The shooting incident which unfolded at Whitehouse farm, was 'sparked off' by 'a combination of factors' which had got 'nothing to do with any possible involvement' of 'Jeremy Bamber'..
One of the contributing factors, involved 'the unstable mind set' of 'more than one of the five victims' - 'Sheila', 'June' and 'Neville'! Another factor was the 'medical functionability' of 'Sheila' and 'June Bamber'..
Also, the fact that on her journey to whf, 'Colin Caffell' may have 'lit the touch paper' by rejecting the possibility of 'he' and 'she', and 'their two children' would 'never be reunited' together as 'a proper family unit'...
There is also, the factor concerning 'the contents' of that 'letter' which 'Colin' had 'written himself, and to which' he had handed it over' to 'Neville' upon arrival at the farmhouse.
