CANTON, Ga. — A 20-year-old maintenance man has pleaded guilty to beating, raping and killing a 7-year-old north Georgia girl, who disappeared from a playground at her apartment complex and was found in a trash bin.

Ryan Brunn was indicted last week in the Dec. 2 killing of Jorelys Rivera (JOR'-ih-lees ruh-VIR'-uh). He responded "Yes, sir," when a judge asked if he was pleading guilty to the charges. The judge accepted his plea and sentenced him to life in prison.

The charges include murder, aggravated assault, aggravated battery, aggravated child molestation, false imprisonment and several other counts.

Authorities found the child's body three days after her mother reported her missing. Police believe Brunn snatched Rivera as she walked from the playground to her apartment to get sodas for her friends and killed her in a vacant unit.
