JEFFERSON COUNTY — A 42-year-old Mt. Vernon man pleaded guilty Monday in Jefferson County Court to two felony counts of criminal sexual assault in exchange for more than a dozen counts of child pornography being dismissed.

Shawn Wilson was sentenced to 5-years in prison on each count to be served consecutively, for a total of 10 years in the Illinois Department of Corrections.

Wilson, who was already a registered sexual offender at the time of his February arrest, was charged with two Class 1 felony counts sexual assault and 15 counts Class 1 felony child pornography, for allegedly assaulting a girl between the ages of 13 and 18 in February 2015 and taking nude photos of her.

A warrant was issued for Wilson’s arrest on the charges in January, but he remained at large until his arrest this February in St. Clair County. He was ultimately transported to the Jefferson County Jail where he has remained with bail set at $250,000.

Wilson was first entered into the Sex Offender Registry for misdemeanor convictions in two separate Jefferson County cases for sexual exploitation of a child through a sex act.

He was subsequently arrested and convicted in 2004 and 2005 in Jefferson County for multiple misdemeanor counts of public indecency and lewd exposure.

Wilson was given credit for 201 days served in the Jefferson County Jail. His case was scheduled to go to trial Tuesday.
