So what are the facts in this case. Sadly with all the ideas that have been flying around, they remain substantially the same, but after 27 pages of the thread they could stand another airing. I'd be really grateful if Sleuthers can add any proper facts that can be verified from news reports or video captures, because I make no secret that I'm too lazy to trawl through those 27 pages.
On 16 September 2001, a 23 year old Italian national, resident in Richmond, Surrey is travelling on London Underground District Line with a younger companion [20] of the same nationality. They have with them a number of suitcases, as they are changing residence. The older man starts to feel unwell as they approach Bow Road Station, and the pair disembark with their suitcases. The older guy instructs the younger, who is unfamiliar with London, to remain in the station with the luggage while he looks for a public convenience, not an easy task in post-lockdown London.
We know he takes the escalator and exits the station, he vomits just outside, then turns right, when nothing more is seen of him.
Meanwhile, the younger guy waits patiently with the luggage for some time, before calling the Italian family of the older man and then the police.
That was the case September 16, and it remains substantially the case today.
We have no indication about his mental state, but it does appear that he was ill. We have no reliable indication of his background, except that he was a native Italian, resident in London for three years and working as a waiter. After nearly a month, we don't know his prior address, or the address of his destination, or the contents of his suitcases or whether he was carrying his ID in the backpack shown on CCTV. It seems to me we know diddly-squat that's verifiable.
