Almore, a registered nurse employed at Britthaven of Chapel Hill in North Carolina, reportedly gave a dose of unprescribed morphine to 84 year-old Rachel Holliday, an Alzheimer’s resident who later died. The medical examiner attributed Holliday’s death to pneumonia from asphyxiation and reported that this nursing home medication error and the levels of morphine in her system likely contributed to her death.

Almore was also charged with six counts of felony patient abuse after other Britthaven reportedly became lethargic and had to be hospitalized. Testing revealed that all of the affected residents had morphine in their systems, although none of them had been prescribed the drug.

The investigation continues.
