When one commits the crime of murder in a single state of the United States, does he also violate a federal law against murder, or does it only become a federal crime if the murderer crosses state lines and commits murder in multiple states?

1 Answer 1


Many of the federal laws against murder involve the murder of a federal official, such as the President or a postal worker. In those cases, the murder is both a state offense and a federal offense.

There are also other federal murder offenses that do not involve interstate activity.

  • "There are also other federal murder offenses that do not involve interstate activity." Could you please elaborate on that? That's what I'm interested in (not murdering federal officials).

    @Geremia There are more examples at greenspunlaw.com/library/…. such as a murder committed to try to influence the outcome of a federal court case, a murder committed during a bank robbery, a murder related to rape, child molestation, or the sexual exploitation of children, drug-related murders, murders by mail, and terrorism related murders (as well as murders on Indian reservations, as noted).

    Murders committed on military bases or inside the buildings of federal agencies.

    @nick012000 For the same reason, murders committed in federal parks or on any federal land, of which there is a lot.
