Prison Homicide: An Extension of Violent Criminal Careers?

This study investigated prison homicide perpetrators through the lens of the career criminal perspective. Prison homicide, while a rare event, has critical implications for the prison environment. Despite its importance as a form of institutional violence that must be addressed, only four studies in the past five decades have explored the characteristics of homicide perpetrators/victims, the motives, and circumstances of the crime. The goal of the current study was to develop a better understanding of prison homicide by examining 54 perpetrators who committed 37 inmate homicides over 40 years in a mid-Western state prison system. Results showed that prison homicides typically involved a younger male inmate perpetrator, acting independently, murdering an older inmate, in his cell, by stabbing or beating the victim during an altercation. Perpetrators, in comparison with victims and prisoners in general, had a record indicating more prior community homicides, elevated institutional risk scores, and higher rates of serious and assaultive prison misconduct, all indicative of prior community and prison maladjustment. Consistent with career criminal research, prison homicide perpetrators constitute a small but distinct subset of habitually deviant criminals that perpetrate high rates of criminal and violent behavior regardless of context.

Examining Developmental Patterns of Prison Misconduct: An Integrated Model Approach.

Recent prison scholarship has employed an integrated model of the developmental/life-course perspectives and importation model to examine prison misconduct. Using longitudinal data from a large sample of inmates incarcerated in a U.S. prison system, this study attempts to validate and expand recent prison research by systematically examining the relationship among inmate characteristics and misconduct trajectories, particularly for the higher/chronic pattern of misconduct relative to other identified clusters. The results show that smaller groups of inmates have persistent criminal careers and continually engaged in high level of misconduct. In addition, several inmate characteristics associated with prison misconduct can also be useful to distinguishing high-risk inmates/persistent offenders from groups that offend at low rates over time. These findings could provide vital information to prison officials in developing and designing alternative prison services, assistance, and rehabilitation programs based on the misconduct trajectories.

Gender-responsiveness in corrections: Estimating female inmate misconduct risk using the Personality Assessment Inventory (PAI).

Proper inmate assessment is critical to correctional management and institutional security. While many instruments have been developed to assist with this process, most of these tools have not been validated using samples of female inmates although distinct gender differences have been identified in the inmate population in terms of adaptation and misconduct. The Personality Assessment Inventory (PAI) is a multiscale measure of psychopathology that is being increasingly utilized in the correctional setting to assist with the inmate classification process. The current study contributes to the dearth of literature surrounding gender-responsive inmate classification by utilizing a sample of 2,000 female inmates to examine the incremental and predictive validity of the PAI in association with general and assaultive disciplinary infractions. Findings from this study reveal that the PAI scales presenting the strongest relationship to general and assaultive disciplinary infractions among this female sample included Aggression (AGG), Antisocial Features (ANT), Paranoia (PAR), and the Violence Potential Index (VPI). Moreover, findings derived from this study suggest that certain PAI measures, specifically ARD-T, DRU, and more general substance abuse and mental health indicators may be useful in gender-responsive assessments during the female inmate classification process.

Testing the predictive validity of the Personality Assessment Inventory (PAI) in relation to inmate misconduct and violence.

The Personality Assessment Inventory (PAI) has been widely employed in correctional settings as a screening tool to assess inmates' risk for committing various types of institutional misconduct. Evaluations have generally found the PAI scales Antisocial Features (ANT), Aggression (AGG), and the Violence Potential Index (VPI) to be modestly related to institutional misbehavior, thus supporting its construct validity. The current study provides the most comprehensive examination of the predictive and incremental validity of the PAI and its subscales among a large sample of imprisoned offenders to date. In particular, the size of the sample (n = 15,546) and follow-up period (mean time at risk of 2.2 years) allowed for the disaggregation of institutional misconduct by levels of seriousness and separate examinations by conviction offense and criminal history variables. The 3 scales most strongly related to general rule infractions were ANT, AGG, and the VPI. After controlling for age at intake, violent conviction history, prior violent arrests, and time at risk, the PAI scales were shown to add incremental validity to the classification of 4 types of disciplinary infractions ranging from 2 to 4 percentage points. The study also explored the relationship of the PAI's response bias scales to institutional misconduct. (PsycINFO Database Record

Using base rates and correlational data to supplement clinical risk assessments.

The current study is a partial replication of previous studies designed to estimate the level of risk posed by capital murder defendants. The study draws on data describing the behavior of nearly 2,000 incarcerated capital murderers to forecast violence propensity among defendants sentenced to life imprisonment. Logistic regression is used to model various violence outcomes, relying on the following predictors: age, educational attainment, prior imprisonment, and gang affiliation. This exercise is designed to illustrate how actuarial data may be used to anchor individualized clinical assessments of risk in capital murder trials.

