I have a theory on this;
I think a guy she liked was at Conti and she waited outside hoping that when this guy leaves he'd approach her. He didn't so she left. I think she either got into a cab or car out the front or walked around the corner onto a deserted Gugeri St and got in a car there.
She could have met someone earlier in the night and had a pre-arranged meeting but why did she agree to go to Club (locals refer to CBV as Club, Clubba or Club Bay Spew)? I guess it's possible she planned to wait in line (there was always a line at that time of night) and once they got close to getting in, make her excuses and bail for her rendezvous. The problem I have with this is even if she didn't tell her friends they would have seen him talking to her. He would have come up on Macro's radar. I'm also quite confident our guy doesn't meet his victims in bars on the night of the murders.
She may have been seeing someone and had a pre-arranged meeting. I believe if this was true, a) Macro would have found out through phone records, and b) her friend in the CIA doco wouldn't have been so sure JR "just wanted to meet someone".
Could have she gone to another club? Subiaco maybe, which is closer to home. But she would have got a lift home and then got a taxi from Shenton Park.
I wonder what her friends thought she was doing? Conti closing, didn't like Club, could have stayed in the line at Club, decided to stay out. Surely her friends were asking themselves what JR's options were?
What you have got to understand is that for a girl Jane's age back then, it was not all that uncommon for them to ask for a lift from a complete stranger in a car driving by or for them to ask random people if they could get a lift to such and such a place. For example, I was at Inaloo cinemas in the mid 90's, possibly 95 or 96. I was either 15 or 16 at the time and I was waiting outside with some friends and I had a number of girls approach me that night asking me if I had a car and for a lift to Claremont. I was quite tall for my age, which is why I think they asked if I had a car.
JR waiting outside the sidewalk presents the perfect opportunity for the CSK to driving past patrolling the area for a victim. All he would had to have done is offer a lift, in a nice friendly manner. JR being under the influence of alcohol, IMO would have readily accepted the lift.
You have to reason the possibilities of how the CSK captured his victims and it comes down to a number of options, but you then have to prioritize those options to which is most likely and unlikely but a possibility.
1. JR was offered a lift by the CSK who was driving past and she accepted the lift.
2. JR caught a Taxi and the driver was the CSK
3. JR walked away and down the street, was blitz attacked and bundled into a car/van
4. JR walked away and was offered a lift somewhere else and that person was the CSK.
Now, to me the first two scenarios are the most likely, and all of the other ones are unlikely but possible. When you consider that DNA has been taken from 2,500 Taxi drivers, 900 Taxis were forensically examined and all Taxi drivers backgrounds were checked and any drivers with questionable backgrounds were elevated as POI's, then investigated, interviewed more thoroughly. This all turned up nothing. I would say with the amount of work that was done on the Taxi industry and that the idea that JR caught a legitimate Taxi and the driver was the CSK, has been investigated thoroughly enough to exclude it in this case. An illegitimate Taxi is another line of inquiry altogether, the possibilities and amount of investigate work to be able to prove this did or did not happen is incomprehensible.
The other likely scenario is 1. that one that JR was offered a lift by the CSK. Now, one would reason that the timing was too perfect for the CSK who just happened to be driving past at the time saw JR and offered her a lift, then murdered her etc. There has to be some sort of patrolling the streets going on. Whether or not it was just sitting, waiting and watching or actual patrolling the area looking for a victim is not clear. But you have to agree if it did happen this way it was no coincidence. The CSK could easily have developed the skills over period of time to talk to girls and say the right things to coax them into his vehicle. He may have met with a lot of "**** offs" and generally at that time of night, when people are intoxicated they have sketchy memories about such things. In relation to this scenario, a major surveillance operation was conducted and vehicle registration numbers were recorded every Friday and Saturday nights between the key times that the girls went missing. A number of vehicle registration numbers were identified as passing through the same area multiple times during those key times. Unfortunately this was after all three girls went missing. A key suspect was obtained through this surveillance.
Lets not forget that it is just as important to disprove something then it is to prove something. In the Claremont case, I believe there is a lot of disproving going on, to prove that the method in which they believe the girls were snatched actually happened.
If the girls were snatched using method 3 or 4, one would reason that someone surely, saw or heard something when they were being forcefully abducted from the streets. It it just too risky a method to use for someone that is as organised and meticulous in there planning as the CSK was. It is much safer to simply offer them a lift, if they so say then no one thinks twice about it, if they say yes, then the CSK has a potential victim.
