The word ‘killed’ is a rarity found on headstones, from my experience of visits to cemeteries. It does cause this writer to step back, consider, and, in the case of John Flanagen, do some further investigartion.

I have previously written as to the use of the word ‘kill’. I had difficulty in its use in a non-intentional setting. It is interesting that among the options available as to outcome of an inquest, the only ‘kill’ is ‘unlawful killing’ – that is one way of avoiding any confusion as to the interpretation of the word ‘kill’.
