What it's about
The Supreme Court ruled that prosecutors had to show a reasonable likelihood that relevant information would have been communicated to a federal officer, wiped out the Eleventh Circuit’s ruling, and sent the case back for further proceedings (vacated and remanded).
Fowler's federal witness-tampering conviction arose from the killing of Officer Christopher Horner.
The federal law at issue makes it a crime to kill someone intending to stop communication to a U.S. law-enforcement officer about a federal offense.
Question presented
To prove a criminal violation of the federal witness tampering statute when a defendant allegedly kills a witness, must the government prove that the victim would have provided information regarding a crime to a court or a law enforcement officer?
What the Court decided
Holding
In such circumstances, the Government must establish a §1512(a)(1)(C) violation by showing there was a reasonable likelihood that a relevant communication would have been made to a federal officer. 603 F. 3d 883, vacated and remanded.
