Felix Kirk McDermott was an 82-year-old retired U.S. Army sergeant and Vietnam veteran who died on April 9, 2018, at the Louis A. Johnson Veterans Affairs Medical Center in Clarksburg, West Virginia. He’d been admitted on April 6 for shortness of breath and suspected aspiration pneumonia and initially seemed to be improving.

In the early hours of April 9 he developed sudden severe shortness of breath, restlessness and pain; a finger-stick test showed his blood sugar had fallen to an extraordinarily dangerous level. McDermott was not diabetic and had no physician’s order for insulin during that hospitalization, yet later examination after exhumation found evidence he had been given insulin by injection. The Armed Forces Medical Examiner classified his death as a homicide amid a broader investigation into unexplained hypoglycemic episodes among veterans at the same VA hospital. Investigators identified a former night-shift nursing assistant as a person of interest and linked similar insulin injections to other patients; federal charges were later brought in connection with several deaths.

McDermott at the VA or notice anything unusual on that ward in April 2018?
