Joan Tuckruskye, 46, was sentenced Thursday to six months in jail and 10 years probation after pleading guilty to sexually abusing a 13-year-old boy.
She will also have to register as a sex offender for the next 20 years.
Police say Tuckruskye and the boy were found naked from the waist down in a car behind a Baldwin middle school in 2008. Prosecutors say the mother of three had sexual contact with the boy because her saliva was found on his body and clothes.
Tuckruskye pleaded guilty in April to charges of second-degree criminal sexual act, a felony.
