These are the remains of Mary Jane Kelly, the fifth canonical victim of Jack the Ripper. Her mutilations were far more extensive than the others’, perhaps because she was the only victim killed in a private room. From the notes of police surgeon Thomas Bond:

“The whole of the surface of the abdomen and thighs was removed and the abdominal cavity emptied of its viscera. The breasts were cut off, the arms mutilated by several jagged wounds and the face hacked beyond recognition of the features. The tissues of the neck were severed all round down to the bone.

“The viscera were found in various parts viz: the uterus and kidneys with one breast under the head, the other breast by the right foot, the liver between the feet, the intestines by the right side and the spleen by the left side of the body. The flaps removed from the abdomen and thighs were on a table.”

She was last seen alive at 2 a.m. on Nov. 9, 1888, in the company of a “Jewish-looking man” as they walked to her room. Her fellow prostitute Mary Ann Cox, unable to sleep, heard someone leave the house at 5:45. In between, at about 4 a.m., two neighbors heard a faint woman’s voice cry “Murder!”
