"The investigation did not substantiate any negligence on their part, and we believe the children are still safe there," Deputy Commissioner Rob Rosenbloom said.
No sanctions were imposed and no employees were disciplined, The Augusta Chronicle reported Sunday.
The newspaper used an open records request to obtain the investigation report of what happened on the night of Jan. 2. As a result of the case, four teenagers who were at the privately run drug and alcohol recovery program were indicted on charges of aggravated sexual battery.
The report, based on statements by the victim and two of the accused, describes how four large teens moved on the victim while the lights were out during a shift change. When he tried to yell for help, one grabbed him in a choke hold and pulled him to the floor. He was fondled and attacked with the handle of a toilet plunger, according to the report.
The file says that corrective actions taken by the company include adopting a zero-tolerance policy for "horse play" and assigning extra keys so counselors overseeing dormitories can keep watch over residents during shift changes.
An attorney for the family of the victim, David Groover, of Calhoun, Ga., said there is no evidence that steps have been taken to ensure that an assault doesn't happen again.
