A Tri-City teen already doing prison time for a sexual assault was back in court Thursday on new allegations he raped a boy five years ago.
Kristofer Alan Putnam, 17, pleaded innocent in Benton County Superior Court to first-degree child rape. His trial is set Dec. 27.
The victim recently told authorities that during the summer of 2005, he was playing with some boys near a Kennewick apartment complex when Putnam called him over behind some Dumpsters, according to court documents.
The boy was in elementary school at the time.

Putnam, who then was 12, forcibly grabbed the boy by the collar, pulled him back and covered him by the mouth so he couldn't speak, documents said.
Prosecutors allege Putnam sexually assaulted and raped the boy, who was reportedly able to describe it in detail for investigators.
Court records show Putnam pleaded guilty to an unrelated charge of first-degree child rape in May and was sentenced three months later to prison.
Putnam was ordered held on $300,000 bail in the county jail while this new case is pending.
