As may be imagined, the whole neighbourhood was in an uproar of confusion at this most extraordinary circumstance; and information was immediately conveyed to the coroner, in order that an inquest might be held. By the time a coroner's jury had assembled, a surgical examination of the body had taken place; and Mr. John Lawden, a surgeon, proved, that there were appearances yet remaining sufficient to indicate that the deceased had come to her death by violent means. He said that there was a visible appearance of blood on the face and on the clothes of the deceased, and also on a handkerchief which was round the neck; that the handkerchief appeared to have been tied extremely tight, and beneath the folds, a wound was visible in the throat, which had evidently been inflicted by some sharp instrument. There was also a wound in the orbit of the right eye; and it seemed as if something had been thrust in which had fractured the small bones, and penetrated the brain. On the finding of the body, it was partly enveloped in a sack, and it was clothed only in a shift, flannel petticoat, stays, stockings, and shoes.
No sooner had the body been discovered than all eyes turned to Corder as the murderer; and information having been despatched to London, Lea, an officer of Lambeth-street, was forthwith sent in pursuit of the supposed offender. With a loose clue only he traced him from place to place, until at length he found him residing at Grove House, Ealing-lane, near Brentford, where, in conjunction with his wife, whom he had married only about five months before, and to whom, it was said, he had introduced himself through the medium of a matrimonial advertisement, he was carrying on a school for young ladies. It was necessary to employ a degree of stratagem to obtain admission to the house; but at length, Lea, having represented that he had a daughter, whom he wished to put to school, he was introduced to a parlour, where he found the object of his search sitting at breakfast with four ladies. He was in his dressing-gown, and he had his watch before him, with which he was minuting the boiling of some eggs. The officer having called him on one side, informed him that he had a serious charge against him, and inquired whether he was not acquainted with a person named Maria Marten at Polstead; but he denied that he had any knowledge of such a person even by name. He was then secured; and upon his house being searched, a brace of pistols, a powder-flask, and some balls, were found in a velvet bag, which on its being subsequently seen by Mrs. Marten, was immediately identified by her as having been in the possession of her daughter at the time of her quitting her house for the last time. A sharp-pointed dagger was also found, and this was identified by a person named Offord, a cutler, as being one which he had ground for the prisoner within a few days before the murder was committed. The prisoner immediately on his apprehension was conducted to Polstead, in order that he might undergo an examination before the coroner; and the most lively interest was exhibited by the vast crowds of people who had assembled, to catch a glimpse of him on his being brought into the town. On his appearance before the coroner, he was dreadfully agitated; and the circumstances which we have described having been deposed to by various witnesses, a verdict of "Wilful Murder" was returned against William Corder.
