A jury found Timothy McWilliams guilty on first-degree child molestation charges in Boone County court Thursday.
McWilliams was arrested in December 2014 after detectives searched his home and allegedly found evidence relating to the incident.
First Assistant Prosecutor Tracy Gonzalez said the victim, now 8 years old, testified at the trial.
McWilliams was out on a pretrial release bond, but the judge ordered a new $20,000 cash-only bond following the verdict. He was taken into custody after the trial.
He could face up to eight years in prison.
