I do not even think the 3am timeline is true. This seems to be a perp's favorite time to pick to report to LE - it is always 3am. I don't think anything happened in the garage other than Sherin was placed there, dead, until a plan was hatched and clean up begun. I think WM mentioned the garage in case LE detected evidence in there, as in cadaver dogs hitting on where he initially placed her body before leaving the house. I think that the reason we are hearing "I believed that she was dead" is because LE would remind him that, not being a medical professional of any sort, he could not say with 100% certainty that she was dead. He knew she was, but he would have to admit that he is not qualified to make that call. Therefore, he could only state that he believed her to be dead. None of us know how deep into the culvert the body was located. I suggest that it could very well be that a cursory peek into the culvert would not reveal a body 50 feet into that dark, little tunnel even with a flashlight and that it is more than likely a fact that the body was there all along. I think it is best to not complicate known facts with theories of 3rd parties involved in moving a dead child's body from one hiding spot to place it in another. The net has photos taken by rubber-neckers of the culvert, complete with close ups of maggots. To my untrained eye after matching up the photos with larvae stages online, I think there were maggots in the end stage which is about 9 days. I know it may depend on the exact type of fly, but this is my own unscientific opinion for reference. Some of the maggots were reported to be alive - still. Of course, there could have been prior infestation and those maggots are gone as well as earlier larvae stage development present. I do not write this to start a maggot war. I do not think she choked to death on milk. I think the cause of her death is the reason that 911 was not called, because it was not an accident.
