Media reports say that she was recorded by a door bell camera as she passed by.
Just shows how modern day surveillance is much more that street cameras.
Just imagine how useful such technology might have been in PDL back in 2007 had it been around at the time.
That technology definitely gives evidence of Sarah's route and the time when she walked it ~ good on either an informed member of the public who knew what Sarah looked like and what she was wearing either because of police appeals or a police officer doing door to door enquiries as part of his job.
The police in PDL missed one of the few CCTV cameras which might have confirmed a witness sighting ~ and it appears that lack of official publicity may have distracted the witnesses who didn't realise they might have had valuable information until a fortnight after the event. the event.
Technology has progressed but that counts for nothing if it is ignored; it is available and hopefully on this occasion it will enable answers.
