Saturday 17 Aug 1844 (p. 3, col. 1) SENTENCE OF DEATH.-Mark SHERWOOD, who was tried at the Newcastle Assizes, last week, for the wilful murder of his wife, in March last, was found guilty, and sentenced to be hanged. The particulars of the case appeared in our paper at the time of its occurrence. MYSTERIOUS CASE OF MURDER.-A most cruel and horrid murder was perpetrated at High Eighton, in the county of Durham, on Saturday last. It appears that a potatoe field, belonging to Mrs. MITCALFE, of High Eighton, had suffered severely from depredators of late, and Mr. FLECK, manager of the farm, placed a watch to prevent the recurrence of these losses. On Saturday night last, he had sent a young man named YARROW to watch; and he in company with two other men, had proceeded to the brakehouse of one of the pits of Ravensworth colliery. YARROW, far as we can learn, had staid in the brakehouse till the brakesmen, Thomas ROBSON, and J. JEFFERSON, had gone to see that all was right. While they were proceeding along the top of the field, JEFFERSON observed somebody in the hedge, but went on without speaking; the brakesman also observed one, and called out "hollo," upon which the villain instantly fired a pistol at him, and he staggered a few yards and fell dead. His comrade was so paralyzed by the dreadful deed as to be completely deprived of his faculties, and he also fell, and remained in a state of stupor for a considerable time. At length Mr. FLECK came to the spot, and found them as described. ROBSON was quite dead, his heart having been partly blown out of its place, and his breast dreadfully shattered.-On Monday an inquest was held before J. M. FAVELL, Esq., county coroner, and a most respectable jury, at a farm-house on the Team Colliery, where the deceased had held the situation of a brakesman. The testimony of the youth JEFFERSON, Mr. FLECK, and Mr. DAVIS, a surgeon, were taken but the result of the examination only left this cold-blooded murder involved in still deeper mystery. Mr. DAVIS, the surgeon, and another medical gentleman took a post mortem examination of the deceased. The apex of the heart was shattered, and no fewer than 187 shots were found in his body, the greater part of them being in the back part of chest, and many of them were flattened by coming in contact with the ribs. The Coroner said that no time had yet been allowed to the police to make any inquiry into the circumstances, and therefore he would adjourn the inquest till Friday morning at 10 o'clock, in order that more information might be procured.
