I thought I saw the picture posted by papertrail, but now can't find it. I have a theory that may include the person you once suspected petedavo.
I apologise as relevant thread with newpaper posts of JC's last known movements which I was going to reply to, I now can't find at the moment. Having trouble navigating.
By "How"and Why" ?, I meant how and why did the car end up upside down 50m west of the Cottesloe Groyne, with doors shut, windows up, lights on, crushed roof to almost the top of doors, and the back seat washed up on a nearby beach.
I have seen previous posts that seemed to agree the car must have been driven down the access beach ramp across the sand and into the water. The only other logical way it ma have entered the water is to have been driven off the groyne, which seemed to be suggested by the police at the time.
I lived in a share house a few houses up from the Cott Beach ramp when I first moved to Perth in the early 80's for post grad at UWA. I swam every morning for 2 years winter and summer around the pylon to end of groyne and back, although we had moved by 1988. IMO it would have been almost impossible for the car to be driven on sand and not get bogged in sea at door level. There could be no roof damage, there was no big sea, we have only one tide a day and little if any tidal movement to move it where it was found. You could see in the photo after it was towed to shore that the sea was small that morning.
Also it would have been almost impossible for it to be driven off the end of Groyne. In those day if I remember correctly, only a 4WD, driving on sand could reach the groyne and the only vechicle I have ever seen on the gryone if the beach lifeguard's 4WD. The beach is floodlit all night, next to Marine Parade which even at 2.00 am would have cars on it, along with people possible observing from house or walking and the noise of something revving down the groyne and crashing into rocks would have been heard by hundreds.
There was no noise and no sightings even under floodlights and close to residents.
"How?" This is not even logical but others have said think out of the box and some may have suggested this. IMO the car has been placed by a boat or some sort of floating barge. At the time in 1988, Perth was laying the first undersea telecommunications cable to transverse the Indian Ocean to Africa (via a small island off Maldives). Would have BRE had access to any of this equipment? He would have only been 18 1/2, but out of school and working for 18 months.
"Why?" Two days after JC disappeared and with great difficultly and danger from being seen why was it important that the car was found, It had its lights on and was a beacon begging to be found only hours after it was put in the water.
IMO the answer illogically again has to be connected with it being in the Westerly direction, as a beacon. I also think the book with the electrical diagram found in the building opp KK may be a clue. It may not simple be just North, south east and west. What are the degrees between the lines in that diagram? Again, I'm having an epic fail at trying to copy and past the article with the circular winding diagram in it. Do other bodies that have been found, including GR fit in with this? Was JC stalked and abducted for a group who had their own secret signals? Was going to Iona something to do with her abduction?
"Who"? in my next post.
