I'm unable to find any detailed exact information, Mike. I will keep looking though. The 'hill' comment is indeed interesting and noteworthy.
Yes, it is the key to unravelling this mystery, everyone of us should try to do everything we can, to bring closure to this awful case - I believe that once the locations of the other four graves (in sequence) are made known, that it will simply be a case of feeding that information into ENIGMA, and it will pinpoint the most likely position that Brady disposed of Keith Bennets remains...
As I say, I have two locations earmarked on the moor where Keith's remains are to be found, based on what Hindley said, when she said what she said, but until I find evidence of the locations of the other four graves on the same moor, I cannot be certain of the exact location where Keith is resting. Once I find out the true positions of the other four graves, as deposited there by Brady / Hindley, I will then revisit the moor and take pictures, and only then will it be possible to reveal exactly where the remains of Keith will be/ can be found? I have 100% confidence in being able to find where Keith's remains will be found, once I receive details of where the other four victims bodies were buried during the killing spree of 1963/ 1964...
