COLUMBUS, Ohio – A former Columbus high school substitute teacher was sentenced to 90 days in jail and three years of probation after she was found guilty of knowingly showing students an inappropriate film in class.

Columbus City Schools fired substitute teacher Sheila Kearns, 58, after officials realized she played the “The ABCs of Death” to five Spanish classes she was covering in April 2013. The movie depicts 26 graphic deaths – one for each letter of the alphabet – in scenes that included full-frontal nudity and sex, The Columbus Dispatch reports.

Throughout her trail, Kearns’ attorney Geoffrey Oglesby insisted his client did not view the movie beforehand, and had her back to the screen during all five classes she showed the movie to students. Kearns was charged with five counts of disseminating matter harmful to juveniles, which requires advance knowledge of the content, according to the news site.

Kearns was convicted of four counts in January because the jury wasn’t convinced she reviewed the film before her first class, but should have had knowledge of the content in subsequent showings.

Franklin County Judge Charles A. Schneider told Kearns he didn’t buy her story – that she had her back to the screen for five classes – and called her claim to be unaware of the content “unconscionable” at her sentencing Wednesday.

“There’s no way you’ll persuade me that’s what happened,” he said, according to the Dispatch.

Two students testified in Kearns’ trial that the teacher did watch the “disturbing” movie with students, who went “crazy” during the graphic flick until an assistant principal eventually found out and confiscated the movie, the New York Post reports.

“Prosecutors said the movie’s title should have tipped off Kearns that she should check it out before showing it to her students, who ranged in age from 14 to 18,” according to the news site. “After the conviction, the jury foreman said it wasn’t proved at trial that Kearns was aware of the movie’s content the first time she showed it but she would have known by the second, third, fourth and fifth showings.”

Schneider also took the school district to task for assigning Kearns to a long-term substitute position teaching Spanish when she cannot speak the language, the Dispatch reports.

“This is what happens when you put a teacher in a class that she cannot teach,” Schneider said.

“They put a permanent substitute in a high school Spanish class who can’t speak Spanish at all. Here we are, with the Columbus public schools telling us what wonderful things (they) are doing.”

Kearns declined comment after her sentencing, and instead handed a prepared statement to a Dispatch reporter that quoted Galatians: “Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap.”

Kearns is scheduled to serve her 90-day jail sentence starting April 10, but Schneider said he’d delay her incarceration if she appeals her conviction. Oglesby said she plans to appeal, the Dispatch reports.

The Ohio Department of Education permanently revoked Kearns’ teaching license upon her conviction.
