Joshua Young is charged with complicity to murder for the 2011 beating death of his step-brother Trey Zwicker.
The 17 year old is being tried as an adult in the Jefferson County Circuit Court in Louisville, Kentucky. He is also charged with complicity to tampering with evidence.
Young's father and Zwicker's step-father Josh Gouker had pleaded guilty to the murder and was just sentenced to life in prison with the possibility of parole after 20 years. Gouker originally said his son was the killer, but later changed his story.
