Judicial Conclusion To A Fratricidal Tragedy

On May 1, 2026, the Old Bailey delivered a life sentence to 70-year-old Nancy Pexton for the murder of her sister, Jennifer Abbott, who was also known as Sarah Steinberg. Pexton, a resident of Gloucester Place in Westminster, was ordered to serve at least 22 years behind bars before becoming eligible for parole. The sentencing followed a jury's guilty verdict returned on April 29, concluding a case that shocked the Camden community. Judge Mark Lucraft, presiding over the trial, noted the "gravity" of the offense, which involved a calculated and violent breach of a familial bond. Detective Inspector Barry Hart described the outcome as a necessary reflection of the devastation Pexton inflicted through her refusal to take responsibility for the crime.

Discovery Of The Crime Scene In Mornington Place

The investigation began in June 2025 after a concerned family member visited Jennifer Abbott’s flat in Mornington Place, Camden, following several days of silence. Finding the door locked and receiving no response, the relative gained entry with the assistance of a neighbor. Inside the living room, they discovered Abbott lying on the floor with catastrophic stab wounds to her neck. Emergency services were summoned immediately, but paramedics from the London Ambulance Service pronounced the victim dead at the scene. Initial forensic assessments suggested the victim had been deceased for several days, prompting a wide-ranging inquiry into her final movements and personal associations.

CCTV Evidence And The Timeline Of Violence

Metropolitan Police detectives utilized extensive CCTV analysis to reconstruct the timeline of the murder, which they determined occurred on June 10, 2025. Footage showed Nancy Pexton traveling to her sister’s address on that Tuesday and leaving later the same day. Following Pexton’s departure, no further sightings or digital activity were recorded from Abbott, making the defendant the last known person to see her alive. Despite Pexton’s initial claims of innocence, the visual evidence established her presence at the scene during the exact window when the fatal injuries were inflicted. This temporal link became a cornerstone of the prosecution's case against the Westminster resident.
