Grand jury indicts Graff on charge of sexually abusing teenage girl; trial set for Sept. 12

QUINCY — An indictment has been filed against a Quincy man accused of sexually abusing a teenage girl.

Jonathan Graff, 31, was indicted July 2 by an Adams County grand jury. He appeared with attorney Drew Schnack on Wednesday morning in Adams County Circuit Court. He pled not guilty to one count of aggravated criminal sexual abuse, a Class 2 felony punishable for between three and seven years in the Illinois Department of Corrections. Graff could be fined for up to $25,000, and he also is eligible for probation.

Judge Roger Thomson set Graff’s case for a jury trial on Sept. 12, with a pre-trial hearing set for Sept. 2.

The grand jury determined Graff fondled the sex organ of a girl, who was at least 13 years old but under 17 years old, through her clothing on May 12 for the purpose of his sexual arousal or gratification. Graff was arrested May 19.

The Quincy Police Department confirmed officers investigated a possible inappropriate relationship between Graff and a 16-year-old Quincy girl, who was interviewed and provided details and other corroborating evidence.

Graff was an assistant coach on the girls basketball team at Quincy Notre Dame, a youth boys and girls basketball coach for a local AAU team and an employee of TAP (Total Athlete Performance). He remains in the Adams County Jail on $100,000 bond.
