At St. Louis County jury on Monday acquitted Daniel Hughes on three counts of child molestation and one of sodomy.
Hughes, of Conshohocken, Pa., told police that a clerk at the Ritz-Carlton in Clayton gave him the wrong room key in March 2011 and he ended up in bed with the girl.
The girl testified that Hughes touched her inappropriately. Her parents found Hughes standing in the room in his underwear.
The St. Louis Post Dispatch reports Hughes told police he thought the person in the bed was a woman he met while drinking earlier in the night.
