Mary Bell is an English woman who, as a child aged 10-11 in 1968, strangled to death two toddlers in Scotswood, an inner-city suburb in the West End district of Newcastle upon Tyne. She was convicted in December 1968 of the manslaughter of Martin Brown (aged 4) and Brian Howe (aged 3). Since her release from prison in 1980, she has lived under a series of pseudonyms. Her identity has been protected by a court order, which has also been extended to protect the identity of her daughter. In 1998, Bell collaborated with Gitta Sereny on an account of her life, in which she details the abuse she suffered as a child at the hands of her mother - a prostitute - and her mother's clients.
In 1980, Bell, aged 23, was released from Askham Grange open prison after having served 12 years and was granted anonymity (including a new name), allowing her to start a new life. Four years later she had a daughter, born on 25 May 1984. Bell's daughter did not know of her mother's past until Bell's location was discovered by reporters in 1998 and she and her mother had to leave their house with bed sheets over their heads.
