Anne Potter's remains have been on a beach in Brighton, following her disappearance in autumn 2024.
Mrs Potter was last seen leaving her home in St Lawrence at around 12:30 pm in October 2024.
It was believed she was heading towards Greve de Lecq.
Emergency services carried out an 'expansive' search on the North Coast, between L'Etacq and Sorel Point, with the Coastguard, the RNLI and the Jersey Lifeboat Association searching the coastline.
However, DCI Mark Hafey, who led the investigation, revealed the police have confirmed the death of Anne Potter.
"Remains were located on a beach in Brighton, which have now been confirmed as a DNA match with Anne."
"Anne was reported missing to SOJP, prompting an immediate multi-agency response.
"Despite extensive search efforts, Anne was not located.
"Our thoughts are with her husband, family, and friends."
The coroner is considering the circumstances of the death and whether any further investigation is required in consultation with the coroner in Sussex, where Mrs Potter was found.
