Cullen Poisons a Newly Transferred Patient with Digoxin at Saint Luke’s

The poisoning of a newly transferred patient at Saint Luke’s shows Charles Cullen using an ordinary nursing procedure to kill a woman already near death, then placing himself at the center of the attempt to save her. The episode turns on the gap between what the unit could see—a dying patient, a routine IV intervention, a code—and what its staff did not recognize: Cullen had introduced the lethal drug himself.

Transfer and the unit’s priorities

The patient was an elderly, gravely ill woman brought by ambulance from another facility. She had already suffered two cardiac arrests during the ride, and her death seemed imminent. On the unit, she was treated as a dump: a terminal patient transferred from elsewhere, in a practice that could help a hospital keep its mortality rate low. The distinction mattered to the staff at Saint Luke’s, proud of the hospital’s standing among the nation’s top hospitals; a patient likely to die threatened the numbers behind that reputation.

Cullen was called at home because a new transfer was coming in. He arrived after the woman had been settled in bed, where his male coworkers were complaining. He disapproved of their care, including putting diapers on patients rather than walking them to the toilet, and he generally preferred not to work with men. The staff’s attitude toward the new patient sharpened that contrast for him: he later recalled nurses laughing as though the woman’s arrival were a party.

Her doctor came to explain to the family why she had been transferred, what the ambulance trip and the repeated resuscitations had put her through, and what Saint Luke’s might do that the previous facility could not. Cullen knew this end-of-life conversation well. In his judgment, the answer to the family’s implicit question was that the hospital could do nothing more. The woman’s precarious condition made the case appear to belong to the familiar course of a terminal illness, even as it created the circumstances in which her death could be misread.

The injection and the code

Cullen chose what he thought of as the direct route: he injected digoxin into the piggyback port of the woman’s IV. The port was a normal access point for administering medication or flushing a line with saline. Digoxin was clear like saline, and the act could therefore resemble routine care if anyone entered the room. Saint Luke’s rooms were private, and one-on-one care was a selling point of the unit; no one came in while he injected the drug.

Afterward, Cullen put the vial and used needle into the sharps box and returned to the nurses’ station. He busied himself with the chairs and hovered nearby until the code began. Then he took charge, acting as code leader and trying valiantly to save the patient whose IV he had just poisoned. His visible role in the resuscitation did not expose the earlier injection; instead, the routine sequence of medication administration, waiting, and emergency response concealed it within the work of the unit.

The unit’s surrounding activity offered a grim counterpoint. Cullen remembered his coworkers playing Hacky Sack with a ball of tape. He understood gallows humor, but not treating the work as a game; they also played with nitroglycerin, smashing it outside against the parking lot to see whether it would explode. Their carelessness did not cause the poisoning, but it frames a workplace where dangerous materials and serious patient crises could sit beside casual behavior. When the woman finally died, her family gathered to mourn. Cullen had been her only assigned patient, and once the code was over he was permitted to leave.

A helpful appearance, a concealed route

The book places this direct injection beside Cullen’s later use of a more indirect method, while keeping the episodes distinct. On another shift, he arrived early, collected medicines delivered by a pharmacy runner, and took them into the medication supply room alone. He contaminated saline and switched the prepared bags, later helping colleagues start IVs and responding to a code. The actions could appear separately helpful, with no obvious reason for coworkers to connect them. That later episode makes the directness of the woman’s poisoning especially legible: Cullen could exploit either an ordinary IV access point or the less visible routines of stocking and preparing medication.

His habits also shaped where he could act. He preferred the hospital at night, when visitors, administrators, and other extras were gone, and the book describes him waiting through the quiet hours while monitoring patients. Amy Loughren later reconsidered his customary position at the end of the CCU’s L-shaped hallway, near the elevator doors and away from the nursing station. She realized that this was where he could be the first, and often the only, person to meet the pharmacy runner and take the delivery tote. What colleagues had read as helpfulness—saving the runner a trip and stocking the unit—could also give Cullen access to drugs without using the Pyxis system.

Death, suspicion, and the aftermath

The woman’s death was not presented to her family as the result of a proven crime. She had arrived critically ill, had already coded twice, and died after a code at Saint Luke’s; these facts made a natural explanation immediately available. The scene’s force comes from the knowledge withheld from those around her: Cullen’s injection preceded the emergency, and he then occupied the role of the nurse leading the effort to reverse it.

Later, Amy’s suspicions grew in the course of a broader investigation into Cullen. She had objected when her manager tried to make nurses sign an insulin adjustment form recording their estimates of how much insulin remained in a vial; the hospital did not tell her why the new accounting procedure had appeared. As rumors spread that Charlie’s name and insulin were connected with a death, coworkers began avoiding Amy, who was known as his friend. A detective later showed her a Pyxis printout from the night Reverend Gall died. The page made her consider that Cullen might have done something terrible, though she struggled to reconcile that possibility with the friend she believed she knew. These later events concern the investigation and other suspected patient harm, not evidence identifying the transferred woman; they show how a pattern of drug access and death gradually changed the meaning of Cullen’s apparently ordinary work.

Amy ultimately faced the risk of lying to Cullen and to her employer if she cooperated undercover. She continued helping investigators, sharing paperwork and pointing them toward Cerner patient records, while feeling exposed and alone in the institution she hoped to improve. The transferred woman’s case anticipates the central investigative difficulty: the same gestures that made Cullen look attentive—a routine injection, a prompt response to a code, help with supplies—could also conceal the act that caused the patient’s death.
