QUOTE="Armchair_Defective, post: 14793166, member: 211947"]I had wondered if police got the precise timings from the driver, as in 'she was in that area up until 12.09'. either the driver drove back that way at 12.09 and had dashcam footage of her no longer on the bench...or they said they drove back that way and saw her gone and had an alibi ( such as a receipt from a shop etc) at 12.09.
I think they will have gone with the driver's version of events until they had good reason not to. In so many cases, such as missing children they can only go on the version of events given unless evidence comes to light that disproves that. They are not going to declare someone a suspect or non-suspect outright at the start of an investigation.
As for the 24 year old arrested, it's a student area and he is quite young so maybe a fellow student? He could have had an older accomplice, or maybe he had white blonde hair that accounted for the 'grey' description. It's so common for sex offenders to look out for drunk or vulnerable women on their own, even come back and carry out a crime after they've planned what to do.
There could also be a personal angle, someone known to Libby and they had a disagreement not many of her friends knew about.[/QUOTE]
I have 2 male pals who both turned completely grey in their early 20s - I know it's unusual, but it is possible.
