20 year old Joshua West, of Dawsonville, is being held without bond in Cherokee County, charged with rape and aggravated child molestation.

Lieutenant Jay Baker with the Cherokee County Sheriff's office tells WSB's Bob Coxe West had met the 13 year old girl on "Yearbook.com" about 3 weeks ago.  Monday he allegedly came to her house, and they had sex:

"We were notified by school police that this had been reported to a counselor at school by the victim," Baker says."

Did he know she was underage?

"It's my understanding he made statements to detectives that he thought that she was older," Baker says, "but the bottom line is, she's not."

Baker does say West is cooperating with detectives.
