ABSTRACT
Investigators cannot solve crimes without accurate information. Sources of information are innumerable. Criminal investigators must become familiar with those that will be most bene–cial in the speci–c type of o¡ense they are investigating. What is a burglary investigator’s best source of information? What are the best sources for investigating a missing child? What sources does a drug investigator use to make a case? A good investigator must develop the skills for obtaining information. Law enforcement agencies should train their investigators in developing sources of information and preparing information documents for their agencies.
