Nicola Bulley's Fitbit watch gave a heart rate output for eight days after she drowned, an inquest heard.
This week a coroner's court heard that the mum-of-two drowned in the River Wyre after she went missing on a dog walk on January 27. Nicola's body was found in the river about a mile from the bench, her mobile phone was found on, on February 19 after an extensive search.
When she was found, the Fitbit was still attached to her wrist and is believed to have lost power on February 4 as no further data had been obtained beyond that point and when it was placed on charge it displayed that date. The watch stopped recording steps beyond 9.30am on the day she disappeared, a digital specialist for Lancashire Police said.
