FBI Linguistics Manhunt for the Unabomber, Christopher Dorner&DC Sniper

Evidence gathered from letters and manifestos left by criminals isn't limited to pulling fingerprints and DNA. The content and linguistics are studied and analyzed by the FBI, as our guest James Fitzgerald shares his experience in the Unabomber, DC Sniper, Jon Benet cases and more on Crime Time. By marking language traits and even intentional misspellings, we see the FBI's methods of assessing guilt from suspect's writings.

GUEST BIO:
James R. Fitzgerald was the Program Manager of Threat Assessment/Forensic Linguistics at the Behavioral Analysis Unit 1 of the FBI.
In 1995, Fitzgerald became a profiler at the FBI Academy at Quantico, Va. As part of Fitzgerald's profiler training, he learned about analyzing communications. He later obtained a Master's degree in linguistics from Georgetown University. (This was his second MS. His first was in Organizational Psychology at Villanova University.) As he has at his present company, The Academy Group, Fitzgerald created a linguistic-oriented database of threatening and/or suspicious letters, similar to one the Secret Service maintains.
Fitzgerald was assigned to the Unabomb investigation in San Francisco. His findings helped narrow the investigation to Kaczynski. His 50-page probable cause affidavit, the first of its kind in federal court using text analysis, was the primary factor behind the judge signing the search warrant for Kaczynski's cabin. Fitzgerald worked other high-profile cases like those of Danny Pearl, Jon Benet Ramsey, and the D.C. sniper.
Fitzgerald now works for the Academy Group in Manassas, Va., which provides profiling services for private industry as well as a university instructor, author, and technical advisor for television programs (Criminal Minds) involving the Federal Bureau of Investigation.
