The Akkra case

Miriam de Ford has given a good deal of thought to crime and criminology of other times and spaces (see Editorial). Now she turns her talents to constructing a true crime of the future—and its solution. Herewith, then, a criminologist's lecture-report on :

Deliberate murder being so very rare a crime in our society, an account of any instance of it must attract the attention not only of criminologists but also of the general public. Very many of my auditors must remember the Akkra case well, since it occurred only last year. This, however, is the first attempt to set forth the bizarre circumstances hitherto known only to the authorities and to a few specialists.
On February 30 last, the body of a young girl was found under the Central Park mobilway in Newyork I. She had been struck on the head with some heavy object which had fractured her skull, and her auburn hair was matted with congealed blood. Two boys illegally trespassing on one of the old dirt roads in the park itself stumbled upon the corpse. She was fully dressed, but barefoot, with her socsandals lying beside her. An autopsy showed only one unusual thing—she was a virgin, though she was fully mature.
Two hundred years ago, say, this would have been a case for the homicide branch of the city police. Now, of course, there are no city police, all local law enforcement being in the hands of the Federal government, with higher supervision and appeal to the Interpol; and since there has been no reported murder (except in Africa and China, where this crime has not yet been entirely eradicated) for at least 20 years, Fedpol naturally has no specialists in homicide. Investigation therefore was up to the General Branch in Newyork Complex I.
The murderer had stupidly broken off the welded serial number disc from her wristlet—stupidly, because of course everybody's fingerprints and retinal pattern are on file with Interpol from birth. It was soon discovered that the victim was one Madolin Akkra, born in Newyork I of mixed Irish, Siamese, and Swedish descent, aged 18 years and seven months. Since it is against the law for any minor (under 25) to be gainfully employed, and there was no record of any exemption-permit, she had necessarily to be a student. She was found to be studying spaceship maintenance at Upper Newyork Combined Technicum.
