Lecture NotesLesson 4:Chapter 7 Developing Investigative Leads and IntelligenceChapter 8 Investigation and The Forensic Sciences An investigative lead is information that may be useful in an investigation. Criminal intelligence is information from leads or other sources which has been analyzed to provide specific knowledge. Both leads and criminal intelligence are useful in the follow-up investigation process.Many agencies use some sort of checklist to make sure that all of the steps in the process are covered. One of the first steps is to search the various databases for information. The National Crime Information Center (NCIC) contains vast amounts of data in 19 files that include 7 persons files and 12 property files. Wanted or known criminals, sex offenders, stolen property, and other files are searched by law enforcement agencies for information. Additionally, state and local records contain a lot of information that can be searched for leads. There is a wealth of information available on people in both private-sector and government-agency files that can be legally accessed during a criminal investigation. These sources save many man-hours that would have been spent generating information that is already available.
