The Criminal Division of the U.S. Attorney’s Office is responsible for prosecuting violations of federal criminal laws.  These offenses cover a wide range of crimes including civil rights violations, investment fraud, bank and securities fraud, health care fraud, public corruption, violent crimes committed by street gangs, major narcotics trafficking, firearms offenses, identity theft, child pornography, immigration offenses, human trafficking, tax offenses, and theft from government programs.

The Criminal Division works closely with a number of federal law enforcement agencies in the District that investigate suspected violations.  These agencies include the Federal Bureau of Investigation, Drug Enforcement Administration, Bureau of Alcohol, Tobacco, Firearms and Explosives, United States Marshal’s Service, Internal Revenue Service, United States Secret Service, United States Postal Inspection Service, Department of Health and Human Services, Environmental Protection Agency, and the Offices of Inspector General for various federal agencies.  The Criminal Division also works closely with the Tennessee Bureau of Investigation, local police departments, county sheriff’s offices, and drug task forces consisting of representatives from federal state and local law enforcement to enforce federal law.

The Criminal Division consists of a Criminal Chief, three Deputy Criminal Chiefs and approximately 18 Assistant United States Attorneys (AUSAs).  The AUSAs are assigned to one of three sections that focus on specific substantive areas of federal criminal law.

The White Collar and Economic Crime Unit prosecute a wide variety of major fraud, civil rights and corruption offenses focusing on criminal acts and schemes that significantly affect the citizens of the Middle Tennessee area.  The investigations and prosecutions frequently involve complex criminal schemes implicating the bank, mail, and wire fraud statutes.  The unit has also prosecuted numerous child pornography cases that have resulted in lengthy prison sentences for those offenders.

The Narcotics Unit identifies, investigates, and prosecutes the most significant drug trafficking and money laundering organizations with the goal of disrupting and dismantling the operations of those organizations in order to reduce the drug supply in the Middle District of Tennessee and the United States.  Many of the individuals and drug trafficking organizations this unit prosecutes have significant ties to national or international drug trafficking.   The unit also focuses on drug trafficking organizations that directly impact communities in the district.

The Firearms and Violent Crimes Unit prosecutes violent street gangs as well violations of federal firearms laws, including felons who illegally possess guns and those who illegally buy and sell firearms.  The unit solicits community and local law enforcement feedback to target violent gangs and repeat offenders responsible for murders, aggravated assaults and drive-by shootings.  These street gangs include the Gangster Disciples, MS-13, Vice Lords, Rollin 90’s, Bloods and Crips, among others.
