Joshua Young, 17, has been charged with "complicity to murder" and "complicity to tampering with physical evidence" in the beating death of his 14-year-old stepbrother, Trey Zwicker.
Josh Gouker, Young's father and Zwicker's stepfather, was already sentenced to life in prison with possibility of parole after 20 years after he pleaded guilty in the murder of his stepson.

What exactly led to Zwicker's death remains unknown, but what we do know is that Young's social worker said, in court testimony, that she has never seen such dysfunction in a family in her 13 years on the job. A few months after Gouker was released from prison in September 2010, he got back together with his then-wife Amanda McFarland, Trey Zwicker's mother.
Gouker ultimately regained custody of his son, Joshua Young, in March 2011, and they moved in with Gouker's cousin just a few doors down from McFarland's home. Gouker's role in the lives of his biological son and his stepson has been under serious scrutiny.
Gouker has a violent criminal history, including charges of robbery, assault and now murder. Less than two months after Joshua went to live with his father, his stepbrother, Zwicker, was found dead. When Gouker was sentenced for Zwicker's murder, his sentence also included two counts of animal torture for allegedly beating a dog to death with a bat and throwing a cat out of a second-story window. Young allegedly filmed his father beating the dog to death.
After initially blaming Zwicker's murder on his own 15-year-old son, Gouker has since pleaded guilty and repeatedly denied Young's involvement. What attorneys hope to unveil in court is whether Young actually played a role in his stepbrother's murder and the details of what exactly happened that night.
