the suspect has been shown to plan in detailThe problem is we don't quite know what evidence we can trust. My thinking was the abduction took place sometime after Gerry's check and before Kate's. The moving door issue leads me to thinking it was sometime around Gerry's visit. For the door to have moved again by the time Oldfield did his check, it seems either the window was open to move it or someone opened it again after Gerry left amd was in there at the tim. Or, if Gerry didn't actually set eyes on MM (I know he says he did, but I'm just thinking what if...) when he did his check then it opens the window from any time from when they left the apartment around 8.30.
suspect has apparently visited a home before committing the actual crime, e.g. to work out the options for entering the apt.
if the same was done in this case, suspect would know the meal start time, and the frequent but apparently unpredictable times of each parent getting up to walk up past apt5A.
food arriving is a good way of knowing people are going to stay put at a meal table for a while.
one of only 2 times all 9 of the group were at the table was when they were eating their starters for about 10 minutes - between tanner arriving back at the table, after her first check, and oldfield/o'brien leaving for their check at about 9:30.
ideal place to observe all this, and close to apt5a would be the balcony of the empty apt5c
