A Union County man has pleaded guilty to sexually assaulting a five-year-old child, admitting to conduct that is both deeply disturbing and beyond understanding.

Robin Scott Atkinson, 64, of Marysville, entered a plea of guilty today in the Union County Court of Common Pleas to Rape of a Child Under 10. The guilty plea ensures that the victim and the victim’s family will not have to endure the trauma of testifying in court.

Sentencing is scheduled for December 19, 2025. Atkinson faces a potential prison sentence of life without parole or 15 years to life, and he will be required to register as a Tier III sex offender.

Atkinson, who had been free on a $250,000 appearance bond, requested that his bond be continued pending sentencing. The State moved to revoke his bond, and the Court agreed, ordering that Atkinson be remanded into custody. Deputies immediately took him from the courtroom to the Tri-County Regional Jail.
