Roach, 31, could face up to two years in prison if she is convicted on the indicted charge of violation of the sexual offender registry law. She could also owe the balance of her original six-year sentence for aggravated statutory rape if she is convicted and her probation violated.Mrs. Roach served 270 days of a six-year sentence last year while her husband, George C. Roach, 31, served 108 days for aggravated statutory rape.The married couple had sex with a 16-year-old on at least two different occasions, one in March and one in September 2007.
