Amy Loughren Discovers Cullen Obtained Drugs from Pharmacy Runners
The Good Nurse: A True Story of Medicine, Madness, and MurderAmy Loughren’s discovery that Charles Cullen could obtain drugs by intercepting pharmacy deliveries changed the shape of the investigation: the missing Pyxis records no longer meant that his access to medication could not be traced. In a memory she recovered through self-hypnosis, Amy reinterpreted a familiar routine—Cullen waiting near the unit doors and taking a delivery tote from the pharmacy runner—as a way to bypass the dispensing system entirely.
The investigative dead end
The realization came against a practical obstacle. Investigators could not connect drugs to a particular nurse as they might trace a bullet to a gun; the access records they knew to look for were stored in Pyxis. Mary Lund had told them that the system retained drug data for only thirty days. Reverend Gall had been dead nearly four times that long, and the hospital had told investigators that the relevant records were gone. The case against Cullen appeared stuck, at least on the hospital’s account of what could be recovered.
The stakes of delay were already clear. At New Jersey Poison Control, Bruce Ruck reported his concern to director Steven Marcus, who believed that someone at Somerset Medical Center was killing patients and warned that waiting to acknowledge the evidence could put more patients at risk. Amy’s later insight did not itself establish what Cullen had taken or prove how he used it. It did, however, expose a gap in the investigators’ assumption: Pyxis could record medication removed from its machines, but it could not record medication obtained elsewhere.
Re-entering the memory
Before identifying that alternate route, Amy had a nightmare in which she was the patient: unable to move, with Cullen at the far end of the hallway. After waking, she recognized the location as his usual position, near the elevator doors and farther from the nursing station. The dream left her unsettled, but the discovery came through a deliberate return to her own memories. Amy used a self-hypnosis method she had practiced to confront painful childhood episodes, describing the process as reliving rather than simply remembering.
She placed herself back on shift with Cullen. After report, he would wheel the portable Cerner computer down the hall and work from a corner of the CCU. Amy had taken this as a preference for quiet. The scene’s apparent ordinariness had concealed its practical advantage: from that position, Cullen was close to the doors through which pharmacy deliveries arrived. Amy’s recollection turned a habitual workplace arrangement into a clue about access.
The pharmacy handoff
Cullen, Amy realized, was often the first person—and sometimes the only person—to see the pharmacy runner. He regularly met the runner and took the delivery tote of drugs, presenting the action as helpful: relieving the runner of the delivery and stocking the unit as part of his work. Amy had previously read the behavior as considerate busywork. In retrospect, the same routine gave Cullen an opportunity to obtain drugs without touching Pyxis.
That distinction mattered because the investigators’ apparent missing link was not necessarily missing in the way they thought. A Pyxis history could show activity within the dispensing system; it could not account for drugs brought onto the unit by a runner and handed to a nurse. Amy’s realization identified a possible route around the record trail, not a complete account of each drug’s destination or use. The insight was therefore both concrete and limited: it changed where investigators might look without, by itself, resolving the cases.
A routine recast as evidence
The episode gains force from the contrast between Cullen’s visible helpfulness and the concealed advantage it afforded him. The tote was not hidden in an isolated exchange; the handoff belonged to the ordinary flow of pharmacy work. Amy had seen the behavior repeatedly and had assigned it a benign explanation. Her recollection did not uncover a new action so much as reverse the meaning of one she already knew.
Other episodes in the book show why medication access could be difficult to interpret. At Saint Barnabas Hospital, a patient’s IV bag tested positive for insulin, and its exterior bore unusual needle marks; chart reviews found neither a prescription nor a nursing notation for insulin. Investigators compared patient-code schedules and identified Cullen as one of three nurses present at every code, though the evidence raised suspicion rather than demonstrating how the drug had reached the patients. At Saint Luke’s Hospital, Cullen entered a coded medication room alone after bringing pharmacy-delivered medicines there. These separate episodes show different points at which ordinary hospital procedures and drug access became investigative concerns; they do not establish that the same method was used in each place.
The recalled handoff adds a subtler mechanism to that pattern. Where a locked medication room, a marked IV bag, or a dispensing log could direct attention to a specific object or system, the pharmacy tote moved through routine work under the appearance of assistance. Amy’s discovery exposed how a familiar role could also create access—and why a search limited to Pyxis records might miss a route that left no Pyxis transaction.
