About the Author
Gregg McCrary is one of the world's most experienced profilers. As a Supervisory Special Agent with the FBI's Behavioral Science Unit, he reported directly to BSU chief John Douglas, and with other experts, developed the Crime Classification Manual, a system for standardizing violent crimes into categories. Since retiring from the FBI in 1995, he has taught forensic psychology at Marymount University and Nova Southeastern University. McCrary continues to consult and provide expert testimony in cases in which crime scene analysis is key, and provides expert commentary to NBC, ABC, CBS, and CNN.
