There has been NO mention of whether there is a babysitter or not and this is all assumption on my part, but I really had hoped that perhaps Sini and WM had maybe picked the kids up from school, brought them home, had them fed and left them with a sitter, went out for a date as many couples do and came home -possibly after having a drink or two with dinner or friends etc, and they go to sleep. Dad gets up with a very upset Sherin at 3am and things go BAD, dad may have been intoxicated partly or still and he didn't know his limits and before you know it Sherin is gone and 5 hours have passed before he is thinking in a good enough mindset to call LE...
Again, purely speculation, not an ounce of this has been verified or mentioned, but in my mind I can see a substance or something at least semi justifying why the story is so scattered like WM was putting together several different thoughts and why Sini could have slept through what sounds to be a fair bit of commotion.
What came to mind when I initially saw his conditions of release and that he is not to use drugs or alcohol at all and must submit to random urine testing. Where I live this is only ever checked if these are an issue for the person and even more specifically it seems that those are only checked if the person was actually under the influence at the time of their crime (or it has been an issue in the past).
Again, I DO NOT KNOW if WM has these issues, BUT another "story" I have thought of is he woke up at 3am to meet a possible dealer at that tree and something happened during this time frame that resulted in wherever Sherin is now, or, he went out to the tree and the person didn't show up or he heard her awake, went back into the house after 15 mins and she was wanting milk, he took her and put her in the car and called to meet the person, he runs out at 4 am for this meetup and Sherin is still fussy or angry or demanding the milk and he can't deal with it -he is tired, she has ruined his high or stopped a deal from happening and he dumps her...
Again JMO, pure speculation. He doesn't look like he is a substance user, but then again a ton of people don't. I just think for MY MIND it is easier to rationalize abuse and even death occurring when someone is NOT in their right mind because of a substance...
I have SOOOO many possible scenarios in my mind and theoretically, based on what we have been told, they all could fit, which is scary and likely the problem LE is having, they probably also feel they have TOO MANY options as to what happened and have no clue which way is the right way...
Before I had seen the Bond conditions I never even considered a substance could be involved, but with that and then some of the other posts suggesting an affair, financial issues etc made my mind go down this road... I am more than sure that LE knows if he was intoxicated or not and I realize they are being very tight lipped and with the statement earlier it sounds like we should expect it even more. One of our theories will likely be right, and that alone is scary
