Fatal descent from height in New York City

All deaths due to descent from height that underwent autopsy at the Manhattan Office of Chief Medical Examiner of New York City over a two year period (1997-1999) were reviewed. The scene and autopsy findings, psychiatric history, and toxicology results were examined. There were 120 deaths: 77 suicides, 36 accidents, 5 undetermined, and 2 homicides. Psychiatric illness was reported in 86% of suicides. The toxicological detection of psychiatric medications supports the high percentage of psychiatric disease in the suicide group. In the accidental group, the detection of ethanol and illicit drugs was higher (36%) than expected from the case investigation and similar to the suicide group (29%). Accidental falls by women made up fewer than 3% of all manners. Due to the variation in the extent of injuries, it is unwise to attempt to conclude how high a person descended based on the autopsy findings. Descents into water commonly have minimal findings on external examination with marked internal injuries. The methods of investigation and criteria for death certification using the study results are discussed.     

Truancy Intervention Reduces Crime: Results from a Randomized Field Trial

Educational attainment is a fundamental cornerstone to success throughout the life-course. As a result, ensuring that young people remain in school and are not truant is critical. Although the importance of truancy as a risk factor for many adverse outcomes, including crime, has been well-documented, much less methodologically rigorous work has been undertaken to evaluate potentially promising prevention and intervention strategies. This paper uses a randomized field trial method to test how a partnership between police and schools targeting truancy impacts offending in a sample of high-risk truanting young people. We find that the truancy intervention reduces offending and we discuss the implications for practice and directions for future research.     

Judicial Independence: Evidence from a Natural Experiment

In this article, we directly test the presence of judicial independence by examining judicial recess appointees who have later been confirmed by the Senate to full‐time Article III judicial positions. Specifically, we compare the votes of recess‐appointed courts of appeals judges during their temporary appointment tenure with a similar period following Senate confirmation. We find substantial differences in pre‐ and postconfirmation voting, suggesting that the structural protections of the Constitution provide judges a certain amount of independence.     

Students' Fear After Columbine: Findings from a Randomized Experiment

On April 20, 1999, the most deadly act of school violence in the United States occurred at Columbine High School. Public perceptions and media accounts suggested that fear of victimization at school greatly increased after Columbine. The actual response is unknown. The 1999 School Crime Supplement to the National Crime Victimization Survey provides a unique opportunity to study Columbine's effect on students' fear. Experimental conditions were approximated by the NCVS sampling design that randomly allocated the 12- to 18-year-old student-respondents to pre- and post-April 20 groups. Contrary to expectations, students were only slightly more fearful after Columbine. An initial explanation for this finding is explored. As little is known about fear following highly publicized incidents of extreme violence such as Columbine and the terrorist attacks of September 11, 2001, this research provides an essential foundation for further study and theoretical development in this largely-ignored area of fear.     

Phencyclidine: a 5-year retrospective review from the New York City Medical Examiner's Office

We report here a 5-year retrospective review of autopsy cases from the New York City Medical Examiner's Office that demonstrated phencyclidine (PCP) in the blood. There were a total of 138 cases. There were 52 deaths because of mixed drug intoxication: the blood PCP concentrations in these cases ranged from <1 to 598 ng/mL. There were 80 violent deaths in which PCP was quantified in the blood but was unrelated to the cause of death. There were five nonviolent deaths in which PCP exclusively was detected. In four of these, there were preexisting medical conditions that could also have contributed to death. In these, the highest PCP concentration was 361.3 ng/mL, a concentration lower than seven of the individuals in our violent death category. This suggests that lower concentrations may be fatal with comorbid conditions.

The Effect of Incarceration on Re-Offending: Evidence from a Natural Experiment in Pennsylvania

Objectives

This paper uses a sample of convicted offenders from Pennsylvania to estimate the effect of incarceration on post-release criminality.

