It's tiring me out too but I don't think it's settled just because BKs lawyer said it was planned earlier in the Fall. He could have been lied to. In any case, the airline ticket issue date will prove it. There are multiple possibilities:At least we can move to another topic now. The car debate was tiring me out!
1. The car trip was preplanned and coincidental having nothing to do with the murders.
2. The car trip was planned after the murders, in order to have an excuse to get the car out of the area, or because BK needed parental support, or for some other reason.
3. The car trip was preplanned, but the murders were also preplanned to take place on or around Nov 12, with the trip set up ahead of time as an excuse to remove the car/suspect from the area afterwards. It would look normal to leave for Christmas break.
