About ten minutes to five o'clock on the morning following Bank Holiday, John Reeves, who lives at 37, George-yard-buildings, Whitechapel, was coming downstairs to go to work, when he discovered the body of a woman lying in a pool of blood on the first-floor landing. Reeves at once called in Constable Barrett, 26 H, who was on his beat in the vicinity of George-yard, and Dr. Keeling, of Brick-lane, was communicated with and promptly arrived. He made an examination of the woman, and pronounced life extinct, giving it as his opinion that she had been brutally murdered, there being knife-wounds on her breast, stomach, and abdomen. It is stated that there were 24 wounds in various parts of the body, which was that of a woman apparently between 35 and 40 years of age, about 5 ft. 3 in. in height, complexion and hair dark, wore a dark-green skirt, a brown petticoat, a long black jacket, and a black bonnet. The woman is unknown to any of the occupants of the tenements on the landing on which the deceased was found, and no disturbance of any kind was heard during the night. There circumstances of the tragedy are, therefore, mysterious, and the body was removed to Whitechapel Mortuary; and Inspector Elliston, of the Commercial-street Police-station, placed the case in the hands of Inspector Reid, of the Criminal Investigation Department.
