This may or may not already have been mentioned, but based on the Haworth Street footage and the time on the camera I have determined the following:
PR(?) unlocks his car and smokes a cigarette by it. He then leaves it again at 00:05:20 and walks towards Beverley Road where the bench is.
He returns with (possibly) LS at 00:06:54 - 94 seconds after he left.
Based on the average walking speed of an adult male, 1.4 m/s, it would have taken about 20 seconds to walk from the car to the bench where LS was last seen.
If we assume it took the same length of time to walk back to the car, we can work out that he would have been at the bench, with LS, for a maximum of 54 seconds.
Now is it possible to persuade a heavily drunk girl to get in a car with you in just 54 seconds? Possibly. Possibly not.
This is of course assuming that he definitely walked to the bench (we don't know that for sure), that he walks at average speed and that he didn't cross Beverley Road to the shops or walk further down the street.
I've been doing some measurements on Google Maps and have worked out the furthest possible distances he could have travelled on a number of different routes from his car.
Also does anyone know where this CCTV of LS actually on the bench is? I've heard loads about it but haven't actually been able to find it - maybe HumbPol haven't made it public? There are bus lane cameras down Beverley Road so it could be from them. If they have ANPR on them which they more than likely do they could be used to determine the owner of the suspect vehicle assuming it drove towards Oak Road Playing Fields.
Also from my own observations on StreetView of the bench area, there are no street lights on that side of the road and with the overhanging trees the area would likely have been very dark or poorly lit at the time, not to mention the weather at the time was cloudy/overcast and the moon was in a waning crescent phase.
