Nurse Accused of Killing 7 Babies Wrote 'I Killed Them on Purpose' in Note, Prosecutor Says

Lucy Letby, the 32-year-old nurse, allegedly killed seven infants in her care between 2015 and 2016 by injecting air into their bloodstreams. Her trial began last month.

According to BBC, Letby's supervisor testified on Monday that Letby was assigned to care for another premature baby. Still, she inexplicably showed up in the dead baby's intensive care unit several times the day he died. Prosecutors believe the cause of death of the premature baby was having air forced into his stomach via a nasogastric tube. 

While Letby denied the allegations, the prosecution has presented several handwritten notes in court, in which she allegedly wrote, "I killed them on purpose because I'm not good enough to care for them," the prosecutor said. In another, she allegedly wrote, "Not good enough. I will never have children or marry. I will never know what it's like to have a family."
