Beverley Gail Emma Louise Allitt (born 4 October 1968) is an English serial killer who was convicted of murdering four children, attempting to murder three other children, and causing grievous bodily harm to a further six children. The crimes were committed over a period of 59 days between February and April 1991 in the children's ward at Grantham and Kesteven Hospital, Lincolnshire, where Allitt was employed as a State Enrolled Nurse. She administered large doses of insulin to at least two victims and a large air bubble was found in the body of another, but police were unable to establish how all the attacks were carried out. In May 1993, at Nottingham Crown Court, she received 13 life sentences for the crimes. Mr. Justice Latham, sentencing, told Allitt that she was "a serious danger" to others and was unlikely ever to be considered safe enough to be released. She is detained at Rampton Secure Hospital in Nottinghamshire.
Allitt was born on 4 October 1968 and grew up in the village of Corby Glen, near the town of Grantham. She had two sisters and a brother. Her father, Richard, worked in an off-licence, and her mother as a school cleaner. Allitt attended Charles Read Secondary Modern School, having failed the test to enter Kesteven and Grantham Girls' School. She would often volunteer for baby-sitting jobs and left school at the age of 16, taking a course in nursing at Grantham College.
Allitt had attacked thirteen children, four fatally, over a 59-day period before she was brought up on charges for her crimes. It was only following the death of Claire Peck that medical staff became suspicious of the number of cardiac arrests on the children's ward and police were called in. It was found that Allitt was the only nurse on duty for all the attacks on the children and she also had access to the drugs.
