A judge on Monday handed 14-year prison terms to aristocrat Constance Marten, 38, and her partner Mark Gordon, 51, after finding the pair guilty of causing the death of their newborn daughter Victoria by gross negligence. The couple were also convicted of child cruelty, concealing the birth of a child and perverting the course of justice.
Judge Mark Lucraft told the defendants they had acted with "arrogance" and a disregard for their child’s welfare, saying their conduct amounted to "neglect of the gravest and most serious type" that led to Victoria’s death from hypothermia. The court heard the couple fled to avoid the newborn being taken into care and spent nearly two months travelling around the country before camping in a flimsy tent on the South Downs in winter.
Prosecutors said the case began to unravel on Jan. 5, 2023, when a placenta was discovered after a car explosion on a Manchester motorway, triggering a nationwide manhunt. Scotland Yard led an extensive search that involved more than 100 officers and has been estimated to have cost more than £1.2 million. Five police forces ultimately joined the investigation, which prosecutors said consumed around 1,000 officer hours. The wider inquiry and trial have cost taxpayers about £2.8 million, the court was told.
The court heard that the couple travelled by taxi from Bolton to Liverpool, then to Harwich in Essex and east London before camping on the South Downs. Victoria died in their tent in freezing conditions. After her death, prosecutors said, the parents wrapped the infant in a soiled nappy, placed her in a Lidl "bag for life" and hid the body in a disused shed beneath discarded packaging and an empty beer can. The couple were arrested near Brighton after nearly two months on the run.
In passing sentence, Judge Lucraft said the defendants had the financial means and opportunity to care for their child but had chosen not to do so, adding that over the course of the trial they had sought to place blame on others. He ordered that both serve 14 years behind bars. The judge directed that Marten will serve two-thirds of her sentence before becoming eligible for release on licence; he imposed an extended custodial element on Gordon and ordered an additional four years on licence on his release after deeming him a danger to the public.
The convictions followed a trial that lasted two years. Jurors found the couple guilty of manslaughter by gross negligence, a verdict that reflected the prosecution's case that their decision to flee and to live in inadequate shelter in winter directly caused Victoria's death.
Defense lawyers argued for mitigation. Thomas Godfrey, representing Marten, told the court she was suffering from a depressive mental disorder at the time of the baby’s death and said the sorrow she felt was "incalculable". Philippa McAtasney KC, acting for Gordon, said he regretted making "bad decisions." Observers in the packed courtroom noted Marten sighed when the judge explained she would serve two-thirds of her term; Gordon showed no visible emotion as the extended element of his sentence was announced.
The sentencing hearing also included references to the defendants' backgrounds. Marten is an heiress from a wealthy family; the court heard her father served as a page to the late monarch and that members of her family moved in aristocratic circles. A probation report read to the court said Marten told an officer she expected to regain access to a family trust fund at age 40 and would be able to withdraw cash from another fund on release.
The court heard material about Gordon’s past convictions. Records presented during the proceedings indicated he had previously been sentenced in the United States as a juvenile to a lengthy term for a sexual offence, a history the judge referenced in deciding an extended sentence element was necessary.
Marten’s mother, Virginie de Selliers, made a plea for clemency in a character reference read to the court on her daughter’s behalf, describing Constance as "feisty" and praising her determination in fighting for her children. In the statement she urged that Marten’s courage and loyalty be taken into account when considering her future. A friend of Marten’s father told the court the father had expected a sentence of the scale imposed and said he believed his daughter had not shown remorse.
The prosecution described the couple’s flight and concealment of the birth as a deliberate attempt to frustrate social services and the authorities. Counsel for the Crown argued their actions were driven by a fear that the newborn would be taken into care, but that flight had exposed the infant to lethal conditions.
Sentencing concluded a case that has drawn sustained public attention because of the couple’s social background, the scale of the police operation and the circumstances of the infant’s death. The sentences will be subject to the normal appeals process, and probation and prison services will manage the defendants’ terms and any conditions on future release.
Court officials said arrangements will be made to ensure the authorities fulfil safeguarding obligations relating to the family's remaining children and to review any outstanding investigative matters arising from the case.
