I think it’s time to consider that PR is not involved in LS disappearance at all. I know we all would like to believe he knows what has happened to her but I don’t believe he does.
He has come to the attention of the LE during there investigation into LS. They have probably seen him acting suspiciously while reviewing the cctv footage and brought him in for questioning. His prints and dna would be taken and this is what linked him to the offences he is charged with.
As the LE continue to search in a very narrow area and that no one else has been arrested this would lead me to believe that LE think LS has just wondered off and maybe fallen out of sight and the cold weather has unfortunately led to something unthinkable happening. The authorities are still saying it is a missing persons investigation and that it obviously what the evidence is leading them to believe and not abduction or worse.
I don’t agree at all.
