Staunch supporters of LE... stating that LE is honest, and etc.. some WSers theorize about possibilities the trio could be alive, or that the murderer could be someone different, or that there could be 2 murderers involved, and they are accused of saying LE are therefore incompetent and more. Now it is being asked if police were lying when they answered questions? It doesn't make sense.
Regarding the fire.. in the Tim Bosma case, it is believed he was incinerated beyond recognition, and first put through a 'chipper'.. but his wife still received a small box containing his remains. In this case there were no remains given and no statement from police that remains believed to be the trio were found. If LE can identify TB's remains, and if they can say the remains of all of these people burned were found, then they should also be able to state that the trio was found, if their remains were indeed found.
Could it be that the victims were indeed burned in a fire, but their remains (ashes, bone fragments, teeth, etc.) were removed from the fire pit and disposed of elsewhere? This would explain the comment about searchers not knowing what they were looking for. Perhaps trace amounts of DNA were found in the fire pit - enough to confirm that they must be deceased (not just from hair or fingernails) but not enough to say that the remains had been found. The search for remains continues, but without information about where to search, it becomes a very difficult endeavour. Seems like a plausible theory IMO.
