In 1992, relatively stable patients at the VA hospital in Columbia, Missouri were dying on one ward’s overnight shift at an alarming rate. A review of the charts showed nurse Richard Williams had been present for most of the Code Blues, but he denied being responsible for the deaths. Whistleblowers accused VA administrators of keeping the situation quiet and retaliating against staff who tried to stop it. Even the FBI seemed to slow-walk the investigation, leaving grieving families to wonder whether anyone will be held accountable for the deaths of up to 50 ill veterans.

In the latest installment of the podcast from Sony Music Entertainment and Campside Media, “Witnessed: Night Shift” reinvestigates the Columbia VA deaths. Who did it? Why did the hospital try to cover them up? Author Jake Adelstein interviews doctors - including his own father - who fought the government to identify one of the most prolific serial killers to roam a hospital.
