Nicola Bulley's Fitbit gave a heart rate output for eight days after she drowned, an inquest heard. The mum-of-two drowned after entering the cold river water - and there is no evidence anyone else was involved in her death, the coroner's court was told on the first day of an inquest on Monday.
The 45-year-old went missing after dropping her daughters at school and going on a dog walk on January 27 along the River Wyre in St Michael's, Lancashire. Her phone - still connected to a work call - was found on a bench overlooking the water, while pet Willow was wandering nearby.
Nicola's body was found in the river about a mile from the bench on February 19 after an extensive search.
