LOUISVILLE, Ky. (WDRB) -- Day two of testimony continued Thursday in the murder trial of Joshua Young.

Young is charged with complicity to murder and tampering with physical evidence in the murder of his stepbrother, Trey Zwicker.

Zwicker's body was found behind Liberty High School by students and faculty members in May of 2011. He had been brutally beaten. He was 14 years old.

Joshua Gouker -- Young's father and Zwicker's stepfather ---admitted to the murder. Last week he was sentenced to life in prison without the possibility of parole for 20 years.

Prosecutors argue they believe Joshua Young helped his father kill Zwicker. 

The second day of testimony began with an LMPD evidence detective taking the stand. As part of her testimony, she showed jurors a crime scene video from the day Trey Zwicker's body was found.

Afterwards, she introduced multiple pieces of evidence found at the scene. Young's fingerprints were not found on those items.

Amanda McFarland, Zwicker's mother, also took the stand. She claims Gouker was abusive, and following her son's death she began questioning Gouker.

"He became extremely angry that I would doubt him," says Amanda McFarland.

She says when she tried to sleep with Zwicker's pillow, Gouker lashed out.

 "Josh Gouker told me not to bring my dead son to bed with me."

Amanda McFarland described his behavior as violent and controlling, even threatening to kill her.

The defense tried to paint a picture of two step-brothers who got along, showing pictures of them playing video games together.  But Zwicker's mother said it was untrue.

Zwicker's uncle testified that he was at the house not long before Zwicker was killed, and had just played basketball with the teen. He told jurors he has always believed Gouker was a violent man, and did not support his sister's relationship with him.

Trey Zwicker's father understands, there's a reason behind all the Gouker talk, since Gouker admitted to the murder.

He's simply hoping for more questions about Josh Young's alleged involvement, and his relationship with Trey Zwicker.

 "I really can't follow what they're doing at this point, what they're motives are, but I'm sure there's a reason why and towards the middle portion or the end we'll figure out where they're going with this," says Terry Zwicker.

More than 2 years after the crime, Terry Zwicker is patiently waiting for all the answers.

"I'm here for my son. I'm here for the justice of my son, but also in reality, I want to know what happened to my son. What led up to that," says Terry Zwicker, who spoke to WDRB on Thursday. He testified in court on Wednesday.

On Wednesday, defense attorney Pete Schuler told jurors that Young should not have to pay for the mistakes of his father.

"Joshua is not guilty of murder," Schuler said. "He's not guilty because he didn't do it. He wasn't there when it happened."

Young, now 17, has been held at a juvenile detention center since his arrest. Although he was 15 at the time of his arrest, he is being tried as an adult.
