A state police report investigating the death of a woman at a state run mental health facility is now in the hands of the prosecutor. Mary Knight, 67, was killed April 20th after she was run over by a driver at the Arkansas Health Center in Benton. Knight, who suffered from mental illness, was believed to have been inside the building, but she left and hid behind the vehicle, officials said. Police turned over their report to Saline County Prosecutor Robert Herzfeld. He could decide whether to file formal charges against the facility as early as Friday.
