Mitchell Young, who is charged with murder in the baseball bat attacks on the Cipriano family, won't take the stand in his defense.
During a hearing Thursday, Young was asked under oath whether or not he wanted to testify.
"My decision is that I will exercise my right to remain silent," he said. "I believe that will be in my best interest."
Young is accused of helping Tucker Cipriano carry out brutal baseball attacks in April 2012 that killed Cipriano's father, Robert, and seriously injured his mother, Rose, and brother Sal.
Tucker Cipriano has already pleaded guilty to first-degree murder and attempted murder and faces an automatic penalty of life in prison without parole when he’s sentenced on July 9.
Defense attorneys contend that Mitchell Young was a victim of Tucker Cipriano.
Closing arguments began Thursday afternoon.
