LOUISVILLE (WHAS11) – The father of 14-year-old Trey Zwicker, who was found murdered back in 2011, is reacting to a four-page confession letter written by Josh Young.

In that letter, Young admits that he acted alone in the brutal killing of his step-brother.

Zwicker's body was found behind Liberty High School, in Louisville.

After Young's father Josh Gouker took the fall for the murder, Young was found not guilty and walked free.

Gouker is now serving a life sentence.

Zwicker's dad, Terry Zwicker, was shocked to hear about Young's confession letter but said he always had doubts.

"The truth is there but the words are lies so the only way you're going to follow this story is you're not listening to the words coming out of the mouth, you're watching the actions, and the actions speak clearly of what's going on,” Terry Zwicker said.

Young is in a federal prison on a weapon's charge.

The Jefferson County Commonwealth Attorney's Office said they believe Young and Gouker killed Trey Zwicker together and will address any legal issues if and when any pleading is filed in court.

In the letter, Young, who is serving a sentence in federal prison for illegally owning a gun, admitted to the murder. He wrote in part that he did it alone and that it was not planned out. He also admitted that his father lied to keep him out of jail.

But Terry Zwicker said he is not convinced.

"Until they say what they actually did and their plan, we all know, then I guess really I'm just never going to be satisfied," Terry Zwicker said.

In his letter, Young said he is also interested in selling the rights to his story or working on a biography, but writes he wants to "clear up any and all misunderstandings and claim full responsibility for my actions."

"Young and Gouker, they did what they did," Terry Zwicker said. "Sure, they're notorious, they're famous. but everybody's not thinking about their names. They're thinking about Trey."
