These were damnatory facts which well supported the prosecution. The prisoner made an elaborate defence, in which he sought to vilify the character of the deceased as the seducer of an innocent girl to whom he (Hocker) had been fondly attached. When her ruin was discovered her brother panted for revenge. Hocker, whose skill in counterfeiting handwriting was known, was asked to fabricate a letter making an assignation with Delarue in a lonely part of Hampstead. Hocker and the brother went to the spot, where the latter left him to meet his sister's seducer alone. Soon afterwards Hocker heard cries of "murder," and proceeding to where they came from, found Delarue dead, slain by the furious brother. Hocker was so overcome, feeling himself the principal cause of the tragedy, that he rushed to a slaughter-house in Hampstead and purposely stained his clothes with blood. Such an extravagant defence did not weigh with judge or jury; the first summed up dead against the prisoner, and the latter, after retiring for ten minutes, found him guilty. Hocker's conduct in Newgate while under
sentence of death was most extraordinary. He drew up several long statements, containing narratives purely fictitious, imputing crimes to his victim, and repeating his line of defence, that Delarue had suffered by the hands of imaginary outraged brothers acting as the avengers of females deeply injured by him. Hocker made several pretended confessions and revelations, all of which were proved to be absolutely false by the police on inquiry. His demeanour was a strange compound of wickedness, falsehood, and deceit. But at the fatal hour his hardihood forsook him, and he was almost insensible when taken out of his cell for execution. Restoratives were applied, but he was in a fainting condition when tied, and had to be supported by the assistant executioner while Calcraft adjusted the noose.
There was an epidemic of murder in the United Kingdom about 1848-9. In November of the first-named year occurred the wholesale slaughter of the Jermys in their house, Stanfield Hall, by the miscreant Rush. Soon afterwards, in Gloucestershire, a maidservant, Sarah Thomas, murdered her mistress, an aged woman, by beating out her brains with a stone. Next year John Gleeson Wilson, at Liverpool, murdered a woman, Ann Henrichson, also a maidservant and two children; while in Ireland a wife dashed out her husband's brains with a hammer. London did not escape the contagion, and prominent among the detestable crimes of the
period stands that of the Mannings at Bermondsey. These great criminals suffered at Horsemonger Lane Gaol, but they were tried at the Central Criminal Court, and were for some time inmates of Newgate. Their victim was a man named Patrick O'Connor, a Custom-House gauger, who had been a suitor of Marie de Roux before she became Mrs. Manning. Marie de Roux up to the time of her marriage had been in service as lady's-maid to Lady Blantyre, daughter of the Duchess of Sutherland, and Manning hoped to get some small Government appointment through his wife's interest. He had failed in this as well as in the business of a publican, which he had at one time adopted. After the marriage a close intimacy was still maintained between O'Connor and the Mannings. He lived at Mile End, whence he walked often to call at No. 3, Minver Place, Bermondsey, the residence of his old love. O'Connor was a man of substance. He had long followed the profitable trade of a money-lender, and by dint of usurious interest on small sums advanced to needy neighbours, had amassed as much as ten thousand pounds. His wealth was well known to "Maria," as he called Mrs. Manning, who made several ineffectual attempts to get money out of him. At last this fiendish woman made up her mind to murder O'Connor and appropriate all his possessions. Her husband, to whom she coolly confided her intention, a heavy brutish fellow, was yet aghast at his wife's resolve, and tried hard to dissuade her
from her bad purpose. In his confession after sentence he declared that she plied him well with brandy at this period, and that during the whole time he was never in his right senses. Meanwhile this woman, unflinching in her cold, bloody determination, carefully laid all her plans for the consummation of the deed.
One fine afternoon in August, O'Connor was met walking in the direction of Bermondsey. He was dressed with particular care, as he was to dine at the Mannings, and meet friends, one a young lady. He was seen afterwards smoking and talking with his hosts in their back parlour, and never seen again alive. It came out in the husband's confession that Mrs. Manning induced O'Connor to go down to the kitchen to wash his hands, that she followed him to the basement, that she stood behind him as he stood near the open grave she herself had dug for him, and which he mistook for a drain, and that while he was speaking to her she put the muzzle of the pistol close to the back of his head and shot him down. She ran upstairs, told her husband, made him go down and look at her handiwork, and as O'Connor was not quite dead, Manning gave the coup de grâce with a crowbar. After this Mrs. Manning changed her dress and went off in a cab to O'Connor's lodgings, which, having possessed herself of the murdered man's keys, she rifled from end to end. Returning to her own home, where Manning meantime had been calmly smoking and talking to the neighbours
over the basement wall, the corpse lying just inside the kitchen all the while, the two set to work to strip the body and hide it under the stones of the floor. This job was not completed till the following day, as the hole had to be enlarged, and the only tool they had was a dust-shovel. A quantity of quicklime was thrown in with the body to destroy all identification. This was on a Thursday evening. For the remainder of that week and part of the next the murderers stayed in the house, and occupied the kitchen, close to the remains of their victim. On the Sunday Mrs. Manning roasted a goose at this same kitchen fire, and ate it with relish in the afternoon. This cold-blooded indifference after the event was only outdone by the premeditation of this horrible murder. The hole must have been excavated and the quicklime purchased quite three weeks before O'Connor met his death, and during that time he must frequently have stood or sat over his own grave.
Discovery of the murder came in this wise. O'Connor, a punctual and well-conducted official, was at once missed at the London Docks. On the third day his friends began to inquire for him, and at their request two police officers were sent to Bermondsey to inquire for him at the Mannings, with whom it was well known that he was very intimate. The Mannings had seen or heard nothing of him, of course. As O'Connor still did not turn up, the police after a couple of days returned to
Minver Place. The house was empty, bare and stripped of all its furniture, and its former occupants had decamped. The circumstance was suspicious, and a search was at once made of the whole premises. In the back kitchen one of the detectives remarked that the cement between certain stones looked lighter than the rest, and on trying it with a knife, he found that it was soft and new, while elsewhere it was set and hard. The stones were at once taken up; beneath them was a layer of fresh mortar, beneath that a lot of loose earth, amongst which a stocking was turned up, and presently a human toe. Six inches lower the body of O'Connor was uncovered. He was lying on his face, his legs tied up to his hips so as to allow of the body fitting into the hole. The lime had done its work so rapidly that the features would have been indistinguishable but for the prominent chin and a set of false teeth.
The corpse settled all doubts, and the next point was to lay hands upon the Mannings. It was soon ascertained that the wife had gone off in a cab with a quantity of luggage. Part of this she had deposited to be left till called for at one station, while she had gone herself to another, that at Euston Square. At the first, the boxes were impounded, opened, and found to contain many of O'Connor's effects. At the second, exact information was obtained of Mrs. Manning's movements. She had gone to Edinburgh.
