WALTONVILLE — A 25-year-old Waltonville man was sentenced Tuesday in Jefferson County court to 15-years in the Illinois Department of Corrections after he pleaded guilty to sexually assaulting a child.

Billy Mayes was arrested in 2017 and charged with two counts Class X felony charges of predatory criminal sexual assault of a victim under the age of 13.

He has remained in the Jefferson County Jail since his November 2017 arrest with bail set at $250,000.

The case against Mayes was scheduled to go to jury trial in May. He instead entered into a plea agreement with the state Tuesday in which he pleaded guilty to one of the charges in exchange for the second charge being dismissed.

Mayes was given credit for 504 days served in the Jefferson County Jail.
