The evidence was deemed sufficient, and both prisoners were fully committed for trial at the Newcastle spring assizes of 1879. It is now known that certain facts, damaging to the prosecution, had been brought to the notice of the police. They had positive information that other persons had been abroad from Alnwick that night; they had received a statement, made with much force by one who had good reason to know, that the wrong men had been arrested; while there were witnesses who had met the prisoners soon after the burglary on the other side of Alnwick. On the other hand, fresh evidence against them was forthcoming at the trial. This was the discovery of a piece of fustian cloth with a button attached, which had been picked up by a zealous police-officer under the drawing-room window, a month after the burglary. Here again was damaging evidence, for this scrap of cloth was found to fit exactly into a gap in Brannagan's trousers. It was said afterwards, at the trial of the police, that they had purposely cut out the piece; and it was proved in evidence that a tailor of Alnwick, to whom the trousers and piece were submitted, expressed his doubts that the accident could have happened in jumping out of the window. The tear would have been more irregular, the fitting-in less exact. Moreover, the piece of cloth was perfectly fresh and clean when found, whereas, if it had lain out for nearly a month in the mud and snow, it must have become dark and dirty, and hard at the edges, as corduroy goes when exposed to the weather. As, however, the judge would not allow the cloth and button to be put in evidence, they played no important part in the case until the subsequent prosecution of the police, except possibly in prejudicing the minds of the jury against Brannagan and Murphy.
