That is my theory as well.
Suzanne Pilley is a great example of a case where it is bang obvious what happened but police never found the body because the area it could be in is too large
I originally thought the timeframe of the whole event was quite short and the relevant points quite compressed, starting with the abduction/removal of LS by PR from the bench, both being in/at the Park, Attack/Assault in/at the Park, Screams, PR kills LS and Dumps in Water/Park or .....Screams....PR Runs off, LS comes to inadvertent harm in Park.
The last couple of days, with release of Croda cctv and after visiting Cctv/Park area, Im pretty much where Mark B and Mrjitty are...
The timeframe is extended by abandonment of LS at/in Park, PR Returns, either in his car but with sheets/bags etc or in diff car...removes LS, drives elsewhere, seen on cctv leaving area and seen re-entering Hull/N Ave 3am ish, maybe 30-90 mins after croda cctv people( esp 1st one and bike person) witness/hear/see removal.
Or returns to Park and relocates LS/LS Body to River/Drain/Concealed Place in Park. Maybe to or from abandoned building.
Im now slightly favouring The first Return/Removal theory as imo it makes sense of the LE's searches of Park and methodology of those searches. LE know LS/PR have at some point been in/at Park. Imo They Know PR returned and then left. Hence reasoning that LS is no longer in Park or is in Water there.
Maybe timescale of arrival and departure at Park means its impossible to have gone too deeply into the park.
Am concerned that no forensics appear to be found in PR's car( despite a theory of cleaning out of car based on supposition , not likely to be able to remove all traces) . If so. Hedve been charged.
Given distance PR could travel in 15min radius, impoosible for LE to search. So searching small areas of park to gain proof of known visitation by pr/ls but knowing / thinkingbnot there
Losing line of thinking but.....please pick away.
