All this is just wild speculation though isn't it? Not all that helpful, and as pdqs own posts show, can veer wildly from assertions of a professional hit squad taking down a potential terrorist to a hit organised or participated in by family members over a family feud. And interesting though it might be to indulge in such flights of fancy, all it does is obscure the tragedy of a family slaughtered, and very young kids orphaned in a second.
The level of speculation reminds me a lot of the sad case of the murder of Joanna Yates, and the absolutely scandalous misbehaviour of the media in naming the landlord and subsequent character assassination of Christopher Jeffries..............
