Autopsy: Ga Child Killer Hanged Self in Prison A 20-year-old maintenance man who had just begun a life sentence for molesting and killing a 7-year-old Georgia girl used his sweat shirt to hang himself in his prison cell, according to autopsy results released Friday. There's no indication of anything other than suicide in the Thursday death of Ryan Brunn, and a medical examiner found no other significant trauma on his body, the Georgia Bureau of Investigation said. Brunn on Tuesday pleaded guilty to the Dec. 2 killing of Jorelys Rivera, whose body was found in the trash compactor of the Canton apartment complex where she lived and where he had worked for about a month. Brunn was found unresponsive in his cell at 4:15 p.m. and was declared dead at a hospital at 5:37 p.m. After his guilty plea, a judge immediately sentenced Brunn to life in prison without parole. Brunn also apologized to the girl's family members, who sobbed in the front row of the courtroom when he graphically described how he killed her. The news of Brunn's death came the same day that Canton officials announced that the city's police Chief Jeff Lance had resigned after a scathing report found he took a "laid back" approach to the search for Rivera.
