The reason I asked about witness statements from CB and MS was in response to Holly’s question about why EP took such a heavy-handed approach with CB (given that she wasn’t MM’s alibi) How does Holly know details about what happened to CB?
It appears that a witness statement wasn’t taken from MS.
We don't know if the Police treated CB in a heavy handed way. That assessment is one persons opinion of something that they were not witness to.
CB was almost certainly treated in line with the procedures of the day, which will almost certainly be very similar to the procedures of today.
As far as I'm aware it is not publicly known if Mavis Southgate was interviewed or not. Given that she was MM's alibi, then of course she would have been interviewed. We have no idea if she was treated the same, or differently to CB. I would guess that she was treated roughly the same.
People seem to think that documents like witness statements and photos have been officially released. But this isn't true. It has all been illegally leaked via dodgy and naïve lawyers, via the campaign team and other individuals.
Given that there is no mention of Mavis Southgate on the blue forum, or on the campaign teams official website, well, that indicates that Bamber and his legal team and his supporters have been unable to concoct a conspiracy theory, or a lie, or a set of lies, out of her paperwork, and therefore haven't released any of it.
Just because there is no paperwork for MS on the public internet, doesn't mean that she wasn't interviewed or didn't give a statement. And it doesn't mean she didn't get her house searched either. It just means that Jeremy Bamber hasn't illegally released the paperwork for her.
