While a large body of empirical research indicates that marriage is associated with criminal activity, to date little research exists on the effects of relationship status on a population of offenders returning to their communities. This study uses data on over 650 former prisoners to examine the impact of relationships on recidivism, substance use, and employment during this critical period of re-entry. Findings suggest that marriage cut the odds of recidivism and drug use in half when compared to those in casual relationships.

The Ohio Department of Rehabilitation and Correction and the Corporation for Supportive Housing Ohio Office developed a pilot program that provides permanent supportive housing to individuals released from several Ohio prisons. The Pilot intends to reduce recidivism and homelessness/shelter usage and decrease the costs associated with multiple service system use. The Urban Institute is evaluating the Pilot to explore whether it is meeting its intended goals. This Interim Report covers the first year of the evaluation—describing the Pilot and its eligibility requirements; the UI evaluation methods; and the characteristics and preliminary outcomes of the Pilot's first 57 clients.

A National Academy of Sciences report addresses the science-or lack thereof-in America's crime labs and criminal justice system. John Roman explains why a new era of scientific policing may be at hand.

The primary goal of this research is to estimate the costs and benefits of serving misdemeanor DUI offenders in the Anchorage Wellness Court (AWC), a specialized court employing principles of therapeutic jurisprudence. The Urban Institute conducted an impact and a cost-benefit analysis (CBA) to estimate the effectiveness of the AWC. The study focused on the impact of the program on reducing the prevalence and incidence of new criminal justice system contact. Costs were collected to estimate the opportunity cost of the AWC. Recidivism variables were monetized to estimate the benefits from crime reductions. Outcomes were observed at 24, 30, 36, and 48 months.

The study compared traditional crime solving to biological evidence techniques in hundreds of cases where biological evidence was available. When conventional investigative techniques were used, a suspect was identified 12 percent of the time, compared to 31 percent of the cases using DNA evidence. In eight percent of cases built on traditional evidence alone a suspect was arrested, compared to the 16 percent arrest rate in DNA cases. The average added cost for processing a single case with DNA evidence was about $1,397. Each additional arrest-an arrest that would not have occurred without DNA processing-cost $14,169.

Overcrowded jails and more spending for incarceration aren't predestined. In a Philadelphia Daily News commentary, two Urban Institute researchers explain how programs to help repeat offenders return successfully to society can cut crime and save money.

Despite a growing consensus among scholars that substance abuse treatment is effective in reducing recidivism, strict eligibility rules have limited the impact of current models of therapeutic jurisprudence on public safety. This research effort was aimed at providing policy makers some guidance on whether expanding this model to more drug-involved offenders is cost-beneficial. We find that roughly 1.5 million arrestees who are probably guilty (the population most likely to participate in court monitored substance abuse treatment) are currently at risk of drug dependence or abuse and that several million crimes could be averted if current eligibility limitations were suspended and all at-risk arrestees were treated.

This study assesses the death penalty's costs to Maryland taxpayers by examining a sample of the 1,136 death-eligible murder cases occurring between 1978 and 1999. We find that an average capital-eligible case in which prosecutors did not seek the death penalty will cost approximately $1.1 million over the lifetime of the case. A capital-eligible case in which prosecutors unsuccessfully sought the death penalty will cost $1.8 million and a capital-eligible case resulting in a death sentence will cost approximately $3 million. In total, we forecast that the lifetime costs to Maryland taxpayers of these capitally-prosecuted cases will be $186 million.

In this Washington Examiner commentary, John Roman explains why automatically putting juvenile offenders in adult detention is a mistake: it can turn the teenagers into hardened criminals and sends the message that society has written them off.

John Roman, a senior research associate in UI's Justice Policy Center, focuses on evaluating innovative criminal justice policies and programs. He discusses the rise in violent crime, effective prevention strategies, and what the candidates need to know about justice policy.
