Joshua Young is charged with "complicity to murder" and "complicity to tampering with physical evidence" in the 2011 brutal beating death of his 14-year-old stepbrother, Trey Zwicker. Josh Gouker, Young's father and Zwicker's stepfather, initially blamed the murder on his son, but later pleaded guilty and has since said Young had no involvement. Gouker was already sentenced to life in prison with the possibility of parole after 20 years for the death of his stepson.
According to the medical examiner, Zwicker was brutally beaten with a cylindrical object, such as a metal pipe, but the use of a bat wasn't ruled out. Gouker admitted to beating Zwicker to death with a pipe, but his cousin, Cassie, claims Young woke her up saying he killed Trey and needed her to help him get rid of the evidence, which included a bloody baseball bat. Zwicker had several injuries and the medical examiner said she thinks he was still alive, face down in the creek mud, when he ultimately died of asphyxiation. So what really happened that night and what led to Trey's death remains unknown.
Joseph Scott Morgan, former senior death investigator for the Fulton County Medical Examiner's Office in Georgia, joins Vinnie Politan in our Evidence Room to analyze the autopsy and what it reveals about the night Trey Zwicker was killed. Morgan says the report suggests two different weapons could have been used.
