A former teacher at Early High School is accused of having sexual contact with an 18-year-old male student when she worked at the school, police said.

Joy Blackstock, 23, is free on $15,000 bond after being arrested Thursday on a charge of improper relationship between an educator and a student, Brown County Jail records state.

Blackstock was named in a sealed indictment on May 1, and Early Police Chief David Mercer said she met him at the jail after making arrangements through her attorney.

The charge, a second degree felony, is punishable by two to 20 years in prison.

Blackstock resigned last month after school officials investigated rumors about the alleged sexual contact and confronted her, Mercer said.

Blackstock was a choral teacher at the school, according to information in a November 2007 Bulletin article.

Blackstock, reached at her home Monday afternoon, declined to comment. Her attorney, Dana Smith, could not be reached for comment.

The indictment alleges sexual contact occurred “on or about” Nov. 18, 2007.

Mercer said the allegation surfaced in the “rumor mill” and the school’s principal, Bobby Fryar, did an investigation. “When they found out, they confronted her and she confessed. She resigned immediately,” Mercer said.

He said the case was reported to Early police on April 7, shortly after Blackstock resigned.
