Mr. Gurney, in opening the case to the jury, stated that the deceased, Mr. William Weare, was known to be addicted to play, and to be in the habit of frequenting gaming-houses, and that the prisoner, Thurtell, was acquainted with him, and, as it was said, had been wronged by him, in respect to some play, in which they had been engaged, and had been deprived by him of a large sum of money. The prisoner, Hunt, was also known to Mr. Weare, but was not in habits of friendship or intimacy with him. He would next describe a person, whom he should have to call in evidence against the prisoners. He alluded to Probert, who was a party to the murder, after its commission, although it did not appear that he had any hand in its actual perpetration. He was engaged in trade as a spirit-dealer, and he rented a cottage in a secluded spot, called Gill's Hill Lane, situated about three miles from Elstree. He was himself usually engaged in London, in his business, during the day, and his wife lived at the cottage, which was a small one, and was fully occupied by his wife, her sister, (Miss Noyes,) some children of Thurtell's brother, Thomas, a maid-servant, and a boy. The vicinity of this cottage was selected by the prisoners as a fit spot for the perpetration of the murder, which had been already determined upon; and the mode of the commission of which, he should now proceed to describe. Thurtell and the deceased met at a billiard-room, kept by one Rexworthy, on the evening of Thursday, the 23rd of October, and being joined there by Hunt, Mr. Weare was invited by Thurtell to go to Probert's cottage, for the purpose of enjoying some shooting in the neighbourhood, for two or three days. He accepted the invitation, and the following day was fixed for him to meet Thurtell, who promised to drive him down to the place. On the forenoon of the Friday, the deceased called at Rexworthy's, saying, that he was going out shooting with Thurtell, and at about three o'clock he went home, to the chambers, which he occupied in Lyon's Inn, and having partaken of a chop dinner, he packed up some clothes in a green carpet bag, and the laundress having called a coach, he went away in it, carrying with him the carpet bag, a double barrelled gun, in a case, together with a back-gammon board, containing dice, &c. He left his chambers in this manner before four o'clock, and drove first to Charing Cross, and afterwards to Maddox-street, Hanover square; thence he proceeded to the New Road, where he got out of the coach, but returned after some time, accompanied by another person, and took his things away. At this time, Thomas and John Thurtell had need of temporary concealment, owing to their inability to provide the bail requisite to meet a charge of misdemeanour; and Probert had procured for them a retreat at Tetsall's, at the sign of the Coach and Horses, in Conduit-street, where they remained for two or three weeks previous to the murder.
