you will have to check these two things with Mike - but apparently Jeremy was heard driving away from the farm at 9.30 ISH.
Also I found this
A distant relative of Ralph Bamber, a man by the name of Ralph Neville, was working at whf at the time of the shootings, and he was staying at the caravan park, owned by the Boutflours, and the Eatons, Neville lived in South Africa...
On the night of the shootings, his motor car was found parked up in the driveway of whf...
The reason his car was found there, was because Ralph Neville had been working late in the fields on the evening before the shootings, and he had taken the tractor and trailer, he had been working on, in the fields, back to his digs at Osea road caravan park...
Police were trying to link the hitchhiker statement to him...
What is odd about this though, is that Essex police allowed Neville to collect his car from the drive at whf, later that morning (7th), and as far as is known, by the beginning of September 1985, he had returned to live back in South Africa - why would he be hitchhiking on the morning of the shootings, if the police had given him his car back?
