Criminal Investigator Job Description

A federal criminal investigator, sometimes called a special agent, investigates potential crimes against the public and the U.S. government. More than 50 federal agencies employ investigators, including the Department of Energy, U.S. Secret Service, Federal Bureau of Investigation (FBI), Internal Revenue Service (IRS), Amtrak and the U.S. Fish and Wildlife Service. Federal investigators work in all 50 states and the District of Columbia.

Most agencies require that those applying for federal investigator jobs be younger than 37, have a degree in a field related to the agency's focus and pass a background check. Some agencies, such as the National Park Service, require candidates to have prior experience working within that agency.

Qualified candidates are specially trained at a Federal Law Enforcement Training Center. There are several facilities, located in Georgia, New Mexico, South Carolina and Maryland. The basic training program for entry-level investigators lasts approximately two months and includes instruction in criminal case development, interviews, writing case reports, serving warrants, case management, handling evidence and surveillance. Physical fitness, firearm and vehicle operation training are also included.

Job Duties of an Investigator

In general, federal criminal investigators investigate potential cases, gather evidence related to criminal activity, interview witnesses, arrest people accused of crimes, and testify in court if necessary. The specific tasks investigators perform depend on the agency they work for; for example, individuals working for the Secret Service investigate financial crimes, while those employed by the Internal Revenue Service investigate tax fraud. Investigators working for the FBI investigate drug trafficking, human rights violations and organized crime.
