relatively weak designs, and questions related to the impact of family group conferences on re‐offending remain unanswered. This research is intended to begin to address these issues. The study is based on an experiment conducted in Indianapolis, Indiana whereby young, first‐time‐offending youths were randomly assigned to either a family group conference or one of a number of court‐ordered diversion programs. Nearly 800 youths participated in the experiment, and the cases were tracked for 24 months following their initial arrest. Survival analysis techniques were used to compare prevalence patterns of re‐offending among the treatment and control groups. The results indicated a significant difference between the two groups with the control group experiencing higher rates of failure (re‐offending). The differences were most pronounced during the period of 3–8 months following the initial arrest. Incidence rates were also compared. Assignment to the treatment group was negatively related to incidence of offending. Given the consistent finding of victim benefits in restorative justice processes, the results suggest that conferences hold promise as an effective intervention, at least for young first‐time offenders, and warrant continued experimentation.     

A Hero’s Welcome? Exploring the Prevalence and Problems of Military Veterans in the Arrestee Population

The potential for veterans to end up in the criminal justice system as a result of physical and psychological problems that may be combat‐related has generated much interest, illustrated most recently by the development of specialized veterans’ courts. However, little is known about how often veterans are arrested and incarcerated, the nature of their problems, or the extent to which their military service has contributed to their criminality. Using interview data from 2,102 arrestees booked in Maricopa County (AZ) during 2009, this paper examines the problems and prior experiences of arrested military veterans and compares veteran and non‐veteran arrestees along a range of measures. Results indicate that veterans comprise 6.3% of the arrestee population, and that more than 50% of veterans report suffering from at least one combat‐related problem including physical injury, post‐traumatic stress disorder (PTSD), other mental health problems, and substance abuse. Multivariate analysis indicates that veteran arrestees differ from non‐veterans on a number of key measures, most notably more frequent arrests for violent offenses and greater use of crack cocaine and opiates. The paper concludes with a discussion of implications for the potential link between military service and criminality as well as for criminal justice policy and practice.     

Prevalence and Characteristics of Co‐Offending Recruiters

Previous examinations of co‐offending have identified a subset of high‐rate offenders who commit crimes with a large number of co‐offenders, most of whom are younger and less criminally experienced. These so‐called “recruiters” are of particular interest to researchers and practitioners, because of their potential role in facilitating offending onset and recidivism among their co‐offenders. In this paper, data on 61,646 individuals detected by a large UK police force are used to identify offenders who fitted the recruiter profile, and to compare their individual and offending characteristics with those of non‐recruiters. In total, 86 recruiters were identified. In multivariate analyses, recruiters were found to be older than non‐recruiters and were typically involved in property crimes. In addition, they tended to offend in criminal groups that were more heterogeneous and stable than non‐recruiters. These findings suggest that a small but identifiable group of recruiters can be detected using official data and that these individuals may be important targets for police attention and court treatment.
