If you look at the aerial photos of the two sites where Jane and Ciara were found, you will notice that they were both unsealed roads. They were both sealed shortly after. So, this suggests that whoever killed these girls and dumped them knew that the roads were about to be sealed and that the bodies would be found, since they were laid out on the ground covered with foliage, rather than buried. I have previously written, on other blogs, of the line between Jane and Ciara and how it runs through the corner of St Quentin Ave and Bayview Ave. So it can definitely be stated that the killer researched these locations prior to using them. So, who would know about these plans for the road sealing? Surveyors leap to my mind first, since the killer laid the girls in specific locations EXACTLY 180 degrees to each other. Could the killer be a Surveyor who has been contracted either by the State Govt or Local Government? A Surveyor could work out these locations in his sleep. I wonder if there are any Surveyors Bench Marks near these locations.
Others who might know about the roads could be contractors delivering material, Council planning managers, Town Planners.
Something else to mull over. If you extend the line in both directions, you will find that as it runs south, it crosses through the centre of Collie where Lisa Mott disappeared in Oct 1980 and it also passes very close to Lake Navarino where Annette Deverall was found. She disappeared 29 days before Lisa Mott from Mandurah. Extend the line north and it finishes at a point south of Exmouth intersecting the Tropic of Capricorn.
Also each dumping site was, using the UTM measurements, near a grid line. The grid line for Jane is on Millar road, so rather than dump her in an open area, she was dumped on Woolcoot Rd near a creek. But that spot is still in the actual line between the sites. The same for Pippidinie Rd. Here also the grid line is on the road, so Ciara was dumped in the bush nearby, but still on the line between her and Jane. So with that sort of data, we can draw a profile of where to look for Sarah.
First it must be on a road with a grid line. Then it must be in a spot where the line runs through Bayview. It must also be in an isolated or secluded area. Possibly within an hours drive of Claremont. The cops carried out a search at the Spectacles in their search for Sarah. This area is also on a grid line between Thomas Rd and Anketell Rd, Mandogalup.
In The West, when Ciara was found, the reporter mentioned that her body was found in an area similar to her surname, the same as Jane was. I can put Glennon alongside Eglington, but I can't see where Jane Rimmer fits in the general area where she was found.
