Completely thinking out loud here but on the basis the stalking theory had some legs to it could it be someone she has met through work? Supplier to the school? Parent who has spotted her at the school gate (but not necessarily a parent of a child in her class). Even someone local-ish who maybe saw her at the same time everyday so was able to track her? The problem with theory as I think has already been mentioned is that unless she was aware of it, it will be exceptionally difficult to track him. Expect that if it IS a stalker then I imagine some level of painstaking scrolling back through cctv/ANPR might be able to spot the same person/car over a historic period which might prove more fruitful in terms of tracking his onward movements?
It seems so brazen to attack so close to her flat. But perhaps he wasn’t aware of a date but was just regularly waiting outside her flat, but on this occasion spotted her somewhat “dressed up” as it were, for a date. So decided to strike in that moment? He waited a few seconds to check no one else was around, but he maybe already knew she wasn’t about to be followed by a partner (who might have just been locking up or something).
I have also been wondering whether or not the item in the hands of the man on the cctv is some sort of “trophy” from her, a mask she was wearing/carrying perhaps, or a shawl/scarf to keep the chill off? Could be the reason the police haven’t released any info on her clothing (although if they have the attack on CCTV then they don’t need to release this info as they can accurately surmise she was not spotted by anyone as she was not walking alone for any length of time so they are not going to put unnecessary information into the public domain). All JMO - trying to figure out the sequence of events, but also the reasoning.
It doesn’t seem like it had a sexual motive, but equally the covering of the body suggests some kind of care taken over the body which would be strange for a “hit” type action because why take the risk of having around any longer than necessary over a dead body once that deed is done. That is the bit that doesn’t add up to me. If it was completely dispassionate wouldn’t the perpetrator just do the deed and leave?
It’s all so baffling. but I really hope that cctv man is found soon.
(And again - big up to CCTV surveillance or the police would be nowhere).
