A Georgia substitute teacher was arrested on Friday and charged with 19 counts of child molestation, the Carroll County Sheriff’s Office reports.

School officials notified investigators of “allegations of misconduct” by the teacher, and the subsequent investigation found that Amelia Ressler, 30, had “engaged in indecent and immoral acts while in the presence of school aged children,” the sheriff’s office said.

“It appears she was masturbating while the classroom was full of kids,” Ashley Hulsey, with the Carroll County Sheriff’s Office, told Fox5 Atlanta.

Ressler’s 19 counts represent one of each child in her second grade classroom at Mt Zion Elementary School.

Investigators found evidence of the indecent act when someone in the community saw a video and alerted the school, Hulsey said.

“We obtained video evidence because she videoed it herself and disseminated it and we were able to get a hold of that evidence,” she said.

Hulsey also said that investigators were talking with students and parents to determine what the kids saw.

“It’s one of these things the kids are going through that they shouldn’t,” she said. “The mental anguish that it’s causing these children and parents, that was our drive behind working this case, getting it down quickly, getting her put in jail as quickly as possible.”

Fox5 spoke with a parent of one of the second graders who said she knows Ressler.

“She graduated about the same time we did, so it just seems worse,” the parent said.

Fox5 said it wasn’t clear how long Ressler had been working with the Carroll County School District. She’s being held in the Carroll County jail without bond.
