Michael Mayence, a 54-year-old resident of Shreveport, was charged on April 23 by the United States Attorney’s Office for the Western District of Louisiana with illegally possessing firearms while being subject to a domestic violence injunction. Mayence could face up to 15 years in federal prison if convicted.
The case is connected to an ongoing investigation following a mass shooting committed by Shamar Elkins on April 19. After the incident, Elkins fled law enforcement and went to Mayence’s home in Bossier Parish. Law enforcement executed a search warrant at the residence and found several firearms inside. A review of records showed that Mayence had been under an active domestic violence protection order since October 2024, which prohibits him from possessing firearms under federal law.
"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."
ATF Special Agent in Charge Joshua Jackson said, "The Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF)’s mission is to prevent, reduce, and solve violent crime, especially firearm related violence. 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."
The case was investigated by ATF together with Louisiana State Police, Shreveport Police Department, and Federal Bureau of Investigation. Assistant U.S. Attorney J. Aaron Crawford is prosecuting with assistance from Legal Assistant Amanda Morgan.
Officials emphasized that criminal complaints are only allegations and all defendants are presumed innocent until proven guilty beyond reasonable doubt in court.
