At the place of execution he behaved with great composure and said that as he had heard he was accused in the world of having robbed and murdered a woman in Hyde Park, he judged it proper to discharge his conscience by declaring that he knew nothing of the murder, but said nothing as to the robbery. At the time of his death, which was on the 11th of September, 1721, he was about twenty years of age, and according to the character his officers gave him, a very quiet and orderly young man. He left behind him a paper to be published to the world, which as he was a dying man he averred to be the truth.
A copy of a paper left by William Casey.
Good People, I am now brought to this place to suffer a shameful and ignominious death, and of all such unhappy persons, 'tis expected by the world that they should either say something at their death, or leave some account behind them. And having that which more nearly concerns me, viz., the care of my immortal soul, I choose rather to leave these lines behind me than to waste my few precious moments in talking to the multitude. First, I declare, I die like a member, though a very unworthy one, of the Church of England as by Law established, the principles of which my now unhappy father took an early care to instruct me in. And next for the robbery of Mr. Stone, for which I am now brought to this fatal place. I solemnly do declare to God and the world, that I never had the value of one halfpenny from him, and that the occasion of his being so ill-used was that he offered to me that detestable and crying sin of sodomy.
I take this opportunity, with almost my last breath, to give my hearty thanks to the honourable Col. Pitts, and Col. Pagitt, for their endeavours to save my life, and indeed I had some small hopes that his Majesty, in consideration of the services of my whole family, having all been faithful soldiers and servants to the Crown of England, would have extended one branch of his mercy to me, and have sent me to have served him in another country. But welcome be the Grace of God, I am resigned to His will, and die in charity with all men, forgiving, hoping to be forgiven myself, through the merits of my blessed Saviour Jesus Christ. I hope, and make it my earnest request that nobody will be so little Christian as to reflect on my aged parents, wife, brother, or sisters, for my untimely end. And I pray God, into whose hands I commend my spirit, that the great number of sodomites in and about this City and suburbs, may not bring down the same judgement from Heaven as fell on Sodom and Gomorrah.
William Casey.
