SHREVEPORT- On April 23, 2026, the United States Attorney's Office for the Western District of Louisiana charged Michael Mayence, a 54-year-old Shreveport resident, by criminal complaint with illegally possessing a firearm while being subject to a domestic violence injunction. Mayence faces up to 15 years in federal prison for the charge.

"Shamar Elkins' heinous acts have shined a bright light on the danger that domestic violence presents, and the fact that he fled to the home of a man who himself illegally possessed firearms while being subject to a domestic violence order reflects the need to deter this illegal conduct," said United States Attorney Zachary A. Keller. "This ongoing investigation shows our Office's commitment alongside our law enforcement partners to fully investigate this tragic situation."

"The Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF)'s mission is to prevent, reduce, and solve violent crime, especially firearm related violence," said ATF Special Agent in Charge Joshua Jackson. "This arrest by ATF is to prevent further risk to the public from an individual who is prohibited to have firearms and demonstrated to law enforcement, through the ongoing mass shooting investigation, as a continued threat to public safety."

After committing a mass shooting on April 19, 2026, Shamar Elkins fled from law enforcement to his associate Mayence's home in Bossier Parish. After the scene was made safe, law enforcement executed a search warrant on Mayence's home, which revealed that several firearms were inside the home. A review of Mayence's criminal history revealed that he had been subject to an active domestic violence protection order since October 2024, with the order having been served on Mayence in December 2024 and lasting until May 2026, all of which prohibits him from possessing firearms under federal law.

U.S. Attorney Zachary A. Keller for the Western District of Louisiana made the announcement.

ATF investigated this case alongside the Louisiana State Police, Shreveport Police Department, and the Federal Bureau of Investigation. It is being prosecuted by Assistant U.S. Attorney J. Aaron Crawford with assistance from Legal Assistant Amanda Morgan.

A criminal complaint is merely an allegation. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
