This has always been a key point for me. How exactly do you carjack someone who doesn't even know where her own car is? How did he know, just from seeing her approach her car, that she wasn't expected back in 10 minutes and would be missed almost instantly?
Exactly my point, speculation is fine (we have to do that in this case) but with common sense and deductive reasoning we should be able to work out the more likely what "probably" happened. Take the possessions as a case in point.
Suzy works Friday goes out with AL on Friday night allegedly loses property (does
not in my opinion despite what AL says in a documentary)
Works Sat morning says nothing to anyone about losing possessions.
Goes to party on Saturday night with close friends says nothing about losing possessions
Goes windsurfing on Sunday afternoon with friends says nothing about losing possessions
Goes to her parents house on Sunday night says nothing about losing possessions
Goes home allegedly speaks to AL (more likely called him from phone box at POW at 10.15pm and drops her stuff then)
Goes home does not see NB
Sees NB in the morning before going to work says nothing about losing possessions
Goes to work sees JC he says that she was "stressed" about losing possessions
There is no evidence or hint that she lost them before Sunday night, JC is 100% convinced she lost them Sunday night.
There is no other evidence that anything else happened but the narrative says she lost them Friday night on the steps of the POW
