The Mary Bell case is the 1968 prosecution of an eleven-year-old girl from the Scotswood district of Newcastle upon Tyne who strangled two preschool-age boys, four-year-old Martin Brown and three-year-old Brian Howe, within roughly two months of each other. Mary Flora Bell was convicted of manslaughter on the grounds of diminished responsibility, sentenced to indefinite detention, released on license in 1980 after twelve years, and now lives under a permanent High Court injunction that protects her identity for life.
Who Mary Bell Was
Mary was born on 26 May 1957 to Elizabeth “Betty” McCrickett, a teenager who reportedly rejected her from birth. According to accounts later gathered by journalist Gitta Sereny, Betty shouted at hospital staff to take the baby away immediately after giving birth. Betty worked as a prostitute and was frequently absent, traveling to Glasgow and leaving her children behind. The man Mary believed to be her father, Billy Bell, was a violent alcoholic with a criminal record that included armed robbery.
Family members later told Sereny that Betty made repeated attempts to harm Mary during her early childhood, disguising the incidents as accidents. In one instance, Betty reportedly dropped Mary from a first-floor window. In another, she allegedly gave the child sleeping pills. There are also accounts that Betty forced her young daughter to participate in sexual acts with clients. Psychiatrists who later evaluated Mary noted that the abuse she witnessed and endured likely damaged her psychological development in ways that shaped what followed. This history sat at the center of every legal and clinical assessment of her case, though at the time of the trial no relatives came forward to describe it.
The Deaths of Martin Brown and Brian Howe
On 25 May 1968, four-year-old Martin Brown was found dead inside a derelict house on St. Margaret’s Road in Scotswood. There were no obvious signs of violence, and a bottle of aspirin found nearby led investigators to treat the death as accidental. Two days later, a nearby nursery school on Woodlands Crescent was broken into and ransacked. Four handwritten notes were left behind claiming responsibility for Martin’s death. One read, in part, “we did murder Martain Brown.” Police did not treat the notes as a credible threat at the time.
On 31 July 1968, three-year-old Brian Howe was found on a patch of wasteland known locally as the Tin Lizzie. He had been strangled. His legs bore puncture wounds, his hair had been hacked with scissors, and the letter “M” had been scratched into his torso with a razor blade. A broken pair of scissors and the blade were found near the body. The deliberate violence made an accidental explanation impossible, and Martin Brown’s death was reopened in that light.
How Police Identified Mary Bell
Investigators conducted door-to-door interviews with more than a thousand local children. Two girls stood out: eleven-year-old Mary Bell and her thirteen-year-old friend Norma Bell, no relation, who lived next door to each other on Whitehouse Road within walking distance of both scenes.
Mary’s behavior during questioning drew immediate suspicion. She volunteered details about the killings that had not been made public, showed an odd excitement when discussing the deaths, and gave contradictory accounts that seemed designed to test what police already knew. Other children reported seeing the two girls near the derelict house and the wasteland around the relevant times. That combination gave police enough to arrest both.
The Trial and the Manslaughter Verdict
The trial opened at the Newcastle Assizes in December 1968. Both girls were charged with two counts of murder. Norma was acquitted; the jury regarded her as a passive figure who had been led by her younger companion. Mary was found not guilty of murder but convicted of manslaughter on the grounds of diminished responsibility.
Under the Homicide Act 1957, a defendant whose mental functioning is substantially impaired by a recognized medical condition at the time of the killing can be convicted of manslaughter rather than murder, provided the impairment explains the defendant’s actions.1Legislation.gov.uk. Homicide Act 1957, Section 2 In Mary’s case, psychiatric evaluation found traits consistent with a psychopathic personality disorder. The defense leaned on those clinical findings because no family members came forward to describe the abuse in her home.
Detention “at Her Majesty’s Pleasure”
The judge sentenced Mary to detention at Her Majesty’s pleasure, the mandatory sentence for anyone convicted of a killing who was under eighteen at the time of the offense. This is an indeterminate sentence with no fixed end date. Under the governing statute, the Secretary of State decides when and whether the detainee is released, weighing punishment, public safety, and the welfare of the child.2Legislation.gov.uk. Powers of Criminal Courts (Sentencing) Act 2000 – Detention at Her Majestys Pleasure or for Specified Period As the House of Lords later explained in a related case, the sentence is “wholly indeterminate in duration” and reflects a legislative intent to take a flexible approach to child offenders that goes beyond adult sentencing frameworks.3Parliament of the United Kingdom.

Mary spent twelve years in various institutions, including a period at Red Bank Special Unit, where she was reportedly the only female offender. She was gradually moved to less restrictive facilities as she grew older.
Release, New Identity, and the Sereny Book
Mary Bell was released on license in 1980 at the age of twenty-three. She was given a new identity and tried to build a private life. In 1984 she gave birth to a daughter. A tabloid discovered the birth, and the exposure forced her to relocate. That pattern repeated over the years: journalists tracked her down, and she moved to escape the spotlight. The license conditions meant she remained subject to recall, but the practical pressure on her stability came from the press rather than the state.
In 1998, journalist Gitta Sereny published Cries Unheard: Why Children Kill — The Story of Mary Bell, a biography based on extensive interviews. The book offered the most detailed account of Bell’s abusive childhood and her own perspective on the killings. It also revealed that Sereny had paid Bell for her participation. Reports placed the figure at around £50,000, though the exact amount was never officially confirmed. The revelation caused public outrage. Sereny defended the payments, saying she had given Bell the money to prevent her being further exploited. The controversy fed broader legislative discussion of profit from the commercial exploitation of crime, and the Coroners and Justice Act 2009 later included provisions addressing such payments.4Legislation.gov.uk.

The Mary Bell Order
In May 2003, Dame Elizabeth Butler-Sloss, then president of the Family Division of the High Court, granted a permanent injunction protecting the identities and whereabouts of Mary Bell and her daughter. It became known as the Mary Bell Order and was only the second time a British court had granted lifelong anonymity of this kind. The injunction prohibits publication of any information likely to identify Bell as the woman formerly known by that name, or to identify her daughter as Bell’s child. It covers names, locations, images, physical descriptions, and voice recordings.5vLex United Kingdom. X (A Woman Formerly Known as Mary Bell) and Another v OBrien and Others
The reasoning balanced competing rights under the European Convention on Human Rights, as incorporated into UK law by the Human Rights Act 1998. Bell and her daughter’s right to private and family life under Article 8 was weighed against the public’s right to freedom of expression under Article 10. The court found that Bell’s fragile mental state, the exceptional circumstances of her case, and the age at which she committed the crimes justified restricting press freedom to protect her privacy.6Press Gazette.

Violating the order is treated as contempt of court, punishable in the UK by up to two years in prison, a fine, or both.7GOV.UK. Contempt of Court The order has since served as a legal reference point for subsequent anonymity injunctions involving other former child offenders, most notably the killers of James Bulger. It remains one of the most significant privacy rulings in British law, and the tension it embodies between public accountability and the possibility of rehabilitation has never fully resolved.
