This report summarizes the Urban Institute’s evaluation of training and technical assistance (TTA) provided by the National Center for Victims of Crime (NCVC) in support of Multidisciplinary Responses to Families and Communities in Complex Homicide Cases, a multisite demonstration funded by the Office for Victims of Crime (OVC). The Complex Homicide project aimed to enhance multidisciplinary responses to homicide that were victim-centered, trauma-informed, and effective in addressing the needs of families and communities after the most complex homicide cases. Urban’s researchers reviewed Complex Homicide documents and spoke with leaders and staff from the seven demonstration sites. Overall, this evaluation indicated that NCVC met its core TTA objectives, though some opportunities for improvement were noted. According to sites’ feedback, NCVC offered responsive assistance and diverse subject matter expertise, assessed and supported most TTA needs, coordinated trainings on trauma-informed care and evidenced-based practices, and identified expert consultants to provide support that was, for the most part, tailored to sites’ needs. Nearly all sites suggested that opportunities for peer-to-peer connections be expanded in future efforts. As this evaluation was conducted post hoc, these findings are limited in that they represent information gathered retrospectively, although Urban’s team summarized that information as accurately and fairly as feasible.
