Actually,Vic DID state on the forum that the relatives believed that Nevill had made his way to the kitchen in order to reach the panic button. This caused a long debate between Vic and Caroline as Jeremy had said that the panic button was installed post murders,at the same time the burglar alarm was installed. Vic was adamant it was installed 'pre' murders and he eventually apologised after one of the family phoned him and told him that it was indeed installed 'post' murders in the presence of Jeremy himself. The posts in question should be on the forum somewhere.
