ELIZABETHTOWN A former member of the AuSable Valley Central School Board of Education has admitted to having sex with an underage girl. Anthony Deyoe plead guilty in Essex County Court to criminal sexual act in the third degree, a class E felony. Deyoe waived his right to indictment by a grand jury, opting to be prosecuted by superior court information. Arrested on Oct. 13, 2007 for allegedly having oral sex with a then-14-year-old girl, Deyoe, now 28, resigned from his post on the school board shortly afterward; a post he had held since 2001. A resident of AuSable Forks, Deyoe is also a former teacher. According to Essex County District Attorney Julie Garcia, Deyoe could face up to three years in state prison for the crime. Deyoe has been released on bail until his Sept. 16 sentencing hearing.
