Coincidence or homicide? That was the question circulating the halls of the Truman Memorial Veterans’ Affairs Hospital, in Columbia, Missouri, back in the summer of 1992, when an alarming number of patients began unexpectedly dying. Early investigation by the hospital’s epidemiologist found that nearly all of these deaths occurred during the night shifts of a male nurse, Richard A. Williams. As more employees began making the haunting connection, they soon found themselves not only indicting Williams but also fighting off the hospital’s administration, which preferred the murders swept under the rug. Missouri journalist Jake Adelstein and co-host Shoko Plambeck dive deep into the serial-killer case in Witnessed: Night Shift—the sort of true-crime podcast that you wish weren’t true to begin with. —Jack Sullivan
