YOUNGSTOWN, Ohio - A lawsuit has been filed against the Trumbull County Children Services Board and a former employee that the suit alleges sexually abused three young girls under the agency's watch.

Attorney David Engler filed suit in Mahoning County on Tuesday morning, saying that's where some of the crimes occurred.

Engler is calling on Trumbull County CSB to submit to an independent investigation, preferably by the Ohio Attorney General's Office and it's Bureau of Criminal Investigation.

The three alleged victims were teenagers at the time, but are now adults. Attorney Engler says they just want to make sure no other child has to go through what they did.

"The one was sexually assaulted for almost a year. The other two girls were brought from Trumbull County to Boardman Township to come shopping and then she took them right across from the mall to her own apartment and had them perform simulated sex acts," Attorney Engler said.

Tim Schaffner, the current director of Trumbull County Children Services says, "I am deeply troubled by comments made by Attorney David Engler at a recent news conference."

Schaffner says Engler's comments are inaccurate and patently false.

According to Schaffner, the alleged misconduct of that staff member was investigated by Warren police, the Child Assault Prosecution Team and Job and Family Services after a police report was filed in 2007 against the CSB employee. He claims the women who are part of today's civil lawsuit were interviewed at that time and there was no finding of misconduct against the employee.
