No. The U.S. Attorney’s Office is not an investigative law enforcement agency. Crimes are generally investigated by investigative law enforcement agencies, such as the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), Customs and Border Protection (CBP), the Drug Enforcement Administration (DEA), the Department of Homeland Security (DHS) and Immigration and Customs Enforcement (ICE), the Federal Bureau of Investigation (FBI), and tribal, state, and local police agencies. The U.S. Attorney’s Office reviews and considers reports, documents, and other evidence collected, analyzed, and referred to us by investigative law enforcement agencies.  Public requests for investigation must be made with investigative law enforcement agencies like those linked here.

The U.S. Attorney’s Office in Arizona prosecutes federal crimes committed within the state of Arizona, also referred to as the District of Arizona. Some examples are: bank robbery; financial crimes such as, financial fraud, wire fraud, mail fraud, and federal tax fraud; public corruption; civil rights crimes; National Security, Border Security, and Terrorism crimes; crimes committed on any of the 22 federally recognized Indian Reservations in Arizona; sex trafficking; child pornography; environmental crimes; immigration offenses;  firearms offenses; and controlled substance offenses.
