SHREVEPORT– On May 21, 2026, Alvieyle Moore, a 40-year-old inmate at the Jackson Parish Jail, was sentenced to the statutory maximum of 60 months in federal prison after pleading guilty to perpetrating a hoax relating to purported chemical weapons directed at the United States Supreme Court. In addition to his prison sentence, Moore will serve three years of supervised release following his release from federal prison.
According to court documents, Moore mailed a threatening letter to the Supreme Court of the United States that falsely claimed to be laced with fentanyl that would kill its reader. The letter, which contained approximately one tablespoon of a white, powdery substance and stated, “IF You Are Reading this you are gonna die soon because this letter is laced with Fentanyl!!”, caused the evacuation of the Supreme Court’s warehouse facility and prompted a hazardous materials team response.
The Supreme Court of the United States Police - Protective Intelligence Unit, United States Secret Service, and Federal Bureau of Investigation investigated this case. It is being prosecuted by Assistant U.S. Attorney Seth D. Reeg with assistance from Paralegal Specialist Ginger Green.
U.S. Attorney Zachary A. Keller for the Western District of Louisiana made the announcement.
