Nathan H. Rigg, 35, of Woodstock.

A Woodstock man is facing decades in prison after he was convicted at trial of sexually assaulting a child in Woodstock in 2019.

Nathan H. Rigg, 35, of the 200 block of North Tryon Street in Woodstock, was indicted on charges of three counts of predatory criminal sexual assault of a child, a Class X felony, and one count of aggravated criminal sexual abuse of a child, a Class 2 felony.

Court documents alleged that Rigg sexually abused a family member, who was under the age of 13, on at least three occasions in 2019.

Rigg was arrested in March 2020 on a warrant and was released from the McHenry County Jail after posting 10% of a $50,000 bond.

A bench trial in front of McHenry County Judge Michael Coppedge took place on February 10.

On February 18, Coppedge found Rigg guilty on two counts of predatory criminal sexual assault of a child, a Class X felony.

A sentencing hearing has been scheduled for April 14.

The case was investigated by members of the Woodstock Police Department and prosecuted by Tyler Mikan and Ashur Youash of the McHenry County State’s Attorney’s Office.
