The Reta Mays VA Hospital Murders: The Unseen Monster Between July 2017 and June 2018, nursing assistant Reta Mays murdered seven elderly veterans and assaulted an eighth at a West Virginia VA hospital, injecting them with unauthorized insulin during her night shifts. For eleven months, the deaths went unrecognized as a pattern of serial homicide-attributed instead to natural causes as institutional failures enabled her crimes. This comprehensive investigation reveals how Mays operated: researching "female serial killers," watching documentaries about nurses who kill, and exploiting catastrophic security gaps including unsecured medications, incomplete background checks, and absent oversight. Through 300+ interviews, forensic exhumations, and digital evidence, federal investigators built an overwhelming case that ended with Mays receiving seven consecutive life sentences plus twenty years. But the story extends beyond one killer. It exposes the "serious, pervasive, and deep-rooted" institutional failures at the Louis A. Johnson VAMC, examines the pattern of healthcare serial homicides across decades, and documents the reforms-VHA Directive 1195, enhanced security protocols, and the SAFE Drugs Act-implemented to prevent future tragedies. Drawing from court documents, OIG reports, and investigative records, this book honors eight veterans whose deaths exposed vulnerabilities that threatened America's nine million VA patients and forced a reckoning with how institutions built on trust can become hunting grounds for predators.
