A federal grand jury has indicted the alleged gunmen suspected of killing a 24-year-old man and wounding nine others during Mobile’s New Year’s Eve celebration on two gun-related charges.

Thomas Thomas Jr. was indicted Wednesday by a grand jury in federal court in Mobile of illegal possession of a machine gun and and possession of an unregistered firearm, court records showed.

Federal prosecutors alleged Thomas used a so-called “Glock switch,” a device that transforms a handgun into a machine gun.

Thomas is also facing state charges in connection with the shooting that killed 24-year-old Jatarious Reives and injured nine others as thousands of revelers were gathered for the city’s MoonPie Over Mobile festivities on New Year’s Eve.

Thomas is charged in state court with murder, assault first degree, shooting into an occupied building and shooting into an unoccupied building.
