Hello
@An_Owl and thanks for your detailed post.
Police admitted early on in the case that there were problems in 2009 with the timings of the early morning cctv footage of Heworth Place/Limes Court. It may be possible to uncover the outcome of this by digging back through news reports from March to June 2009. Then, of course, the theory emerged that the man featured in the clip was the (by then deceased) local landlord Mr. Cartwright. After the furore raised by his family about linking him to the disappearance of CL, this footage disappeared and is now difficult to find on the North Yorks. Police website.
When judging light levels on that morning, it is useful to compare like for like so here is a clip of the 5:07 cctv
(clip 13 onwards)
and here is a clip of the Ford Focus at 05.42 from the same camera in Lime Court
Old-style light coloured Ford Focus seen braking
Note on the 2nd clip there is a shadow of the building on the right /at the front of the image which falls onto the road. This isn't present in the earlier image.
I believe this is because the Lime Court camera is facing due east and at the time of the later clip 05.42, the sun has risen over the rooftops of the properties on Heworth Road, thus creating shadows. The rising sun is easier to see from the other camera shot of the Ford Focus (see 1st link). It is interesting to compare how dark the Heworth Road images are compared with the ones from the camera angle in Lime Court.
See what you think.
