One night he, with some others, crossing the park a fray happened between them and one John Stone, which as Casey affirmed at his death, was occasioned by the prosecutor Stone offering very great indecencies to him, upon which they in a fury beat and abused him, from the abhorrence they pretended to have for that beastly and unnatural sin of sodomy.  Whether this was really the case or no is hard to determine; all who were concerned in it with Casey being indicted (though not apprehended) with him, and their evidence consequently taken.  However that matter was, Stone the prosecutor told a dreadful story on Casey’s trial.  He said the four men attacked him crossing the Park, who attacked, beat and cruelly trod upon and wounded him, taking from him at the same time his hat, wig, neck-cloth and five shillings in money; and that upon his arising and endeavouring to follow them, they turned back, stamped upon him, broke one of his ribs, and told him that if he attempted to stir, they would seize him and swear sodomy upon him.  On this indictment Casey was convicted and ordered for execution, notwithstanding all the intercession his friends could make.

While under sentence he complained heavily of the pains a certain corporal had taken in preparing and pressing the evidence against him.  He said his diligence proceeded not from any desire of doing justice, or for his guilt, but from an old grudge he owed their family, from Casey’s father threatening to prosecute him for a rape committed on his daughter, then very young, and attended with very cruel circumstances; and which even the corporal himself had in part owned in a letter which he had written to the said Casey’s father.  However, while he lay in Newgate, he seemed heartily affected with sorrow for his misspent life, which he said was consumed as is too frequent among soldiers, either in idleness or vice.  He added, that in Spain he had made serious resolutions of amendment with himself, but was hindered from performing them by his companions, who were continually seducing him into his old courses.  When he found that all hopes of life were lost, he disposed himself to submit with decency to his fate, which disposition he preserved to the last.

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.
