taking on board all discussed in last few comments, myself i believe it more likely that the cases of SS, JR & CG are actually connected AND would like to add - that despite all/any(?) searches made for the missing girls - JR & CG were NOT "found" as a consequence, but merely stumbled upon by chance! therefore i do not give a rats to whether paul ferguson may have alluded to the killer having wanted his victims found ...we are ALL alluding... but sensibly, as long as the killer could not be connected to his crimes I believe he probably cared NOT as to whether they were found.
the sites as i have seen in photos are midst some very harsh looking country ... where perhaps someone, some day, might also just accidentally stumble upon the remains of SS
...as i elaborated on in my recent post #1417

As you can see from the following description even though the Kwinana Freeway goes through there are a lot of undeveloped areas with swamps. I have travelled to Mandurah for years originally it was a cut lunch and water bag job with a stop of at the little shop on the Old Mandurah Rd for ice cream, it is still a bit back woods if you go the Kargotich Rd route anything could be out there just off road.
South of the Rowley Road diamond interchange, development is sparse, except in Bertram, southwest of the Thomas Road interchange. The freeway progresses through swampy rural land for 3.4 kilometres (2.1 mi),[SUP]
[17][/SUP] passing by Lake Balmanup in
Wandi on its way to the diamond interchange at Anketell Road. The Kwinana Freeway continues south along the edge of Jandakot Regional Park, near to The Spectacles Wetlands, reaching
Thomas Road after another 2.4 kilometres (1.5 mi).[SUP]
[17][/SUP] The Mandurah rail line deviates from the freeway median 1 kilometre (0.62 mi)[SUP]
[17][/SUP] north of the interchange, thereafter travelling south-west towards
Rockingham. From Thomas Road to the next interchange at Mortimer Road, 2.7 kilometres (1.7 mi)[SUP]
[17][/SUP] further south, the land to the west of the freeway in Bertram has been developed into a residential area. After the latter interchange, development again becomes sparse, as the freeway travels south near swampland and bodies of water, including Folly Pool and Maramanup Pool. The next interchanges are with Mundijong Road after 4.7 kilometres (2.9 mi),[SUP]
[17][/SUP] Safety Bay Road after another 3.9 kilometres (2.4 mi),[SUP]
[17][/SUP] and Karnup Road following a further 5.2 kilometres (3.2 mi).[SUP]
[17][/SUP] There is a pocket of newly developed urban land near Safety Bay Road, south of the freeway.( Wikiped)
