The Roane County grand jury returned a superseding indictment last week in a sex crime case.
Jack Martin Hornbeck was originally indicted last year on one count of attempted aggravated rape when he was 17.
Hornbeck is now 18 and the new indictment charges him and another 18-year-old, Houstin Layne Longmire.
Hornbeck is charged with attempted aggravated rape, aggravated rape, attempted rape, and facilitation of rape. Longmire is charged with attempted aggravated rape, aggravated rape and rape.
The crimes allegedly occurred on Oct. 3, 2015.
