A Quad Cities man found guilty in a 2019 Mercer County child sex assault case. 36-year-old Antonio Cortez Williamson will be sentenced June 13. His bench trial began in late February, resumed in early March, and then resumed again Monday, where the guilty verdict was rendered on three Class X felony counts of predatory criminal sexual assault of a child says Mercer County State’s Attorney Grace Simpson.
The Davenport man was arrested in August of 2019 following an investigation by the New Boston Police Department with assistance from the Mercer County Sheriff’s Department.
The case involved one child under the age of 13. Williamson has remained in custody at the Mercer County Jail on $250,000 bond since his August of 2019 arrest.
