Kristen Gilbert: The VAMC Nurse Who Killed Four Patients

The murders committed by Kristen Gilbert took place between 1988 and 1996 at the Veterans Affairs Medical Center (VAMC) in Northampton, Massachusetts, where the nurse injected lethal doses of epinephrine into patients' IV bags. Kristen Heather Gilbert was convicted in March 2001 of killing four hospitalised veterans in one of the most shocking series of murders in American hospital history.

Gilbert was on duty during more than 100 deaths in her ward. Colleagues began to notice the unusual pattern and gave her the nickname "Angel of Death" because of the rising number of deaths during her shifts.

The method was lethal. Gilbert injected lethal doses of epinephrine — a cardiac stimulant — directly into patients' intravenous therapy bags. This induced cardiac arrest in the innocent patients admitted to the hospital.

The confirmed victims were all veterans: Stanley Jagodowski, Henry Hudon, Kenneth Cutting and Edward Skwira. Each of them was a patient during Gilbert's shifts when they died.

In 1996, three nurses reported their concerns about Gilbert's behaviour to management. That became the starting point for an investigation intended to uncover the truth behind the unusually high death toll.

Staff speculated that Gilbert might be responsible for 350 or more deaths. That figure was never legally confirmed, but it illustrates the scale of what the investigation uncovered.

Gilbert was charged with four counts of murder, two counts of attempted murder and a bomb threat. In September 1996 she called the hospital and threatened to plant a bomb — an act investigators interpret as retaliation for the ongoing inquiry.

She was first convicted of the bomb threat in April 1998. That was only the beginning of a longer legal process.

The verdict came in March 2001, after a trial that began in October 2000. The court found Gilbert guilty of three counts of first-degree murder, one count of second-degree murder and two counts of attempted murder.

The Kristen Gilbert case raises fundamental criticism of hospitals' safety procedures and supervision of staff. How could so many deaths go unnoticed? What should have been done earlier? These questions have shaped the debate since Gilbert's conviction.

Gilbert's case has become a classic example of an "angel of death" serial killer — a professional healthcare worker who exploits their position to take lives. It underlines the importance of taking colleagues' concerns seriously and implementing stricter controls on medication handling in hospitals.
