For this dataset I examined (n=27,151) published online open-source media reports of US transgender homicides alongside official data sources (i.e., government reports, police reports, post-mortem reports, prison records, etc.) over the course of several years. Official homicide victimisation data came from the FBI’s Supplementary Homicide Report (SHR), the most used official data source for homicide data in the US, alongside yearly Uniformed Crime Reports (UCR). Initial online open-media reports were identified through using LexisNexis and NewsBank databases while also searching for all news items published by online and print mainstream news outlets. Further relevant open-source material was initially identified by using a search string that contained the terms “homicide”, “murder”, “LGBT” and “transgender” alongside the state name/ jurisdiction where the reported homicide occurred. This included information on transgender and gender non-conforming victims from print, news magazines, news, alongside other open-source data from LGBTQ+ research agencies (e.g. Transgender Europe’s (TGEU) “Transgender Respect Versus Transgenderphobia Worldwide” Project and “Transgender Murder Monitoring Project”; Human Right’s Campaign’s (HRC) “Annual Reports of Anti-Transgender Violence” projects) and other advocacy information agencies (e.g. Transgender Center for Transgender Equality, GLAAD; Trans Lives Matter “Remember Our Dead Project”). This open-source information searching provided crucial missing details about the victims, the offenders, and case specific information not currently recorded in official FBI crime reports, local police reports, prison reports (if a homicide conviction), court reports (if a homicide sentence), or coroner reports where injuries and causes of death were outlined. Yet, relying solely upon non-profit or trans rights activists’ information regarding victimology and case specific details was limiting at times due to noticeable data inconsistencies. Therefore, I used official police, prison, court, and coroner reports to collaborate and cross-reference any case specific information form said non-profits.
