When Does the FBI Investigate Murder?

In November 2020, I was invited to be on Podcast Row at CrimeCon House Arrest. During the event, I met dozens of true crime fans who stopped by my virtual booth to chat about FBI Retired Case File Review. Because CrimeCon focuses on the victims of violent crime and missing person and murder investigations, the number one question I was asked was when can the FBI be called in to take over a stalled or botched local homicide case. I explained that unless the local police department requests behavioral analysis or FBI Laboratory assistance, the FBI has no authority to interfere in a local murder investigation. However, there are circumstances where murder is a violation of federal law and agents work closely with local and state first responders, police departments, and medical examiners on a homicide.

Even in these situations, the presence of a corpse is usually not the primary felony the agents are investigating.

Here’s a quick list of federal jurisdictions related to murder:

  • A local or state police department requests that the FBI file for an Unlawful Flight to Avoid Prosecution (UFAP) warrant to allow the Bureau to enter a local homicide case. The Bureau’s task is the apprehension of the interstate fugitive, not the investigation of the actual murder.
  • A homicide occurs on federal property, an Indian reservation, or is committed by a civilian onboard a US Navy or US Merchant Marine ship in international waters, or is committed by a civilian on US military bases worldwide.
  • Another federal violation is also in play when the victim was killed, such as a hate crime where the person’s civil rights were violated, a teller or security guard is murdered during the robbery of a federally insured bank, or a kidnapping where the victim was taken across state lines.
  • The murder victim is a US president, or other elected or appointed federal officials, such as cabinet members and members of congress.
  • The murder victim is a federal judge, a federal prosecutor, or federal law enforcement official, such as an FBI, DEA, IRS, or Secret Service agent.
  • The purpose of the murder was to promote a criminal enterprise, such as in organized crime and drug trafficking.
  • A court officer or juror was murdered in retaliation of testimony given at trial.
  • An federal informant or witness is murdered to prevent them from testifying or in retaliation for them having provided testimony.
  • The murders involve violent crimes against interstate travelers, such as serial killings.
  • The murder affects interstate commerce, such as a murder-for-hire or where the US Postal Service is used to send items to cause the death of the recipient.

    If a military person dies the military investigators are involved rarely would FBI step in unless requested by that military agency like NCIS, ACID ETC.
