COLUMBIA, SC (WIS) - The lone suspect in the disappearance of 15-year-old Gabrielle Swainson is appealing a federal ammo conviction that promises to lock him up for more than 17 years.
Last week Grant, 53, was convicted of possession of ammunition by an individual who is disqualified to do so because of a prior conviction.
A federal judge handed down a sentence of 212 months in prison.
Grant's attorney on Monday filed the notice of appeal to the United States Court of Appeals for the Fourth Circuit.
Investigators found a box of shotgun shells and a box of .38 caliber bullets in Grant's home while they were searching for clues in Swainson's disappearance.
Swainson remains missing after 8 months.
Richland County investigators plan to bring Grant back to court again any day now to face a kidnapping charge.
"We could go to court today," said Richland County Sheriff Leon Lott last week. "We're ready. We're prepared. The forensics are in, our leads have been followed up, we've done all the work, so we're ready to go, but we don't have to go right now, and that's the key."
Thursday's verdict appears to give investigators more time to look into and follow up on leads in the case.
