Jacksonville, Florida – Matthew Reid Davisson, 36, of Jacksonville, was sentenced to four years and five months in federal prison for possession of unregistered destructive devices, U.S. District Judge Marcia Morales Howard announced. Davisson had previously pleaded guilty on February 18, 2025.
According to court documents, Davisson was initially arrested on unrelated state charges on October 26, 2023. During the investigation, the Jacksonville Sheriff’s Office and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) obtained a search warrant for his residence, where they discovered a significant cache of explosives and related materials. Law enforcement recovered two improvised explosive bombs, one improvised explosive grenade, and combinations of parts capable of assembling three additional grenades. Investigators also found large quantities of homemade high explosives, detonators, explosive precursor chemicals, and homemade manufacturing equipment.
None of the devices were registered with the National Firearms Registration and Transfer Record, as required by federal law. In addition, a family member surrendered a firearm to authorities that was later determined to be an unregistered machine gun with an attached homemade silencer.
This case was investigated by the ATF, the Federal Bureau of Investigation, and the Jacksonville Sheriff’s Office. It was prosecuted by Assistant United States Attorneys David B. Mesrobian and Rachel Lasry.
The sentence reflects the seriousness of possessing unregistered explosives and destructive devices and the potential threat such materials pose to public safety.
