(CNN) A 14-year-old girl who disappeared from Tennessee more than two weeks ago has been found alive in Wisconsin and her father is now charged with rape, authorities said Thursday.

The girl is "doing fine," Sheriff Tommy Jones of Monroe County, Tennessee, said Thursday.

Randall Pruitt, who adopted the girl, was arrested Thursday in Tennessee and charged with rape, the sheriff said. "(The girl) would be the victim in that," Jones said.

The sheriff did not provide many details about the case in a news conference Thursday, but said there could be additional suspects.

"I'm having to be vague on all my statements because this is still an ongoing investigation," he said. "At this point, we are still investigating there's a possibility of multiple other charges coming forth with multiple people involved."
