On December 13, 1990, police discovered the body of a woman dumped on a street in the Oak Cliff neighborhood in Dallas. Clad only in a T-shirt, the woman had been shot in the back of the head. The victim was Mary Lou Pratt, 33, a known prostitute who worked in the Oak Cliff area.
Police considered the case routine until the medical examiner did the autopsy. When Dr. Elizabeth Peacock opened one eyelid, she found that the eyeball had been removed with surgical precision. The killer had removed both eyeballs and taken them with him.
