Mary Flora Bell was convicted in December 1968 of the manslaughter of two boys, Martin Brown (aged four years) and Brian Howe (aged three years). Bell was ten years old when she killed Brown, and eleven when she killed Howe. After serving 12 years, she was released, given Anonymity, and allowed to live the rest of her life
On 25 May 1968, the day before her 11th birthday, Mary Bell strangled four-year-old Martin Brown. They believed she committed this crime alone. On 31 July 1968, three-year-old Brian Howe, was killed in the same Scotswood area. Police concluded that Mary Bell had carved an "N" on his stomach with a razor; she later came back and made it an "M", she cut some of hair, scratch his legs, and mutilate his penis. She walks free today.
