A
STANDARD SYSTEM FOR INVESTIGATING AND CLASSIFYING VIOLENT CRIMES
SECOND
EDITION
Cyanide is often
the poison of choice because it is easily available at chemical and photographic
supply houses and in college and high school laboratories. It can also be
ordered through the mail. One ounce can kill 250 people, so its potency makes it
a popular choice with product tampering offenders. An important investigative tool
in cases of an offender who has used cyanide is a complex instrument in use at the
Food and Drug Administration’s Cincinnati district laboratory. It can track down
the source of the cyanide and identify the supplier, who can find the geographical
customer list rather quickly. This may help narrow the list of typical suspects
(chemical firms, grocery clerks, the enemies of deceased victims, or a store’s
terminated personnel file) and further isolate the offender.
