Between
February and April of 1991, Allitt went on a rampage. She was employed
as a State Enrolled Nurse at Grantham and Kesteven Hospital in the UK.
For no known reason at all, she successfully murdered four children,
attempted to murder three more, and caused serious bodily harm to six
more. She murdered the children by injecting them with lethal doses of
insulin, and also by injecting air bubbles into them.
