Former Big Rock lay pastor sentenced to additional 6 years for criminal sexual assault

Kane prosecutor: Victim was intoxicated and unable to give consent

Mark Rivera, 49, of the zero to 100 block of East Street, Winfield, was found guilty of two counts of predatory criminal sexual assault of a child and three counts of aggravated criminal sexual abuse.

ST. CHARLES TOWNSHIP – A former Big Rock lay pastor, already sentenced to 15 years in prison last month for sexually assaulting a child, will serve an additional six years for criminal sexual assault in a separate case, the Kane County State’s Attorney announced in a news release.

Mark Rivera, 49, of the 0-100 block of East Street, Winfield must serve 85% of the 21 years to which he has been sentenced, according to Illinois law.

In a complaint filed Dec. 29. 2021, Rivera had been charged with four counts of felony criminal sexual assault of a victim who was unable to give consent, court records show.

Kane County Circuit Judge John Barsanti accepted his guilty plea to one count on April 12.

Assistant State’s Attorney Matthew Rodgers stated in court that, on the night of Feb. 16, 2018, the victim and others were at Rivera’s home on Granart Road in unincorporated Big Rock Township.

The victim and Rivera had known one another for several years.

The victim became intoxicated and Rivera eventually walked her home. He returned to his home and discovered that the victim had left her mobile phone there. Rivera went back with her phone and sexually assaulted her.

The defendant took advantage of the victim who was unable to consent to the act at the time because she was intoxicated, the release stated.

The six-year sentence is to be served consecutively to the 15-year sentence Rivera was given following a recent bench trial conviction of two counts of predatory criminal sexual assault of a child and three counts of aggravated criminal sexual abuse of a child under 13 years old.

In addition to the prison term, Rivera must register for life as a sexual offender in accordance with the Illinois Sexual Offender Registration Act.

“Mr. Rivera is a sexual predator who seeks out the vulnerable,” Rodgers stated in the release. “He belongs in prison. I wish to express my gratitude to his victims for speaking up and preventing him from preying on anyone else. Thanks to the Kane County Sheriff’s Office staff for their work in this investigation.”
