Police have the commodore fibres, but there is nothing to say there was multiple vehicles used in each abduction, and overall in each abduction. Obviously police would think so. They pulled up POIs in example Hyundai etc. So police have fibres, DNA, and some plastic coated chord. I think Telstra technicians fitting in house cable networks may have used commodore station wagons. Vans arent conducive always to underground car parks in multi-story buildings. Although the van was used at Karrakatta according reports. From the description of the plastic coated rope, it would be lubricated with chemicals that assist it to draw phone cable through conduits in tight bends. So it could be a Telstra technician with access to multiple vehicles day to day. A Telstra technician that taps victims phones maybe ???
