The trial judge did not err under Rule 412 in excluding evidence of the victim’s prior sexual activity with a boy named C.T. and with her boyfriend. As to the activity with C.T., the defendant failed to offer evidence that it occurred during the in camera hearing (when the victim denied having sex with C.T.), or at trial. Additionally, the defendant failed to establish the relevance of the sexual activity when it allegedly occurred shortly before the incidents at issue but the victim’s scarring indicated sexual activity that had occurred a month or more earlier. As to the sexual activity with the boyfriend, the defendant failed to present evidence during the in camera hearing that the activity could have caused the victim’s internal scarring.
