The murderer, in the mean time, had succeeded in making his escape, and the officers of justice were despatched in pursuit of him, but without effect; for, as he had been for a length of time out of place, a clue to his last residence was not easily found. At length word was brought to town that he was in custody at his native place, Salisbury, to which he had bent his steps, and where he had been recognised by his old master the farmer, who, having heard of the murder, immediately had him scoured.

On the 13th of August he was brought up to Bow Street, in the custody of Taunton the officer, where he underwent an examination, after which he was fully committed to Newgate. He appeared very little affected at his situation, and preserved a sullen silence.

On Friday, September the 16th, he was arraigned at the Old Bailey for the murder of Miss Welchman. The evidence was circumstantial, but conclusive; and, when called on for his defence, he denied the crime with which he was charged, and said that it was not proved the pistols and hat were his. He called no witnesses, and the jury having been charged, retired for a few minutes, and returned with a verdict of Guilty.

The Recorder, after silence had been proclaimed, pronounced the dreadful sentence of the law, which was heard by the prisoner without the slightest emotion.

He was executed on the 19th September with a man named Hollings, who had been convicted of a similar offence in the murder of his step-daughter, to whom he had formed an attachment, notwithstanding his having married her mother; and whom he murdered in the street, at the door of her master, Mr. Cartwright, in Lower Grosvenor Street, because she had refused to accede to his disgusting and lustful propositions.

So great was the public curiosity to see the unfortunate malefactors, that at seven o’clock on the morning of the execution, the Old Bailey and Giltspur Street were crowded to a degree almost unprecedented. Much money was given for indifferent seats at the top of the houses opposite the Debtors’ Door; and carts, waggons, and other vehicles were put in requisition. At a quarter before eight the prisoners were introduced to the Press-yard, for the purpose of having their irons knocked off, accompanied by the Reverend Mr. Cotton and the Reverend Mr. Frere, the latter of whom sat up in constant prayer all the night with Hollings, who joined most fervently in the devotion. Mitchell, who was dressed in black, was first brought out from the cell; he looked pale, and maintained a deportment of sullen resignation; he did not say a word, nor did he betray the slightest symptoms of feeling at his awful situation. The irons being knocked off and the usual ceremony of tying the hands being executed, he lifted his hand as far as he was permitted, and looking up, bowed, and appeared to be in prayer. Hollings stepped forward to the block with great activity. He was, however, very tranquil; and upon being disencumbered of his irons, he addressed the persons around him in nearly the following words: “Here, you see, I stand a victim to passion and barbarity: my crime is great, and I acknowledge the justice of my sentence. But, oh! the unfortunate girl I loved, I adored as one of my own. I have made contrition, and prayed for forgiveness; I resign myself under an impression that Almighty God has heard my prayers, and will forgive me: may you and the world take warning by my example; and here I confess the justice of my fate—receive my soul, O God!” At the last expression his feelings overcame him, and he wept.

The whole of the awful arrangements being complete, the prisoners were ushered to the fatal scaffold. Mitchell was until this time firm and unconcerned; but he now became much agitated, and the horrors of death were strongly portrayed in his countenance. Hollings shook hands with the officers of justice, declared to Mr. Frere that he was quite happy, and mounted the scaffold with great firmness and resignation. The clergymen continued to pray to them until the fatal signal was given, when the drop fell. Mitchell continued in the strongest convulsions for several minutes, and appeared to die very hard.

After they had hung some time, three females were introduced, for the application of the “dead man’s hand,” supposed to remove marks, wens, &c. The first was a young woman of interesting appearance, who was so much affected by the ceremony that she was obliged to be supported.

At nine the bodies were cut down, and sent to St. Bartholomew’s Hospital for dissection.
