Another thing, i think i know where this whole 'witness protection' thing started. The other night on one of the trubute pages discussion boards (before they were removed) i saw someone post and simply ask 'was this family on a witness protection scheme at all' (or something similar wording to that) and i dont remember seeing any replys to that. Then somone has mentioned it on another FB page saying something like 'Allegedly this family was/could have been on a witness protection scheme' but in reality i dont believe anyone said that they were, someone just simply put the question out there. So you can see how one little bit of information can get quickly distorted when somone just relays only part of the information or just key words and it ends up being far from what was said.
It could be a troll, could be someone like us trying to figure things out, or it could be someone close wanting to divert the case in another direction for other reasons.
