When Sharon called the Peterson house about noon, Chris answered the phone and hemmed and hawed when Sharon asked to speak with Stacy. DP took the phone and told Sharon that Stacy had gone to visit her grandfather. Sharon explained that she had treats for the children and DP said he'd bring them over after lunch. He evidently didn't ask then if she could babysit. It was only when DP took the children over to Sharon's he asked Sharon if she could babysit for a few minutes. I kind of think that whatever errand DP had to run, that it was something he came up with on the spur of the moment.
I've always thought that DP used that 15 minutes to move something at the house.......maybe move the container from the basement to the master bedroom. Whatever he did, didn't take too long.
I think it's important to know if Sharon babysat for all four children or only the two younger ones. If only the two little ones, where were the boys? When DP was gone for those 15 minutes, did he leave in his car to go somewhere? Or was he at home?
I wish we knew more about the floor plan of that house. From the tour of the house that DP gave a few weeks ago, the basement is finished with one or two bedrooms, a bathroom, and a family room/recreation room. I think one of the older boys bedrooms is in the basement. What I want to know is where the stairs are from the upstairs - master bedroom area - to the downstairs and the garage. I want to know if it's possible for someone - if all the children are occupied playing in their bedrooms or watching tv in the family room - to get from the master bedroom to the garage un-noticed?
Could DP have moved Stacy from the master bedroom to the garage un-noticed, and then, once he checked to see that none of the neighbors were outside, from the garage to her car in the driveway? He probably would have had her wrapped in a blanket or something so if anyone did see him he could pass it off as putting items in the car for the dry cleaners. Then, he moved her car to the airport. If he was able to move her from the house to her car and then the car to the airport, un-noticed, he would have been in the clear as far as the children were concerned. In response to a "where's mom" question, he could tell the older boys that they had an argument and Stacy stormed out of the house, saying she was going to her grandfather's.
That would account for the cadaver dogs hitting on Stacy's car.
