A 53-year-old Joliet-area man accused of sexually abusing two pre-schoolers in 2009 is scheduled to appear in Will County court May 11 on charges of predatory criminal sexual assault, a Class X felony; criminal sexual assault of a family member, a Class 1 felony; and aggravated criminal sexual abuse of a family member, a Class 2 felony.

Sheriff’s Police said Ronald W. Randolph, of the 600 block of Oak Avenue, had contact with the children at the home of a mutual relative who was caring for the girls during the day. He is not directly related to the children.

Sheriff’s Police learned of the alleged attacks from the mother, who contacted them after her older child said Randolph had acted improperly. Specially trained investigators questioned the young children, reportedly found their accounts credible and proceeded with the investigation.

Randolph remained in the Adult Detention Facility today in lieu of $750,000 bail.
