She was found wearing her clothing and possibly burlap on her head. We've heard that an ear was cut off, numerous stab wounds, she did not die quickly, and when she did it was suffocation with a hand over her nose and mouth. Who knows what else she was subjected to. It sounds like the murderer covered her head after she was murdered, since he would need access to her nose and mouth to murder her. If she was abducted at 4:30 or 5:30PM, she was with the murderer for at least 3 hours if her body was dropped after dark (8:30PM+).
