BBM - We know this is in fact not the case? Pardon? What is not the case and who is
"we"? Unproven in a court of law that is.

LE know truths but cannot say for obvious reasons. Alleged doesn't mean it ain't so. HTH.
Interesting that there were so many reporters reporting on this case, and they all poisoned the water hole, printing all the same information, just worded differently and coming to the same theories/conclusions in their reports, hmm. What they were told by LE was all fabricated? Some may question sources close to the case but those sources most likely are valid and reliable sources. Reporters have a reputation to uphold, therefore they are going to scout out sources for truths not fairy tales. Their first line of defence they will go to is LE. Many sources happen to be coroners, specialists, detectives, witnesses, family and/or friends.
Regarding CN, interestingly enough Leitch said,
“We don’t usually arrest co-operating witnesses.” Apparently CN was arrested because she did not cooperate. Sounds like after her arrest she cooperated and she implicated herself (and probably DM also). Whatever CN told LE, they obviously felt the need to go to her parents home and take away a good deal of boxes and bags. What did CN tell LE they would find as evidence in her parents house? ALL MOO.
