British Aristocrat, Partner Jailed 14 Years for Newborn Daughter’s Manslaughter

British aristocrat Constance Marten and her boyfriend Mark Gordon have been sentenced to 14 years in prison for the gross negligence manslaughter of their newborn daughter, Victoria. The sentencing took place on Monday, September 15, 2025, at London’s Central Criminal Court, concluding a high-profile case that captured nationwide attention.
Marten, 38, and Gordon, 51, a convicted sex offender, were found guilty in July not only of manslaughter but also of perverting the course of justice, concealing the birth of a child, and child cruelty. Gordon received an additional four years on extended license. The judge ruled that baby Victoria died from hypothermia after being exposed to “significant cold stress,” rejecting the couple’s claims of a tragic accident.
The couple sparked a nationwide search after police discovered a placenta in their burned-out car in January 2023. They went off-grid, spending heavily on taxis and avoiding identification, eventually sleeping in a tent on the South Downs where their baby tragically died. Victoria’s decomposed body was later found in a shopping bag in a Brighton garden shed, concluding a seven-week search.
Detective Superintendent Lewis Basford expressed difficulty comprehending how the parents chose to live in freezing conditions to evade authorities, rather than providing care for their child. The tragic case highlighted Marten’s aristocratic background and Gordon’s history, as their other four children had previously been taken into care due to risk of harm.
