Columbia, SC (WLTX) - The man accused of kidnapping teenager Gabbiee Swainson was found guilty on separate federal ammunition charges Tuesday.
Meanwhile, the girl's father is expressing deep concerns about her ultimate fate.
"I don't think she's alive," said Alvin Thompson, Swainson's father. "I don't think she's alive. It's been way too much time. Only one person knows that for sure: him."
Thompson believes Freddie Grant, the man found guilty of having ammunition while being a convicted felon, also kidnapped his daughter Gabbiee.
"That still doesn't bring my daughter back to me," said Thompson. "I feel for his family, but at the same time I feel for my daughter because I don't know where she's at."
Richland County Sheriff's investigators found shotgun shells and .38-caliber bullets when they raided Grant's Elgin home in August.
Grant can not possess ammunition because he's a convicted felon.
"When we see career criminals like Mr. Grant and they're in possession of ammunition, they're probably coming to federal court no matter what the circumstances are," said Assistant U.S. Attorney Stacey Haynes.
Haynes notes while the ammunition were not on Grant's person, he can still be 'in possession' under the law.
"Constructive possession: it's all the items you have back in your house, it's the items you don't have on your body," said Hayes. "You still possess them, you're just not in actual possession. Just because we don't have them on us every day, doesn't mean we don't have dominion over them."
"I think the jury deliberated a very long time about this," said defense attorney John Delgado. "There were obviously questions in some jurors minds about if Freddie had known and intended to possess that ammunition."
Delgado says Grant will stay in the Lexington County Detention Center until he's sentenced in April.
"That was my brother," said Freddie Grant's brother Johnny Grant. "He's the only brother that I could do anything with. So, now I don't have anybody."
