"the last confirmed sighting and at 9:20, when Nicola's phone was found on the bench... sorry, not found on the bench, Nicola's phone was on the bench believed to be on the bench found at around 9:33"
From the transcript:
Reporter - How was the phone known to be on the bench at 9:20 exactly?
Superintendent - Through telephony enquiries that we've done, relative to the phone itself, rather than through a witness.
Reporter - So it wasn't (inaudible)?
Superintendent - No.
They don't ever say it was definitely found ON the bench.
