Ok so if I'm reading this correctly all the info. is being relayed by an anonymous friend (maybe TA) so maybe take it with a pinch of salt especially as the part about Paul not ringing the police until he got there is incorrect....
The friend, who wishes to stay anonymous, told the Mirror she has spoken to a pair who believe they were the last people to see Nicola before she went missing.
She said: "They say she was laughing and joking with them as she went by."
She went on to say two other dog walkers later came across her phone and recognised the screensaver photo.
She said they were unable to unlock the phone and contacted a friend who then called St Michael's-on-Wyre Church of England Primary School, where Nicola had dropped her two children earlier that morning.
Partner Paul Ansell was contacted and raced to the scene from the family home three miles away in Inskip, before calling the police, the friend said.
"As far as I’m aware, no one called the police until Paul arrived," she said.
