In an article about the kidnap and killing of Marian Parker by Hickman:
The fact that Hickman named one Andrew Cramer as the murderer of Marian Parker and the fact that the girl's body was mutilated and dismembered, were connected and given significance today by Milton Carlson, handwriting and expert criminologist.
Carlson pointed out that the youthful kidnapper of the slain girl admitted familiarity with the details of the life of Jesse James and the Loeb Leopold case. He suggested that possibly Hickman also had read of the Whitechapel murders in London in 1888. Several women were murdered and mutilated and the suspected murderer, a young student of surgery, although never caught, was found dead in the Thames river. His name was Andrew Kramer.
The criminologist declared it a trait of the criminal mind to unhesitatingly use an incident or name out of a case or report of which he had read much.
