New York- From www.newsday.com- Joan Tuckruskye, a Baldwin PTA mom who police said was found half-naked in a car with a 13-year-old boy was hit with additional criminal charges Wednesday after DNA tests showed she had sex with the boy, authorities said.

Joan Tuckruskye, 44, was charged with second-degree sexual abuse and second-degree criminal sexual act, police said.

Tuckruskye, a vice president of the Baldwin PTA, had been charged with endangering the welfare of a child on Dec. 12, 2008, after being caught with the boy in the parking lot of Meadow Elementary School in Baldwin.

Police determined Tuckruskye had sex with the boy by analyzing DNA taken from saliva on the boy’s clothes and body, authorities said.

Prosecutors have said in court documents that Tuckruskye admitted kissing the boy. The boy has denied having sex with her.

Tuckruskye is scheduled to be arraigned Wednesday on the new charges in First District Court in Hempstead.

If convicted on the felony charges, she faces a maximum of 2-1/3 to 7 years in prison.
