Clayton Police Chief Tom Byrne says Hughes told a front desk clerk his key didn't work, so the clerk gave him a key for the room number he provided. Hughes went to the room, forced his way in and entered a bed occupied by a 9-year-old girl. Byrne says the girl alerted her parents, who were staying in another bedroom.
The St. Louis Post-Dispatch reports that Hughes is charged with child molestation and sodomy.
The hotel is conducting its own investigation.
