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.
Young's social worker said she has never seen such dysfunction in a family in her 13 years on the job. In order to fully understand the case and trial, you must first understand the family dynamics.
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 death of his stepson.

Zwicker was beaten to death on May 10, 2011, after Gouker claimed he "snapped" when he confronted the teen about stealing marijuana and a lighter from him. After initially blaming Zwicker's murder on a group of teens, Gouker tried to pin the crime on his son. He later admitted that he acted alone in killing Zwicker and tried to deflect any responsibility on his son's part.
Gouker also claims he was upset with his then-wife and Zwicker's biological mother, Amanda McFarland, for having an abortion, and he wanted revenge.
Gouker testified that he killed Trey that night because he was stealing from him, but that wasn't the real reason he wanted his stepson dead. "His mother killed a couple of mine," he said.

Gouker and Terry Zwicker, Trey’s biological father, knew each other growing up. Gouker said in court that he hated Terry Zwicker. And to add to the confusion, Terry Zwicker actually dated Joshua Young’s biological mother, Angelina Young, years ago.
Cassie Gouker, the cousin of Josh Gouker, is also involved in this case. Gouker and Young were living with Cassie at the time of Zwicker’s murder, and she claims Young woke her up at 2:30 a.m. the night of Zwicker’s death and admitted to killing his stepbrother. Cassie was also allegedly sexually involved with Josh Gouker.
Despite Gouker's changing stories of what happened the night of Zwicker's death and his subsequent guilty plea, prosecutors have revealed no plans to drop the charges against Young, who faces life in prison if convicted. The charge of "complicity to murder" means prosecutors believe Young had knowledge of Gouker's plan to kill Zwicker, but failed to do anything to stop it.
Prior to his stepbrother's death, Young had been living in foster care after his mother, Angelina Young, died of a drug overdose in June 2010. Young was returned to his father's care a few months after Gouker was released from prison in September 2010.
