Coincident with the discovery of this evidence, the voluntary testimony of two other witnesses was obtained, which afforded conclusive proof of the violent means resorted to by Burke and Hare, to procure the death of the deceased. Mr. and Mrs. Gray, poor persons, who were travelling through Edinburgh, informed the police, on the same day, of occurrences which they had witnessed on the night of the 31st October, which induced the most dreadful suspicions in their minds. They stated that they had taken up their lodgings in the house occupied by Burke in the course of that day, and towards the evening they had seen Mrs. Campbell go in with that person. They, however, retired to rest without holding any communication with her, as she appeared to be intoxicated; but in the morning, they were surprised to find that she was gone. They inquired of Mrs. Burke what had become of her, and she said that they had turned her out because she was impudent; but an undefinable apprehension lurked in their minds of some wrong having been done, and seizing an opportunity they peered into Burke's room, and there, under the table, they saw marks of blood, and upon further investigation, the body of the murdered woman concealed beneath some straw. Terror-struck with the discovery, they immediately gathered up their bundles and proceeded to quit the house, but were dissuaded from their intention by Mrs. Burke, who had ascertained the fact of their having made so important a discovery, who urged them to stop, "as it might be 10_l._ a week to them." They, however, rushed from the place as soon as they could escape, and on the following day conveyed intelligence to the police of what they had seen.
