Hello. I'm a first-time poster too. Like many others here it seems, I'm a Londoner who has been deeply affected emotionally by this particularly haunting and disturbing crime against poor Sarah Everard.
Some random thoughts/observations -
In early media reports (6 days ago) it was suggested that Sarah walked part of her journey home with "another friend". An example link of this here :-
Desperate search to find woman, 33, who vanished on way home in south London
Was this ever discounted/proved wrong? My thought being, was the "friend" the alleged perp, WC? Did he somehow either know her (but this is unlikely as the family have said they didn't previously recognise his name) or he was hanging around Clapham Common and latched onto Sarah during her walk home. Did LE interview him early in the investigation, but he said he was a friend of Sarah and they initially had to take his statement at face value as he was a fellow LE officer? But then his statement didn't stand up under scrutiny?
Secondly, people are speculating on how WC may have coerced Sarah into his car. One thought springs to mind. As someone who has walked home many late evenings across London after a few drinks with friends or at a party, I know one thing for certain: I usually have to stop somewhere along the route for a discreet pee. Is it possible that after Sarah's phone conversation with her boyfriend, she needed to stop in the shadowy areas around Poynder's Court to discreetly squat down behind the bins or similar and pull down her leggings to relieve herself. Did WC happen to drive/walk by at this particular moment and happen upon her at a particularly vulnerable moment for her. A few months back I witnessed a very unfortunate drunk man peeing against a building on a public road just as a van-load of police offers pulled up to the kerb. I noted that they were giving him a very stern talking to and leading him towards their van to as I walked away. Could this have been the 'in' WC used to approach/lure her into his car.
Police were seen searching the drains near Poynder's Court - did they theorise that the perp had disposed of Sarah's phone down the drains here.
How did WC overpower Sarah. Is it possible that as an LE officer he had access to weapons like a taser.
The accusation of indecent exposure towards WC seems significant. It seems highly likely that this was a sexually-motivated crime. If WC was cruising Clapham in a hired car with false number plates looking for victims as previously suggested on this thread, then it's possible that his plan was to find a lone female victim to lure into his car with his warrant card on a pretense of having committed a petty crime such as public drunkeness, outraging public decency, or breaking lockdown rules, and then offer her a sleazy choice. 'it seems you're in an unfortunate situation here young lady, but there is a way out of it for you.' And then unzips his pants etc....It seems likely that this kind of sexual power trip would be a strong motivator for the perp. Some previous victims may even have gone along with this, but the fact that the incident has apparently had such a grim and violent ending suggests that Sarah put up one hell of a fight.
These are horrible things to speculate on, but they seem sadly plausible in our current society. If Sarah has met a violent ending as suspected, then god bless her soul, let her have justice, and may her family and friends have comfort, peace and justice too.