Youth pathways to placement: the influence of gender, mental health need and trauma on confinement in the juvenile justice system.

Although the juvenile crime rate has generally declined, the involvement of girls in the juvenile justice system has been increasing. Possible explanations for this gender difference include the impact of exposure to trauma and mental health needs on developmental pathways and the resulting influence of youth's involvement in the justice system. This study examined the influence of gender, mental health needs and trauma on the risk of out-of-home placement for juvenile offenders. The sample included youth referred to three urban juvenile probation departments in Texas between January 1, 2007 and December 31, 2008 and who received state-mandated mental health screening (N = 34,222; 30.1 % female). The analysis revealed that, for both genders, elevated scores on the seven factor-analytically derived subscales of a mental health screening instrument (Alcohol and Drug Use, Depressed-Anxious, Somatic Complaints, Suicidal Ideation, Thought Disturbance, and Traumatic Experiences), especially related to past traumatic experiences, influenced how deeply juveniles penetrated the system. The findings suggest that additional research is needed to determine the effectiveness of trauma interventions and the implementation of trauma informed systems for youth involved with the juvenile justice system.

Probability of criminal acts of violence: a test of jury predictive accuracy.

The ability of capital juries to accurately predict future prison violence at the sentencing phase of aggravated murder trials was examined through retrospective review of the disciplinary records of 115 male inmates sentenced to either life (n = 65) or death (n = 50) in Oregon from 1985 through 2008, with a mean post-conviction time at risk of 15.3 years. Violent prison behavior was completely unrelated to predictions made by capital jurors, with bidirectional accuracy simply reflecting the base rate of assaultive misconduct in the group. Rejection of the special issue predicting future violence enjoyed 90% accuracy. Conversely, predictions that future violence was probable had 90% error rates. More than 90% of the assaultive rule violations committed by these offenders resulted in no harm or only minor injuries.

Community violence to prison assault: a test of the behavioral continuity hypothesis.

This large-scale study (N = 23,277) investigated the relationship between criminal history in the community and serious or assaultive prison misconduct, while controlling for the effects of inmate characteristics, general criminality, and custody level. Community violence variables included the rate of prior violent crime arrests and the types of prior violent crime, as well as a range of specific violent crimes of conviction. Behavioral continuity from community to prison was neither simple nor intuitively discernible, depending on the type, recency, and pattern of community criminality. Application of logistic regression models revealed that the omnibus measure of the rate of prior violent arrests was not related to either serious or assaultive prison misconduct. Prior arrests for assault and current convictions for robbery and/or assault, but not prior or current homicides, were associated with an increased risk for prison violence. Current conviction for a sexual assault had the strongest inverse relationship to prison violence, while prior arrests for sexual assault showed no relationship to prison violence. A more "nuanced" approach in assigning risk ratings based on prior criminal history and seriousness of offense is recommended.

Life and death in the Lone Star State: three decades of violence predictions by capital juries.

The accuracy of three decades of Texas jury predictions of future violence by capital defendants was tested through retrospective review of the disciplinary records of former death row (FDR) inmates in Texas (N = 111) who had been sentenced to death under this "special issue" and subsequently obtained relief from their death sentences between 1989 and 2008. FDR inmates typically had extended tenures on death row (M = 9.9 years) and post-relief in the general prison population (M = 8.4 years). FDR prevalence of serious assault was low, both on death row (3.6%) and upon entering the prison population (4.5%). None of the assaults resulted in life-threatening injuries to the victims. Violence among the FDR inmates was not disproportionate compared with life-sentenced capital offenders. Consistent with other research, juror expectations of serious prison violence by these offenders had high error (i.e., false positive) rates. The confidence of legislators and courts in the violence prediction capabilities of capital jurors is misplaced.

Improbable predictions at capital sentencing: contrasting prison violence outcomes.

The postconviction prison disciplinary records of capital defendants (n = 73) who had been the subject of defense-sponsored violence risk assessments or risk-related testimony (1995-2007) that asserted an improbability of future serious prison violence were analyzed. During postconviction prison tenures averaging 4.4 years, none of the capital defendants was cited for accomplished serious assaults. The prevalence of misconduct was inversely related to severity: 54.8 percent were cited for some disciplinary misconduct, 27.4 percent for potentially violent disciplinary violations, 12.3 percent for assaultive misconduct, and 1.4 percent for attempted serious assault. Rates of misconduct among the capital offenders were equivalent to those among all inmates (n = 18,561, annual average) in high-security federal prisons (2001-2005). The accuracy rate of forecasts of improbability stands in sharp contrast to that of prosecution-sponsored expert testimony at capital sentencing that had asserted high rates of future violence.

