(AP) — A Mississippi man is accused of possessing two fully automatic weapons in a shootout that wounded two deputies last week.

Madison County District Attorney John Bramlett said Edgar Egbert used a “fully automatic weapon” resulting in a “barrage of gunfire” on Thursday. Sheriff’s spokesman Heath Hall confirmed the guns were “full” automatic.

The Clarion Ledger reports state and federal Bureau of Alcohol, Tobacco, Firearms and Explosives officials say the use of such weapons in the commission of a crime is extremely unusual.

Illegally possessing or using a fully automatic gun carries stiff federal penalties under The National Firearms Act. The state Bureau of Investigation is investigating.

Egbert is jailed for now on charges including kidnapping and attempted murder of law enforcement.
