A two-hour gap between the time of Nicola Bulley's disappearance and the first call to police to report her missing is the latest line of enquiry being explored by investigators.
The mum-of-two was last seen with her dog Willow at 9.10am on January 27, not long after dropping off her children to school in St Michaels on Wyre, Lancashire.
Authorities have revealed that the first call relating to Nicola's disappearance came two hours later at 11am, The Mirror reports.