Assertions of "future dangerousness" at federal capital sentencing: rates and correlates of subsequent prison misconduct and violence.

The federal prison disciplinary records of federal capital inmates (n=145) who were sentenced to life without possibility of release (LWOP) by plea bargain, pre-sentencing withdrawal of the death penalty, or jury determination were retrospectively reviewed (M=6.17 years post-admission). Disaggregated prevalence rates were inversely related to infraction severity: serious infraction =0.324, assaultive infraction =0.207, serious assault =0.09, assault with moderate injury =0.007, assault with major injuries or death =0.00. Frequency rates of misconduct were equivalent to other high-security federal inmates (n=18,561), regardless of infraction severity. Government assertions of "future dangerousness" as a nonstatutory aggravating factor were not predictive of prison misconduct. These findings inform federal capital risk assessments and have public policy implications for procedural reliability in death penalty prosecutions.

Capital offenders in Texas prisons: rates, correlates, and an actuarial analysis of violent misconduct.

This study analyzed the records of 136 recently incarcerated capital murder offenders in the initial phase (M = 2.37 years, range = 6-40 months) of their life sentences in the Texas Department of Criminal Justice. Prevalence rates of institutional violence were inversely related to severity: potentially violent misconduct (36.8%), assaultive violations (14%), serious assaults (5.1%), and homicides (0%). Consistent with prior studies, factors correlated with assaultive misconduct included age (inversely), prior prison confinement, and concurrent robbery or burglary in the capital offense. A simplified Burgess scale entitled the Risk Assessment Scale for Prison-Capital (RASP-Cap) was moderately successful in identifying varying levels of improbability of committing violence-related misconduct however defined (AUC = .715-.766).

Actuarial models for assessing prison violence risk: revisions and extensions of the Risk Assessment Scale for Prison (RASP).

An investigation and extension of the Risk Assessment Scale for Prison (RASP-Potosi), an actuarially derived scale for the assessment of prison violence, was undertaken through a retrospective review of the disciplinary records of the first 12 months of confinement of a cohort of inmates entering the Florida Department of Corrections in 2002 and remaining throughout 2003 (N=14,088). A near replication of the RASP-Potosi and additional analyses based on other weighted logistic regression models were performed on an inmate subsample for whom all information categories were available (n=13,341). Younger age and shorter sentences were associated with increased violent misconduct. Older age, drug conviction, and higher educational attainment were associated with reduced violent misconduct. Regardless of whether the original RASP-Potosi or its progeny were utilized, or the custody level of the inmate sample, the models were modestly successful in predicting prison violence, with the area under the curve (AUC) ranging from .645 to .707.

Is death row obsolete? A decade of mainstreaming death-sentenced inmates in Missouri.

Death-sentenced inmates in Missouri have been integrated or "mainstreamed" into the general population of the Potosi Correctional Center since 1991. By comparing the rate of violent misconduct among these mainstreamed death-sentenced inmates with that of the life-without-parole and parole eligible inmates under fully integrated conditions of confinement, this study provides the first empirical (statistical) evaluation of this innovative alternative to segregated death row confinement. The mainstreamed death-sentenced inmates committed no inmate or staff homicides, or attempted homicides. Comparison of their rates of institutional violence revealed frequencies that were similar to those of life-without-parole inmates, and well below those of fellow inmates who were sentenced to parole eligible terms. These findings cast serious doubt on the security-driven assumptions that have typified the segregation of death-sentenced inmates and have dictated highly restrictive confinement policies for this group. A conclusion that death-sentenced inmates can be safely integrated into a general prison population has significant implications for allocation of scarce fiscal resources and correctional staff, as well as for inmate mental health, particularly given the extended tenure that death-sentenced inmates typically serve between sentencing and relief/execution.

An actuarial model for assessment of prison violence risk among maximum security inmates.

An experimental scale for the assessment of prison violence risk among maximum security inmates was developed from a logistic regression analysis involving inmates serving parole-eligible terms of varying length (n = 1,503), life-without-parole inmates (n = 960), and death-sentenced inmates who were mainstreamed into the general prison population (n = 132). Records of institutional violent misconduct of these 2,595 inmates were retrospectively examined for an 11-year period (1991 to 2002). Predictors affecting the likelihood of such misconduct included age, type and length of sentence, education, prior prison terms, prior probated sentences, and years served. The scale was modestly successful, as demonstrated by an overall omnibus area under the curve of .719. Double cross-validation demonstrated minimal shrinkage. The authors have termed this experimental scale the Risk Assessment Scale for Prison.