Methods

To do so, we capitalize on a feature of the criminal justice system in Pennsylvania—the county-level randomization of cases to judges. We begin by identifying five counties in which there is substantial variation across judges in the uses of incarceration, but no evidence indicating that the randomization process had failed. The estimated effect of incarceration on rearrest is based on comparison of the rearrest rates of the caseloads of judges with different proclivities for the use of incarceration.

Results

Using judge as an instrumental variable, we estimate a series of confidence intervals for the effect of incarceration on one year, two year, five year, and ten year rearrest rates.

Conclusions

On the whole, there is little evidence in our data that incarceration impacts rearrest.     

Bodies found in the waterways of New York City

We reviewed the case records for all decedents recovered from the waterways of New York City over a three year period (1997-2000). The epidemiological profile, circumstances, toxicology findings, putrefactive changes, date of recovery, length of immersion, and injuries were examined. There were 123 deaths: 52 suicides, 50 undetermined, 16 accidents, and five homicides. The causes of death included: 97 drownings, 13 undetermined, and 13 other. Of all the floating decedents, 27% were without putrefactive change. All found after two or more weeks of immersion were recovered from November to May. The detection of ethanol and illicit drugs was 53% in the accident, 41% in the suicide, and 33% in the undetermined groups. Detection of ethanol and/or drugs of abuse is not a reliable criterion to distinguish suicide from accident. The identification of the deceased is pivotal for determining the manner of these deaths. Therefore, a great reliance is placed upon the medical investigator and the police (including the missing persons bureau) to determine the circumstances and identification of the decedent.     

Recruitment of female police officers in New York City

As part of a larger study, forty-two female police officers in New York City were asked to articulate their motivations for selecting police work as a career. The reasons given are presented, and comparisons are made with the reasons given in the few other studies of male and female officers. It is felt that a better understanding of the motivations behind this career choice will help the police agencies recruit more effectively and more appropriately select candidates for openings.     

The dragon breathes fire: Chinese organized crime in New York City

Although it is widely acknowledged that Chinese businesses are victims of extortion by Asian youth gangs, there is no reliable information to examine the patterns and social processes of the problem. This paper explores the structure of extortion and other forms of victimization based on surveys of (N=603) Chinese-owned businesses in three Chinatown neighborhoods in New York City. It focuses on the nature of Chinese crime groups, social contexts of gang extortion, social processes of victimization, and merchants' compliance or resistance to gang demands. Finally, the paper discusses the problems and prospects of Chinese criminality in America.Support for this research was provided by Grant 89-IJ-CX-0021 from the National Institute of Justice.

Defensive Gun Uses: New Evidence from a National Survey

The number of civilian defensive gun uses (DGUs) against criminal attackers is regularly invoked in public policy debates as a benefit of widespread private ownership of firearms. Yet there is considerable uncertainty for the prevalence of civilian DGUs, with estimates ranging from 108,000 (using the National Crime Victimization Survey) to 2.5 million (using smaller telephone surveys) per year. In this paper we analyze the results of a new national random-digit-dial telephone survey to estimate the prevalence of DGU and then discuss the plausibility of the results in light of other well-known facts and possible sources of bias in survey data for sensitive behaviors. Because DGU is a relatively rare event by any measure, a small proportion of respondents who falsely report a gun use can produce substantial overestimates of the prevalence of DGU, even if every true defensive gun user conceals his or her use. We find that estimates from this new survey are apparently subject to a large positive bias, which calls into question the accuracy of DGU estimates based on data from general-population surveys. Our analysis also suggests that available survey data are not able to determine whether reported DGU incidents, even if true, add to or detract from public health and safety.     

Identifying Classes of Explanations for Crime Drop: Period and Cohort Effects for New York State

Objective

This paper advances current understanding of the contemporary crime drop by focusing on the changes in the age distribution of arrests from 1990 to 2010. Using the New York State Computerized Criminal History (CCH) file, which tracks every arrest in the state, we apply standard demographic methods to examine age-specific arrest rates over time. We test whether the 25 % drop in the felony arrest rate can be best explained by period or cohort effects with special attention to how the phenomenon varies across crime types and regions within the state.

