South Carolina news outlets are reporting a story about a Union County high school student who grabbed his teacher's phone, found nude pictures of her, and shared them with his friends. But it's the teacher—not the student—who's in hot water.

Union County High School teacher Leigh Anne Arthur says she left her phone on her desk for a few minutes while she went out on a routine patrol of the school's hallways. A 16-year-old student opened her phone, which wasn't protected with a password, and found pictures of Arthur that included shots of her partially undressed. The student used his own phone to take pictures of the partial nudes and send them around.

"He told the whole class that he would send them to whoever wanted them,” Arthur told TV station WSPA. The student who took the pictures "told me 'your day of reckoning is coming,'" she added.

Interim Superintendent David Eubanks held Arthur responsible because her phone was unlocked. Eubanks told WSPA that the teacher may have contributed to the delinquency of a minor. As for the student, Eubanks told The State newspaper that he is unsure if any discipline will be forthcoming.

Arthur was asked to either resign or face a disciplinary process that could lead to her being fired. Last week, she chose to resign.

Arthur said the pictures were Valentine's Day pictures taken for her husband, which she mistakenly left on her phone. In an interview with WYFF, Arthur questioned why the student wasn't being held responsible.

"He knows right from wrong," she said. "Where are you putting the moral of the student?"

Arthur taught mechatronics, a class that combines mechanical engineering, electrical engineering, and computer programming. Students at her school have created an online petition asking for her to be reinstated, but she's said she's not even sure she wants to go back at this point.

At the same time, she said she forgives the student who shared her photos. "He's 16. We all made stupid decisions at 16," she said.

Still, the Union County Sheriff's Office is investigating the matter following Arthur's complaint.
