BOSTON -- The aunt of a child who was accidentally shot to death earlier this year was arraigned Wednesday on gun possession and drug trafficking charges in a case unrelated to the boy's fatal shooting.

Antonia Gadson, 28, of Dorchester, was charged in Suffolk Superior Court with two counts of unlawful possession of a firearm in her Blue Hill Avenue apartment and one count each of unlawfully carrying a firearm, unlawful possession of ammunition, trafficking in more than 100 grams of cocaine in a school zone and possession of a class B substance.

Gadson was the aunt of 8-year-old Liquarry Jefferson, who was shot to death in his mother's Seaver Street home on June 24.

Superior Court Clerk Magistrate Gary D. Wilson set bail at $15,000 and ordered Gadson to return to court on Nov. 28 for a pretrial conference.

The charges against Gadson stem from the May 30, 2006, homicide of Dwayne Turnbow who was killed next to his car a short distance from Gadson's residence. Police said that shortly after his death, she retrieved a .38 caliber revolver from his car and brought it into her home.

Officials said that they found the gun, a second firearm, a quantity of ammunition for firearms of various calibers, 54 Ecstasy tablets and a large quantity of cocaine in powder and crack forms at Gadson's home.