Methods

Following the analytic approach of O’Brien and Stockard (J Quant Criminol 25(1):79–101, 2009), we fit the age–period–cohort (APC) model using the generalized inverse matrix, which creates an estimable model. We partition the model variation into each factor by subtracting the variation of the two-factor model from the variation of the three-factor model to provide a direct comparison of the two different classes of explanations for crime drop: period and cohort.

Results

Our analysis supports a cohort explanation over a period explanation. Controlling for the (substantial) variation due to age, the cohort effect accounts for twice as much of the remaining variation as the period effect. Specifically, the drop in arrest rates is concentrated in more recent birth cohorts across all ages. Although we found statistically significant age–period interaction effects for the younger age group (ages 16–20) in 1990 and 1995, the cohort effect was still a much stronger predictor of felony arrest rates than the period explanation, even with the age–period interaction.

Conclusions

The current study reports that the overall drop in felony arrest rates from 1990 to 2010 is mostly due to decreased arrests among those who were born after 1970 rather than a universal drop across different age groups. We discuss but do not test two potential explanations—the legalization of abortion and the ban on leaded gasoline—for the underlying factors associated with a different criminal propensity among birth cohorts.

     

Crime trends and the effect of mandated drug treatment: Evidence from California's Substance Abuse and Crime Prevention Act

The Substance Abuse and Crime Prevention Act (SACPA), implemented statewide in California in July 2001, mandates drug treatment rather than incarceration for certain nonviolent drug offenders. Critics of the legislation suggest that crime increased as a result of the legislation, but researchers have largely ignored this issue. Utilizing time series methodology applied across several independent data sets from Orange County, California, the effects of SACPA on crime were assessed. Results indicate that significant increases in commercial burglaries and paraphernalia arrests may have been attributed to SACPA, but the overall pattern does not support a conclusion that crime increased markedly.     

Ten years of "body packers" in New York City: 50 deaths

We reviewed all 50 body packer deaths in New York City from 1990 to 2001. The majority (37/50) of deaths were caused by acute intoxications due to open or leaking drug packets in the gastrointestinal tract. The number of packets recovered ranged from 1 to 111 (average 46). The weight of the combined packets ranged from 9.4 to 1,200 g (average of 377). The age ranged from 19 to 57 years (mean 37.1). The decedents were: 82% male, 66% Hispanic, 24% Black, and 10% White. The manners of death were 47 accidents, 1 homicide, 1 natural, and 1 undetermined. The causes of death included 42 acute intoxications, 5 intestinal obstructions/bowel perforations, 1 gunshot wound, 1 intracerebral hemorrhage due to hypertensive disease, and 1 undetermined. Of the 50 decedents, 42 were transporting opiates, 4 cocaine, and 4 both opiates and cocaine. There were 9 deaths from 1990-1995 and 41 from 1996-2001. Of the 41 deaths between 1996 and 2001, only 6 involved cocaine. In New York City there has been an increase in body packer deaths from the early 1990s to the late 1990s. Along with this increase is a marked predominance of opiate body packer deaths with few cocaine deaths.     

Evaluating the Minnesota Comprehensive Offender Reentry Plan (MCORP): Results from a Randomized Experiment

Using a randomized experimental design, this study evaluated the effectiveness of the Minnesota Comprehensive Offender Reentry Plan (MCORP), an offender reentry pilot project implemented in 2008. In an effort to reduce recidivism, MCORP attempted to increase offender access to community services and programming by producing greater case management collaboration between caseworkers in prison and supervision agents in the community. The results showed that MCORP significantly improved employment rates, decreased homelessness, broadened offenders’ systems of social support, and increased the extent to which offenders participated in community support programming (mentoring, restorative justice services, and faith‐based programming). The findings further revealed that MCORP significantly reduced all three types of reoffending (rearrest, reconviction, and new offense reincarcerations) but did not have a significant impact on supervision revocations for technical violations. The evidence suggests that MCORP was effective in decreasing reoffending largely because it increased the extent to which offenders were employed, involved in community support programming, and able to develop systems of social support.
