WHEATON, Ill. (CBS) – A 90-year-old Roselle man accused of sexually assaulting two children in 2007 has been sentenced to six years in prison after pleading guilty in the case, prosecutors announced Friday.

Chester Stabrowski, of 495 W. Maple, entered a guilty plea to a single count of predatory criminal sexual assault of a child, DuPage County State’s Attorney Robert B. Berlin said in a news release.

The charge stems from a 2007 incident in which Stabrowski invited two minors to his residence for a pool party and later sexually assaulted them, Berlin said. The prosecutor says Stabrowski met his young victims through volunteer work at St. Walter’s Parish in Roselle.  Berlin tells WBBM’s Bob Roberts the two victims were boys aged 11 and 13.

“The two victims still suffer the trauma and stigma of that attack, and they will be dealing with this for the rest of their lives,” he said.

Judge George Bakalis has sentenced Stabrowski to six years in the plea deal. Sentencing laws require Stabrowski to serve 85 percent of his sentence. But because he had been under house arrest since 2008, when he was first charged, he will get credit for time served.

Despite that, Berlin said, Stabrowski must serve 40 months in prison.

Stabrowski will be one of the oldest inmates in the Illinois prisons system.  Prisoners in their 80s and older are generally confined to a geriatric hospital unit at the Dixon Correctional Center, 100 miles west of Chicago.

Berlin said investigators received full cooperation from St. Walter’s Roman Catholic Church, where Stabrowski volunteered, and from the Diocese of Joliet.    

At sentencing, prosecutors said they had also developed information indicating that Stabrowski once molested a young girl. Berlin said no charges are contemplated in that case.
