FBI profiling
Investigative technique used by FBI behavioral analysts to infer characteristics of unknown offenders from crime scene evidence, victimology, and behavioral patterns. Not defined in federal criminal code but used as investigative tool to generate leads.

Definition
FBI profiling, more formally known as criminal investigative analysis, is an investigative technique employed by FBI behavioral analysts to infer characteristics of unknown offenders by examining crime scene evidence, victimology, and behavioral patterns. The practice involves evaluating and interpreting a suspect's actions and behavior to assist criminal investigations, primarily to generate investigative leads rather than to prove guilt.
The term itself is not defined in the U.S. federal criminal code and does not exist as a legal term of art in federal criminal law. Instead, FBI profiling operates as part of the Bureau's general federal law enforcement authority under its investigative function. The FBI's Behavioral Analysis Unit conducts this work as a specialized investigative service, though no specific statute codifies or regulates the practice by that name.
In practice, FBI profiling is used to help investigators understand offender motivation, predict likely behavior, and identify possible links between cases. The technique may assist in narrowing suspect pools, determining investigative priorities, and developing interview strategies. However, profiling results are considered investigative tools rather than evidence admissible on their own to establish guilt in court.
The methodology draws on behavioral science, forensic psychology, and case experience to develop hypotheses about unknown subjects. Analysts examine factors such as crime scene characteristics, victim selection, method of approach, and post-offense behavior to construct likely offender profiles. These profiles may suggest demographic characteristics, personality traits, behavioral patterns, or other investigative leads that can focus investigative resources more effectively.
