Hi Jessie, it seems I may have to agree with you. I did a bit of digging:
In relation to whether Libby’s phone was found inside or outside her home I have found an interesting article which would seem to indicate that it was found inside.
A Taxi Took Her Home And She Was Spotted On CCTV – So Where Is Libby Squire?
“Though police had at first suggested Squire did not enter her home after being dropped off, her mother Lisa reportedly clarified in a Facebook post that she had entered the property before subsequently vanishing.
She wrote: “She got out of the taxi at her house. She was home… simple.”
“Police revealed on Monday that they had found Squire’s mobile phone at her home, but that it had not helped to provide any information about where she went on Thursday night. Friends have said she didn’t have it with her during the day before she went missing.”
Thank you for your patience.

It's understood that having left the taxi at 11.29pm, Ms Squire did not enter the property.
Police later searched the house and found her mobile phone inside, but it did not offer up any clues as to where she might be.
