Interesting post, a lot of time has elapsed between the disappearance of Suzy Lamplugh and the extensive search carried out in 2014.
The canal & river trust confirmed that the canal (back then) was dredged approximately every 5 years. Also that (again back then) the deposits were dumped at a convenient site along the side of the canal.
Two questions spring to mind immediately:
1. Did the police check the dates when dredging took place?
2. Has the rate of decay (both human remains & the suitcase) been taken into account.
On the second subject, the PoW pub, according to the staff the police took a cursory look, no detailed examination actually took place.
Both the canal & the PoW pub were put forward by former Met Police officers.
I would be interested to know what source you have for the staff, did any of them speak to you are do you have some published quote for this? I spoke to the person who was there when DV searched the POW and he told me that the police definitely searched the cellar a while after DV had spoken to the police. The question is did they tell DV they did this or did they not bother to tell him? some months after his book came out he was saying on a YouTube broadcast that he was still wanting them to look there but at the time of the YouTube show they already had. The question is did he know that or not? The other fact I find interesting is that JD wanted the canal searched DV wanted the POW cellar searched and both have been done but that does not seem to be enough to satisfy people or have I got that wrong? Both sites are extremely unlikely in my view. lets play devils advocate for a second IF she was deposited at either site and then moved how practical could that have been? neither the acting landlord KH or JC knew London well. I think if SL had been dumped at the canal her body would have surfaced (imo)
The acting landlord was married and had staff working there even if we take the brilliant research that DV did (yes it was brilliant research despite my misgivings about other things) who knew that a stock check had taken place or that the regular landlord was away? nobody until DV found that out so credit where credit is due. But IF SL had met her fate at the POW that raises some very important points that are hard to theorise away.
What did he do with the body in broad daylight?
He was married how did his wife not know about it?
How did he move or conceal the body whilst running a pub as he was in charge temporarily.
he can't have left the body there, in July it would been obvious and smelt terrible
If she did go to the POW and not to either Stevenage Road or Shorrolds Road and met her fate there we must by logic dismiss all the alleged sightings at Stevenage Road, Shorrolds Road and driving down the Fulham palace road seen by Barbara Whitfield at 2.45pm. If her car was driven there by the perp/perps we must dismiss Wendy Jones who saw the car in Stevenage Road at about 12.40pm and it was still there later when she came home later that afternoon and was seen by a taxi driver at 2pm and again by Leo Mahon when he came home so about 5.15 - 5.30pm. If Wendy Jones was wrong (and i think she was 100% spot on about seeing the white fiesta at 12.40-45pm) then there is no way SL went to the POW to meet her fate and then for her car to then be 1.4 miles away taken there by KH the timings do not fit and are in fact impossible. How could SL leave the office at say 12.30pm get to the POW by 12.45pm and then for Wendy Jones to see her car before leaving for the bank with her friend at 12.45pm Its impossible. What are the chances of ALL of these sighting being bogus? I would suggest its VERY unlikely that all of them can be disregarded. The question is can we prove which ones did happen and which ones did not as they cannot all be true can they?
Re the canal
The canal was 4 feet deep so body being concealed unlikely.
Dredged regularly still there post 1986? very unlikely I think.
I'm no forensic scientist but surely a body would decompose and the gases in the gut etc (sorry to be so gross) would force the body to the surface i'm sure I have read other cases where this has happened.
In my opinion its extremely unlikely that SL was deposited at either site.
For what it's worth i think a lot of what DV found out is true, helpful and fills in many of the gaps in what really happened, my issue with his book is that he is obviously thinking SL met her fate at the POW either by accident or some unforeseen altercation. The issue I have is that having suggested that scenario he seems to be trying to fit his theory to fit that and i simply do not think the facts support it. If there were no sightings and her car randomly turned up at Stevenage Road later that afternoon I would think he is bang on but there are far too many other things that need explaining away for that to be in play.
