Kemo, I know for a fact... I mean, I suspect, that there were people in Perth before, at and since that time, who had magnetic "taxi" door signs and battery powered roof top "vacant" lights with magnetic bases. These people also had magnetic signs that could "instantly" transform any typical nondescript, late model, white vehicle into a service or amenities vehicle driven by employees of companies such as Western Power, Coke, Telsta, "Live Tissue Transfer" , Perth Gas and Plumbing, Rent-a-plant, Perth Security Services and various others.
These people also had numerous sets of stolen number-plates which they would swap with the plates of whichever vehicle was used for whatever they used it for, for the duration of whatever it was they were doing, and then dispose, and "western power" and "telstra" overalls, hardhats and fluro vests, fluro "police" tape (like what you put around crime scenes) and security guard uniforms complete with walky talkies, hand cuffs and fake id.
Perth is a small city, relatively, but of course as with any large town or city in the world, organized crime will invariably start staking out their territories and niches, and I am sure these magnetic signs were used for all manners of crimes and unlawful behavior, and probably still are...
These syndicates almost all have interstate roots and/or connections and the syndicates are surprisingly interactive considering the usual borderline-cliche rivalry (though such dealings often end in normal criminally vengeful fashion when they go wrong). With Perth being as isolated as what it is, and the major transport industry between here and the other major Australian cities and ports being long haul trucking, it is also possible that if the killer/ killers had access to these signs and were in the transport industry, and they could easily be responsible for numerous unsolved murders and disappearances.
JBM was investigated for the CSK'sn but ruled out. The Falconio murder took place in a "central"meet up point for interstate drug dealings and was in the trucking industry. The people with the magnetic signs are truckies and bikies who traffic drugs interstate, and a few of them are rampant bisexual homophobes (a paradox I know, but hypocrisy is a prevailing trait of sexual sadists and psychopaths, is it not?)who network with other like-minded ****s via their cbr networks, which is the medium through which they conduct their drug dealings and other criminal activity too, and through which they can also monitor police activity (or could before the cops switched to predominantly mobile phone communications when setting up busts and stings).
They tip each other off about backpackers and hitch-hikers thumbing for lifts and know every single parking spot and rest bay between all the major cities.
They network with other truckies, bikies, taxi drivers, small plane pilots, "wandering campers" and even cops and military personnel, whom they impersonate on other required occasions (fYI not all truckies and bikies look like their cliche counterparts. It all depends on their line of work, and of course their "associates" come from all walks of life).
If you look at the lists, there definitely appear to be "clumps" of killings and disappearances. Many cases have similarities, but then they will have anomalies that don't add up because the victim doesn't fit the right profile or the MO is different or, of course, they are geographically hundreds or thousands of kilometers apart.
I still believe there is more than one killer and that these killers sometimes work separately, sometimes together and sometimes with other associates which is why they always seem to be locals with knowledge of the area and/or of the victims and why the victim profiles seem to overlap as well as MO's and locations...
All this is just "IMO" of course...
