Lucy Letby prided herself on caring for infants. 

The neonatal nurse cared for the most vulnerable of patients: newborns. Then, the hospital noticed that more infants died in the span of a month than would typically die in a year. An investigation reveals that Letby had been the sole nurse working at the time of seven babies. 

The child deaths span over the course of a year with, again, seven babies dying, while six others survived. Letby made babies sick by injecting intravenous lines with air, some were poisoned, and others were force-fed milk.     

Letby preyed on twins and triplets. Now, a major new documentary has been released on Netflix,  titled The Investigation of Lucy Letby.
