GALLIPOLIS — Gallia County Common Pleas Court Judge D. Dean Evans sentenced Robert H. Erwin to serve 15 years in prison during a hearing Friday.

Erwin, 67, Gallipolis, pled guilty to three counts of unlawful sexual conduct with a minor in December 2009.

The former Little League coach was indicted in June after being accused of molesting at least a dozen boys dating back to the 1980s. The three counts he pled guilty to involved a 13-year-old male victim between April and May 2009.

The victim’s mother spoke in court Friday and asked Evans to impose a full 15-year sentence, which is the maximum allowable on all counts. Gallia County Assistant Prosecutor Pat Story also asked Evans to honor the plea agreement and sentence him to 15 years, “to punish Robert Erwin and protect the public.”

Evans complied, ordering Erwin to serve five years per count consecutively for a total of 15 years in prison.

Erwin declined to address the court Friday, as did Defense Attorney William Eachus on his behalf.

Pursuant to his guilty plea, Gallia County prosecutors agreed not to file any other charges of a similar nature against Erwin regarding any other alleged victims.

Upon Erwin’s release from prison, he will be classified as a Tier II sexual offender and be required to register in person with the sheriff’s office every 180 days for 25 years.

Evans further ordered him to have no contact with the victim and pay court costs. As of Dec. 9, Erwin had 26 days time served. During sentencing, Evans noted that he had no prior adult convictions.
