The Georgia Bureau of Investigation released the body of admitted murderer Ryan Brunn to a North Georgia funeral home after a GBI autopsy Friday determined his cause of death. Brunn, 20, pleaded guilty last week to the Dec. 2 sexual molestation of 7-year-old Jorelys Rivera of Canton and was sentenced to life in prison. Two days later he committed suicide at the Georgia Diagnostic and Classification Prison in Jackson.  A spokesman for Banister Funeral Home in Dahlonega on Tuesday declined, at the family's request, to give details of any memorial service.
