AUGUSTA — A Corinna man pleaded guilty Tuesday to sex offenses dating from more than a quarter-century ago.

Glenn A. Graves, 57, was scheduled to go on trial Tuesday in Kennebec County Superior Court on three charges of gross sexual misconduct that occurred between Oct. 9, 1985, and April 1, 1987.

The victims of those offenses, which occurred in Winthrop, were two girls under age 14. The case was investigated by Detective Peter Struck, of the Winthrop police, and came to light as he was investigating an unrelated case in 2012, according to District Attorney Maeghan Maloney. Graves was indicted on the charges last November.

On Tuesday, Graves was sentenced to eight years in prison with all but two years suspended, and four years of probation, a sentence recommendation supported by the prosecutor’s office.

Conditions of probation ban Graves from contact with girls under age 16 and from being within 100 yards of one of the girls.

He also was ordered to pay restitution of $787, which the district attorney said was for airfare so one of the victims could travel from her home in North Carolina for the trial. The other victim lives in Maine.

On Tuesday, Maloney said the victims asked that Graves spend two years in jail.

“They wanted the certainty,” Maloney said. “They didn’t want to talk about what happened between 1985 and 1987. It’s not what I would like to see in a sentence, but I want to respect what the victims want. I want to give them some power back that they lost.”

Graves also must register as a lifetime registrant under the state’s Sex Offender Registry and Notification Act. Maloney said Graves is in poor health and does not present a threat to the community. He has no previous criminal record.

Graves’ attorney, Walter McKee, said on Tuesday that his client “decided it was time to end this case, albeit on the courthouse steps.”

In a document filed with the court earlier this month seeking to bar evidence from outside the time period in the indictment, McKee wrote, “This is not a case where there is a denial that sexual acts took place; rather, this case will center entirely around when the sex acts took place and whether the state can prove, beyond a reasonable doubt, that the sex acts took place during the time period alleged in the indictment.”

Graves is to report to jail on Friday to begin the jail portion of his sentence.
