Excellent post Smooth. I, like you, came to the conclusion that DS Sr was likely somehow involved in pretty much the same way. The strange alibi comment and then the raid. I also see him as a sarcastic, and non caring individual when it comes to the subject of Michelle's disappearance. His smart azz comments after the raid, during the walk from the courthouse etc.
When I first heard the rumour on that radio show about him taking his boat out the day after Michelle went missing and LE were searching that lake possibly as a result of a tip that he was in that area with a boat, my first reaction, based on my opinion of him, was..."she's not in that lake, or any lake for that matter". He seems like someone who likes to play games and taking out that boat was just a diversionary game to him IMO.
It is odd to me that on the very next day that the mother of the children, who were in their care at the time, goes missing, the father of those children goes to "work" miles away and the grandfather goes out with his boat. Both men had likely already been questioned by LE at this point so they had to know the focus was on one or both of them. It seemed more like a look this way...no look that way type of scenario. Both of those men acted very peculiarily that day. For a reason IMO. To throw off the search for Michelle. To give LE some alternate thoughts and locations to look at rather than just the obvious, within a few miles of the crime scene. Question is...where is the crime scene? If the cadaver dogs have not hit on anything in either home or any vehicle or boat associated with either of them, was she still alive before meeting her fate wherever she may have been left?
For those that think this may have been premeditated, I can't help but think of the Summer Inman case. A young mother, killed by her ex and his parents because she dared to move on and seek custody of the children. A bumbling crime for sure with lots of errors and circumstantial evidence but the body would not ever have been found if not for the mother-in-law cracking under the pressure. And considering they killed her and disposed of her within minutes, no cadaver evidence was present either.
MOO
