What Motivates Killer Nurses?

British neonatal nurse Lucy Letby was recently convicted of murdering seven babies, in a years-long case that has horrified the United Kingdom. But serial-killer nurses, it turns out, are more common than many would like to believe.

LONDON – Recently convicted of murdering seven babies and attempting to kill six others at the Countess of Chester Hospital between June 2015 and June 2016, neonatal nurse Lucy Letby has the grisly distinction of being the United Kingdom’s most prolific child serial killer. Over the course of Letby’s ten-month trial, believed to be the longest murder trial in UK history, prosecutors detailed how she had harmed the infants in her care by injecting air and insulin into their bloodstreams, infusing air into their abdomens, and dislodging their breathing tubes.
