Kane County State’s Attorney Jamie Mosser and Kane County Sheriff Ron Hain announce that Arthur D. Weathers is charged with the offenses of: Criminal Sexual Assault, Class 1 felony (11 counts); and Aggravated Criminal Sexual Abuse, Class 2 felony (14 counts).

Mosser alleges that between 1999 and 2001, Arthur Weathers sexually abused a minor over whom he held a position of authority. Weathers was the victim’s volleyball coach at First Kill volleyball club out of Elgin, Illinois. Weathers served in the capacity of both an assistant coach and head coach for First Kill during the years of 1999 through 2003. It is alleged that the victim was 16-years-old when the abuse began. The Kane County Sheriff’s Office initiated the investigation in August 2025 after the victim reported the allegations to law enforcement.

According to the investigation, Weathers is employed as a forensic chemist with the Illinois State Police Division of Forensic Services, where he has worked since 1998.

Weathers was arrested on the evening of May 19, 2026, and taken into the custody of the Kane County Sheriff’s Office. He appeared in court on May 20, 2026, for a pretrial detention hearing during which the State argued for his detention. The court ordered Weathers released under certain conditions while his case is pending.

Weathers’s next court date is set for July 15, 2026.

Anyone with additional information about the defendant should contact the Kane County Sheriff’s Office at (630) 444-1103.

The charges against the defendant are not proof of guilt. The defendant is presumed innocent and is entitled to a fair trial in which it is the state’s burden to prove guilt beyond a reasonable doubt.
