All very good questions I must say and the answers are in the statement by the police that they searched over 1000 vehicles and obviously spoke to the drivers too.And these would include the vehicles you are talking about .
The police would have ascertained which morning/afternoon Claudia walked and which morning /afternoon she got a lift and by whom ,
As I understood it from the Missing or Murdered programme in the first 2 months over 1000 witness statements had been taken and 240 properties were searched all of which drew a blank. By all accounts this was a huge task for the 100 officers assigned to the case.
I would be interested to know where it was reported that the police had searched a 1000 vehicles?
What have the police got to loose by disclosing details of how she travelled to work in the days prior to her disappearance?
Could that cctv footage provide evidence or prompt someones memory of a person seeing a male watching,in a vehicle or on foot following CL on her route to work on the days prior to her disappearing. As it is we have nothing so you arent going to get anyone coming forward to say I know him I know that vehicle hes always around watching girls as they are walking to and from college! These type of men get off watching and following woman/young girls and colleges provide a perfect opportunity for such an activity, they start with watching then photographing and then assualt/absconding them.
Anyone who passed melrosegate PO cctv at the times when CL was on her usual walk route to and from work could have valuable information.
Its possible that nothing or no one in CL's life prior to the 19th had anything to do with her disappearance and its quite possible that a complete stranger could have been the person responsible for her disappearance so its extremely important to have as much details out there as possible.
Where we hope the police have done a thorough investigation we have found their investigation lacking.
They highlighted the fact that CL had left the house on the 18th for 15 minutes but they have never found out where she went .. I ask you how far can a women get (7.5 mins out and thats if she turns right around and comes back) Theres a cctv camera at the Limes which would clearly show if she went in that direction and a cctv at costcutter if she got that far, a woman witness even said she saw her on her return journey so they have some idea which direction she had come from and still they didnt find out where she went.Duh!
