COLUMBIA, S.C. (AP) -- A man accused of abducting a Columbia teen last seen more than two months ago is expected in court on a federal ammunition charge.

Records show Freddie Grant is scheduled to appear in federal court in Columbia on Tuesday.

Earlier this month, Grant pleaded not guilty to being a felon in possession of ammunition.

Gabrielle Swainson was last seen by her mother at around 4 a.m. on August 18. That month, Grant was charged with kidnapping the missing teen after her blood was found on duct tape near his home.

Authorities also found .38-caliber bullets and shells for a 12-gauge shotgun -- ammunition Grant isn't allowed to have as a convicted felon.

Authorities have said Grant had dated the 15-year-old's mother and did yard work for the family.
