Sex Predator Gets 40-Year Prison Term

The following information is from the Kane County State's Attorney's Office:

A South Elgin man, who last year was sent to prison for possessing multiple images of child pornography, today was given an additional prison sentence for sexually preying on and assaulting a young girl he knew.

William S. Muth, 46 (d.o.b. 3-3-1966), of the 1400 block of Blackhawk Circle, South Elgin, was sentenced today by Circuit Judge David R. Akemann to 40 years in the Illinois Department of Corrections.

Muth was convicted June 20, 2012, by a Kane County jury, of six counts of predatory criminal sexual assault, each a Class X felony, and two counts of aggravated criminal sexual assault, each a Class two felony.

Between Jan. 1, 2007, and Feb. 7, 2008, Muth had sexual contact multiple times with a young girl he knew. The victim was younger than 13 at the time.

The sentence breaks down as six years for each of the predatory criminal sexual assault charges, to be served consecutive to one another for a total of 36 years, and four years for each of the aggravated criminal sexual assault charges to be served concurrent to one another for a total of four years. The 36-year term and the four- year term are to be served consecutive to one another.

Muth must serve at least 85 percent of the 36-year term, and he was eligible for day- for-day credit on the four-year term.

On April 15, 2011, Muth was sentenced in Kane County court to three years in prison for his October 2010 conviction of 22 counts of possession of child pornography, each a Class 3 felony. The sentenced issued today will begin when Muth has completed the sentence for the child pornography.

The case was investigated by the Kane County Child Advocacy Center and the South Elgin Police Department. The case was prosecuted by Kane County Assistant State’s Attorneys Christine Bayer and Bill Engerman.
