From the first thread we know that Toyah (or perhaps just her car was seen heading northbound through Clifton beach at 1:58 and then Toyah’s vehicle was then later seen at the Wangetti south car park around 2:30...
That doesn’t leave much time for the perp to bring Toyah along the 800m to get to the crime scene, tie up the dog, assault and kill, remove clothing? Remove other items as well...phone, bag etc then walk back to car park and be in a vehicle heading south through Clifton beach only a couple of hours later...
