INDIANAPOLIS -- A Former Mt. Vernon substitute teacher accused of having sex with students is set to plead guilty to one count of child seduction, according to prosecutors in Hancock County.

Kisha Nuckols was initially charged with four counts of child seduction and one count of dissemination of harmful material to minors.

Nuckols, previously a teachers aide/substitute teacher at Mt. Vernon Middle School, allegedly sent inappropriate photographs to a male student at the high school.

The student told investigators he and Nuckols had sex at least 10 times at her home, including when her children and husband were there.

In an interview with police, Nuckols reportedly admitted to having sex with the student and she "knew that the 'relationship' was wrong."

Nuckols also reportedly admitted to police that she had an inappropriate relationship with at least one other current Mt. Vernon Schools student and at least four other previous students.

A judge still has to sign off on the plea deal at a hearing on September 19.

Principal Scott Shipley is also facing a criminal charge for failing to report allegations surrounding Nuckols in a timely fashion.

Shipley said he didn't feel any students were in imminent danger due to school not being in session for spring break.
