Much speculation has been made in the media as to the causes of mass murder in the United States, yet little empirical research exists to verify factors leading to violence. Prior research primarily relies on case study methodologies or small data sets, but none have focused on the underlying issues observed in a comprehensive national sample. Data for the current study include 152 mass murders reported through the FBI's Supplementary Homicide Reports and USA Today from 2007 to 2011, which were then matched with media reports for each event. The current study shows that mass murders typically occur following a triggering event, are committed by non-strangers, and are rarely committed by persons with mental illnesses. A more realistic image of these incidents is critical, as misperceptions of offenders and case characteristics can improperly shape public policies.

Juveniles who are transferred to adult court are more likely to recidivate than non-transferred juveniles, but limited research has examined how transfer can impact other life outcomes like attending college and employment. To examine this issue, data from the National Longitudinal Survey of Youth (1997) were analyzed from 1998 to 2011. It was found that court involvement during adolescence does not harm educational attainment. However, prosecution of juveniles in adult court significantly impairs earning potential well into adulthood. The current study provides further evidence of the long-term harms caused by transfer and demonstrates how transfer further disrupts the desistance process.

Cybercrime has become a growing national and international concern because of its potential for widespread and devastating financial impact. Gauging the effect of cybercrimes is extremely difficult because of its multi-faceted nature and evolving definitions, especially in cross-culture analyses. Using data generated from cybercrime reports from two leading national newspapers during the past ten years, this study compares major cybercrimes and law enforcement in China and the United States. Similarities and differences between the two nations are highlighted and policy implications are presented based on these findings.
