This study examines the effects of adverse childhood experiences (ACEs) on the risk of internalizing or externalizing outcomes among juveniles. While myriad research has investigated the impacts of ACEs on internalizing and externalizing outcomes, it is unclear whether ACEs have a stronger link to one outcome over the other when controlling for other factors. Using a sample of 30,909 youth who exclusively exhibited internalizing ( n = 1,030) or externalizing problems ( n = 29,879), regression techniques and propensity score matching were utilized to evaluate the impact of each ACE on the risk of internalizing versus externalizing outcomes. Results indicate that the most pertinent factor for predicting externalized problems is emotional abuse. Household member incarceration, physical abuse, emotional neglect, and household violence or substance abuse also predicted externalizing outcomes. Sexual abuse was the only ACE predictive of internalizing, while physical neglect and parental mental illness did not have a correlation with either outcome.

Purpose The purpose of this study is to outline the specific details and lessons learned during a cold case collaborative effort, which granted graduate students and a professor from the University of South Florida the opportunity to assist Pasco Sheriff’s Office in the investigation of a cold case homicide. Methodology The collaboration between law enforcement and academics is a new and emerging strategy to investigate cold cases and identify the elusive offenders who committed these crimes. Such collaboration aids law enforcement by obtaining a force multiplier for investigative resources, accessing cutting-edge evidence-based research and cultivating innovative approaches to their work. For academics, such collaboration allows the unique opportunity to engage in translational criminology, which is an important and increasingly encouraged aspect of the field. Findings In this paper, the authors provide an overview of the process used to study this cold case as part of an experiential academic course, provide evidence-based research findings relevant to cold case investigations and outline the steps for others to replicate the efforts. Originality/value The authors describe in detail the process used to “work” the cold case, academic research that the authors found useful in understanding and investigating cold cases, important lessons learned and advice for future academics and practitioners who undertake an incredible collaborative effort such as this.

The unique feature of social media as a platform for news is that the public can directly engage with content. In this way, the public shapes the narrative on current issues, including crime. Criminal justice agencies have leveraged this engagement to relay information about missing persons’ cases quickly and efficiently to a large audience. Whereas previous research has explored disparities in news coverage of missing persons’ cases, it is unknown whether the public perpetuates these same disparities in the social media realm. This study contributes to the current literature by examining public engagement with missing persons’ social media content. Results suggest that engagement along some dimensions corresponds to disparities found in traditional news coverage, namely with regard to race, where marginalized victims experience less engagement. Further, there is evidence of an interaction between race and runaway status. Certain posting behaviors are also related to several forms of user engagement with missing persons’ posts; however, case characteristics remain prominent engagement-shaping factors. Implications for these findings are discussed from both a theoretical and practitioner standpoint.
