It's an interesting still image of white coat man outside Costcutter on the morning of the 19th. Is there agreement about who this is? This image doesn't doesn't reveal whether he's still holding the object he seemed to have when passing Heworth Place, or what it was.
Claudia police release new CCTV appeal
After nearly a week of digging into this again, I'm coming the conclusion (like many of you) that the police almost certainly know/strongly suspect who was involved. Because of the media interest/interference and conflict with the local 'community,' I doubt they will let anything out of the bag until they're sure any findings are related to Claudia. They're managing the press around this very carefully.
