But that explanation is not going over very well with anti-crime advocates.
"Failure to hold perpetrators accountable, regardless of their disabilities, sends the wrong message to victims of crime," Candida Manion, the executive director of the nonprofit Oklahoma Coalition Against Domestic Violence, told The Associated Press.
District Judge Wallace Coppedge gave Petty a suspended sentence after his negotiated guilty plea on three felonies, including rape.
“There is a lack of knowledge about sexual assault within the criminal justice system, and what we know about violent offenders is that they will reoffend,” Manion said.
Officials with the district attorney’s office are reviewing the case.
The camp where the attack happened, and where Petty worked as a cook, is run by the Baptist Convention of Oklahoma and is the largest youth camp in the nation, according to the AP.
